New 40 hp. Another key difference to diesel . Physics of Nuclear Kinetics. One of the key parameters of such engines is the change in volumes between the top dead center (TDC) to bottom dead center (BDC). Plus, even a little gas can damage the fuel pump as well as the fuel injectors. In 1885 he and Maybach created an engine called the "Grandfather Clock" engine and built a two-wheeled frame around it. Expansion. The U.S. Department of Energy's Office of Scientific and Technical Information The Diesel engines have the compression ratio that normally exceed 14:1 and ratios over 22:1 are also common. In a few years after the Otto engine was developed engine power rose until it reached 1000 hp. A typical value for an air/fuel mixture is k = 1.35. In 1876 Otto built an internal-combustion engine utilizing the four-stroke cycle (four strokes of the piston for each ignition). Marine diesel engines are very similar to the self-ignition engines in heavy-duty vehicles, but they are generally larger, more complex, and operate with higher efficiency. This ratio is usually 8 to 1 to 10 to 1 in most modern Otto engines. [4], Gottlieb Daimler was technical director and Wilhelm Maybach was the head of engine design. One of key parameters of such engines is the change in volumes between top dead center (TDC) to bottom dead center (BDC). The network for one cycle can be calculated using the heat added and the thermal efficiency: Wnet = Qadd . How do you tell if an engine is 2 or 4-stroke? Otto fuel II was invented by Otto Reitlinger in 1963 (although tests with the substance had taken place before, for example in 1960[1]); it is named after Reitlinger and for being the second iteration of the fuel (sometimes it is known simply as Otto fuel). It is based on constant volume heat addition (combustion) and heat rejection processes, and isentropic compression and expansion. 2) You may not distribute or commercially exploit the content, especially on another website. In Scotland and France, shale oil was used as fuel for the first 1898 production Diesel engines because other fuels were too expensive. The air standard assumption allow us to treat air as working fluid, and the combustion of fuel is replaced by constant volume heat addition process, exhaust is replaced by constant volume heat rejection. The Smethwick Engine is a Watt steam engine made by Boulton and Watt, which was installed near Birmingham, England, and was brought into service in May 1779. Petrol engines can often be adapted to also run on fuels such as liquefied petroleum gas and ethanol blends (such as E10 and E85).. Other consequences are the increase of the fuel consumption and the pollutant emission. What is claimed is: 1. This engine that uses four cycles in its creation of power. Hydrogen containing gases can be found as by-product from steel ( furnace gas) or chemical process, or . The Otto cycle consists of four reversible processes, two being adiabatic processes and two being isovolumetric processes. MEP of an atmospheric gasoline engine can range from 8 to 11 bar in the region of maximum torque. The engines were initially used for stationary installations, as Otto had no interest in transportation. This centralized distant heat dissipation system also helps to keep the engine building cool. Nikolaus Otto is generally credited with building the first-four-stroke internal combustion engine in 1876. In Otto cycle at the time of heat addition, the piston is at TDC where as in diesel cycle when the piston is in backward stroke, the heat addition begins and last at a portion of piston stroke. The temperature at the end of adiabatic expansion is T4 = 800 K. At the beginning of calculations we have to determine the amount of gas in the cylinder before the compression stroke. Specific heat capacity at constant air pressure and room temperature at atmospheric pressure: Specific heat capacity at constant air volume at atmospheric pressure and room temperature: J. R. Lamarsh, Introduction to Nuclear Reactor Theory, 2nd ed., Addison-Wesley, Reading,MA (1983). The function of this part is to completely shut off the air intake at the carb when you turn off the ignition. Before diesel fuel had been standardised, the majority of diesel engines typically ran on cheap fuel oils. 1) You may use almost everything for non-commercial and educational use. 3. U.S. Department of Energy, Nuclear Physics and Reactor Theory. Sadly, even with regular car maintenance such as a tune-up or an oil change, todays gasoline engines are only around 30 to 35 percent efficient, which means roughly 65 cents out of every dollar you spend on gas goes to waste. It's not perfect, though, as it has been observed that running an engine on hydrogen can cause premature ignition - this can cause backfiring. Save my name, email, and website in this browser for the next time I comment. Typically, the drop-off is in the same range as the reduction in peak engine power (3-5 percent). The expansion ratio of this engine was much more effective than that of the 1860 Lenoir engine and gave the engine its superior efficiency. 20. Expansion. Wise, David Burgess. It is known now as the Otto Cycle engine. The main difference between Otto cycle and Diesel cycle is that in Otto cycle heat addition takes place at constant volume and in diesel cycle heat addition takes places at constant pressure. The first version used a frame to stabilize the rack. Daimler always referred to his design as an explosion engine, to contrast it against Otto's engine and was able to evade paying royalties to Otto. Therefore, the vast majority of Otto engines operate according to the 4-stroke operating cycle. The primary difference (as most of you already know), is that petrol engines use spark plugs to ignite the air-fuel mixture, while diesel engines rely on heavily compressed air without any spark plugs. Did Matthew Lewis Wear Prosthetic Teeth In Harry Potter? 4. This design has the advantage of requiring no external battery, and is how modern portable gas engines operate, incorporating the magnet portion of the magneto into the flywheel. Combustion chamberOtto cilco thermal engine. The ideal Otto cycle consists of the following operations 1-2 Adiabatic compression. In real engines, there are always some inefficiencies that reduce the thermal efficiency. The mention of names of specific companies or products does not imply any intention to infringe their proprietary rights. In compression ignition, air is first compressed and heated; fuel is then injected into the cylinder, causing it to self-ignite. During WWII Otto engines were run on more than 62 different fuels, such as wood gas, coal gas, propane, hydrogen, benzene, and many more. The Otto Cycle engine was eventually adopted to run on Ligroin and eventually gasoline, and many gases. However, the 2-stroke Otto cycle is little used because of the loss of mixture that occurs through the exhaust and the consequent high fuel consumption. It is an alternative engine capable of converting the chemical energy of the fuel into mechanical energy by means of a thermodynamic reaction. The engine is limited to light fuels. Nitrates of polyhydric alcohols such as this have been used in medicine for the treatment of angina pectoris, and as explosives since the mid-nineteenth century. K. O. Ott, W. A. Bezella, Introductory Nuclear Reactor Statics, American Nuclear Society, Revised edition (1989), 1989, ISBN: 0-894-48033-2. The L-head had an alloy crankcase, a single iron casting for each cylinder block and head, side valves, a flat-plane crankshaft and a displacement of 5.1 L (314 cu in). As can be seen, the MEP is useful characteristics of an engine. The Cookies Statement is part of our Privacy Policy. Nikolaus Otto is generally credited with building the first-four-stroke internal combustion engine in 1876. Let's look at the internal combustion process in more detail in the next section. It operates on either a two-stroke or four-stroke cycle (see figure); however, unlike the spark-ignition gasoline engine, the diesel engine induces only air into the combustion chamber on its intake stroke. We hope, this article, Otto Cycle Otto Engine, helps you. January1993. As for 4-stroke engines, they run on gasoline without any oil mixed in and the piston goes up and down two times for every combustion cycle, hence its called a 4-stroke. However, 4-stroke engines require valves for both the intake and exhaust that must operate with high precision, making this engine format more . Visit our Privacy Policy page. Maximum displacement was 1,062 cu in (17.4 L). The Otto Cycle, describes how heat engines turn gasoline into motion. Required fields are marked *. or gas can and oil can symbols on it. It is the one of most common thermodynamic cycles that can be found in automobile engines. After 14 years of research and development Otto succeeded in creating the compressed charge internal combustion engine May 9, 1876. The Otto engine operates with a mixture compressed in a cylinder by a piston. The compression ratio in a gasoline-powered engine will usually not be much higher than 10:1 due to potential engine knocking (autoignition) and not lower than 6:1. Since neither of them knew of the other's patent until engines were made in both countries, there was a lawsuit. sweet, fruity and minty),[citation needed] reddish-orange, oily liquid that is a mixture of three synthetic substances: propylene glycol dinitrate (the major component), 2-nitrodiphenylamine, and dibutyl sebacate. By 1889 more than 50 companies were manufacturing Otto design engines.[8]. MEP of an atmospheric gasoline engine can range from 8 to 11 bar in the region of maximum torque. The cylinder arrangement of the compression engine was horizontal. It featured a slider valve control with gas flame ignition, which overcame the problems that Lenoir could not overcome with electric ignition which was unreliable at that time. The engine is limited to light fuels. Gasoline is made up of light hydrocarbons with a high calorific value, which evaporate easily. J. R. Lamarsh, A. J. Baratta, Introduction to Nuclear Engineering, 3d ed., Prentice-Hall, 2001, ISBN: 0-201-82498-1. A stroke refers to the full travel of the piston along the cylinder, in either direction. In the middle of the twentieth century, a typical, In 2014, new regulations were introduced for. "Daimler: Founder of the Four-Wheeler", in Northey, Tom, ed. diesel engine, any internal-combustion engine in which air is compressed to a sufficiently high temperature to ignite diesel fuel injected into the cylinder, where combustion and expansion actuate a piston. Other makers such as Daimler perfected the Otto engine for transportation use. The fuel was still Illuminating Gas just as Lenoir's and his own atmospheric engines had used. After Mr. Diesel introduced his engine, the petroleum industry cashed in by using a byproduct of petroleum distillation to power the engine. Nicolaus August Otto as a young man was a traveling salesman for a grocery concern. A low compression ratio does not require a high octane fuel to avoid this phenomenon, in the same way, a high compression requires a high octane fuel, to avoid the effects of detonation, that is, auto-ignition occurs. The engine was 8.8 ft (2.65 m) tall and weighed 1,600 lb (725 kg). In real engines, there are always some inefficiencies that reduce the thermal efficiency. Visit our Editorial note. It is used gaseous fuels which are free from pollution. Although for a given compression ratio the Otto cycle has higher efficiency, because the Diesel engine can be operated to higher compression ratio, the engine can actually have higher efficiency than an Otto cycle when both are operated at compression ratios that might be achieved in practice. The new ME-GA engine may be an LNG dual-fuel engine, but it has some pointers about the future as the engine maker focuses on its ammonia-fuelled engine for 2024. 1876: Nikolaus August Otto patented the first four-stroke engine in Germany. Co; 1st edition, 1965. Engine Definition. It can also refer to a device that converts one form of energy into another. Deutz is the world's oldest engine producer. The 18 liter Lenoir engine was able to produce only 2 horsepower. To prevent knock in SI engine the end gas should have low temperature, pressure and density, a long ignition delay and a non-reactive composition. Since the process is adiabatic, we can use the following p, V, T relation for adiabatic processes: Again, we can use the ideal gas law to find the pressure at the beginning of the power stroke as: p3 = mRspecificT3 / V3 = 5.9510-4 x 287.1 x 1926 / 55.56 10-6 = 5920000 Pa = 59.2 bar. The compression ratio in a gasoline-powered engine will usually not be much higher than, A turbocharged Subaru Impreza WRX has a compression ratio of, A stock Honda S2000 engine (F22C1) has a compression ratio of, Some atmospheric sportscar engines can have a ratio of, In 2012, Mazda released new petrol engines under the brand name. The atmospheric engine used a gas flame ignition system and was made in output sizes from 0.25 to 3hp (0.19 to 2.24kW; 0.25 to 3.04PS). Introductory Nuclear Physics, 3rd Edition, Wiley, 1987,ISBN:978-0471805533, G.R.Keepin. J. R. Lamarsh, A. J. Baratta, Introduction to Nuclear Engineering, 3d ed., Prentice-Hall, 2001, ISBN: 0-201-82498-1. Addison-Wesley Pub. It is not related to the Otto cycle.Otto fuel II was developed by US Navy in the 1960s for use as fuel in torpedoes. It is also used as a lubricating ingredient in shaving lotions, and a flavoring additive in non-alcoholic beverages, ice cream, ices, candy, and baked goods. Rudolf Diesel was granted a patent for his "Method of and Apparatus for Converting . Main purpose of this project is to help the public learn some interesting and important information about engineering and thermal engineering. MEP of a turbocharged gasoline engine can range from 12 to 17 bar. The oil to fuel mix ratio should be specified in your engines instruction manual. For instance, an electric generator converts mechanical energy into electrical energy, and an optical fibre transforms light into an electric currentsee the photoelectric effect. For example, some sportscar engines can have compression ratio up to 12.5 : 1 (e.g. The fuel was still illuminating gas just as Lenoir's and his own atmospheric engines had used. Wilhelm Maybach (1846-1929), one of the most important German engineers, perfected the construction, which was produced in large quantities already at the end of the year 1876. Which engine is more powerful petrol or diesel? In 1862 Otto attempted to produce an engine to improve on the poor efficiency and reliability of the Lenoir engine. This is the same engine that was first attempted in 1862. . The engines were initially used for stationary installations, as Otto had no interest in transportation. It can be used for plastics in use in the food packaging industry. In 1876, a German engineer, Nikolaus August Otto, advanced the study of heat engines by building the first working four-stroke engine. Which fuels can an Otto engine run on? The efficiency of Otto cycle is less as compared with the Diesel cycle. LiquidPiston has rethought the engine starting with first principles - revisiting the thermodynamic cycle - and innovating in a space that hasn't changed in over 100 years! Biofuels are still used in these engines. On a carbureted engine you may otherwise find a run-on solenoid. Amazingly, the KLR starts and runs . The Otto/Langen atmospheric engine ran at 12% efficiency and produced .5hp (0.37kW; 0.51PS) at 80 RPM. Using the ideal gas law, we can find the mass: m = p1V1/RspecificT1 = (100000 50010-6 )/(287.1 293) = 5.9510-4 kg. Petrol engine: Petrol engine works on the Otto cycle. There are no engines currently that can run on ammonia, or ammonia as dual-fuel, at today's standards and with the same operating conditions. Many engineers were also trying to solve the problem with no success. IES IAS) Previous Years GATE Questions Diesel fuels Q1. Tesla will reveal its semi-truck design tonight in a highly anticipated event in Hawthorne, California, reaching another goal in founder Elon Musk's "Master Plan" for the company. The principal current use of propylene glycol dinitrate is as a propellant in Otto fuel II. This is in contrast to igniting the fuel-air mixture with a spark plug as in the Otto cycle (four-stroke/petrol) engine. The intake air is at 100 kPa = 1 bar, 20 C, and the volume of the chamber is 500 cm prior to the compression stroke. This work was conducted in parallel to the work of Gottlieb Daimler and Wilhelm Maybach who also developed a carburetor which replaced the original hot tube ignition on the Daimler Reitwagen, and a magneto ignition system which formed the basis of the magneto of the Robert Bosch Corporation. [7], The cylinder arrangement of the compression engine was horizontal. This is in contrast to igniting the fuel-air mixture with a spark plug as in the Otto cycle (four-stroke/petrol) engine. The ECU is new and perfect! In petrol engines, the power developed is low due to the compression ratio, whereas in diesel engines, the power is more. Your email address will not be published. It is this engine (the Otto Silent Engine), and not the Otto & Langen engine, to which the Otto cycle refers. Daimler's fourteen-year-old son Adolf was the first person to ride on this motorized bicycle which is the first internal combustion engined motor vehicle. This allowed the use of liquid petroleum fuel for the first time and made the use of the engine in transportation feasible. [7] It is this engine (the Otto Silent Engine), and not the Otto & Langen engine, to which the Otto cycle refers. For a discussion of related thermodynamic principles, see. The Otto is one of the first engines to use a spark plug, which is a device that produces a small electric spark to ignite the fuel charge. Spark ignition engine. The injection feed of the Otto engine, in the case of multi-cylinder engines, has the following advantages:if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[320,50],'demotor_net-large-leaderboard-2','ezslot_3',141,'0','0'])};__ez_fad_position('div-gpt-ad-demotor_net-large-leaderboard-2-0'); On the contrary, this type of fuel supply of the gasoline engine has the following disadvantages that it is more complicated and expensive, especially with regard to regulation. In 1876, a German engineer, Nikolaus August Otto, advanced the study of heat engines by . Whereas,a diesel engine also known as Compression Ignition (C.I) engine works on the basis of Diesel cycle or Constant pressure heat addition cycle. Due to the characteristics of this type of heat engine, it can receive various names. A series of specifications required for the engine to function well and others of an environmental nature must be met, both regulated by law in most countries. If you want to get in touch with us, please do not hesitate to contact us via e-mail: [emailprotected]. Like other thermodynamic cycles, this cycle turns chemical energy into thermal energy and then into motion. The engine is limited to light fuels. The temperature at the end of an adiabatic expansion is T4 = 800 K. At the beginning of calculations, we must determine the amount of gas in the cylinder before the compression stroke. The Otto cycle consists of four reversible processes, two being adiabatic processes and two being isovolumetric processes. They disconnect the stock fuel system, run the engine completely out of gas, then stab the syringe into the intake boot ahead of the carburetor and let her rip. Otto Cycle - Otto Engine. The Otto engine was a large stationary single-cylinder internal combustion four-stroke engine designed by the German Nicolaus Otto. Nuclear and Particle Physics. Virtually all of the world's makers of automobiles produce vehicles using Otto cycle engines which are so ubiquitous as to be referred to as internal-combustion engines, gasoline engines, and spark-ignition engines. A Carnot engine is, simply, a reversible engine acting between only two heat reservoirs. In 1883 Daimler and Maybach created a .5hp engine that was small and efficient. Biodiesel offers an alternative to fossil fuel for cars, trucks, buses, trains, and farm equipment that have been traditionally run on petroleum based diesel fuel. The steam Rankine cycle is one of the highest utilized types of thermodynamic cycles for electricity production in the world . The simple ideal Rankine cycle is in fact the most basic vapor power cycle. The Otto cycle describes how internal combustion engines (that use gasoline) work, like automobiles and lawn mowers. The first torpedo to use it was the Mark 48 torpedo in the 1960s.[2][3]. The Otto cycle is more complicated than a Carnot cycle, in a number of ways: The working gas is physically pumped in and out of the cylinder through valves, rather than being sealed and reused indefinitely as in the Carnot engine. Nuclear and Particle Physics. "The documentation suggests it was not a big operation," he says, "but some small factory that produced shoes." Probably tank-cooled originally, the engine is now run on a continuous water flow system with a hot tube igniter. Finally, the fuel's energy density far surpasses the capacity of the electric battery used in other torpedoes, maximizing range. Qadd = mcv (T3 T2) = 5.9510-4 x 718 x 1220 = 521.2 J. A 4-cycle engine has two fill ports with each cap separately identifying the fuel tank from the oil sump. Otto engines can be fueled by carburetion or injection. E. E. Lewis, W. F. Miller, Computational Methods of Neutron Transport, American Nuclear Society, 1993, ISBN: 0-894-48452-4. Needing no oxidants and being a stable substance makes Otto fuel II ideal for use in the constrained environment of a submarine. Save some $$$$ and buy this now before its gone. Robert Reed Burn, Introduction to Nuclear Reactor Operation, 1988. During WWII Otto engines were run on more than 62 different fuels, such as wood gas, coal gas, propane, hydrogen, benzene, and many more. Yes, it will. D. L. Hetrick, Dynamics of Nuclear Reactors, American Nuclear Society, 1993, ISBN: 0-894-48453-2. : 14247 Horsepower: 175 hp @ 180 rpm Bore & stroke: 21in x 30in Engine weight: 49,000lb Flywheel diameter: 17-3/4in x 1-3/4in Ignition: Magneto and igniter Governing: Throttle. MEP of a turbocharged gasoline engine can range from 12 to 17 bar. The cap will usually state the oil to fuel mix ratio. A limited number of . It is characterized by the fact that, in a first theoretical approximation, all the heat is supplied at a constant volume. Another downside has to do with its low density . Which has more electron affinity carbon or nitrogen? MEP of an atmospheric diesel engine can range from 7 to 9 bar. This website does not use any proprietary data. No pumping work. What type of cycle is used in steam engine? What is the difference between Diesel cycle and Otto cycle? The Otto engine can run in 4-stroke or 2-stroke cycles. K. O. Ott, R. J. Neuhold, Introductory Nuclear Reactor Dynamics, American Nuclear Society, 1985, ISBN: 0-894-48029-4. In real engines, there are always some inefficiencies that reduce the thermal efficiency. The working gas is not monoatomic. Compression - The gas (fuel-air mixture) is compressed adiabatically from state 1 to state 2. "The documentation suggests it was not a big operation," he says, "but some small factory that produced shoes." Likely tank-cooled originally, the engine is now run on a continuous water flow system with a hot tube igniter. This engine used four cycles in its creation of power. To keep the machine running, it needs the small engine flywheel. The Otto engine can also use gaseous fuels or liquefied gas as well, but its use is less practical and therefore much less widespread.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'demotor_net-box-4','ezslot_1',140,'0','0'])};__ez_fad_position('div-gpt-ad-demotor_net-box-4-0'); Gasoline is obtained from crude oil in a refinery. [1] Daimler, which became Daimler-Benz, is the world's oldest automobile manufacturer. As can be seen, the MEP is useful characteristics of an engine. Modern portable engines excite the magneto with every flywheel rotation, and so use a cam-operated electric switch to prevent plug firing except for the power stroke of the engine (see wasted spark). The perfected system, for supplying different fuels to Otto engines with electronic fuel-injection comprises a tank (20) containing liquid gas (40) under pressure, a pumping unit (30) that delivers the liquid gas (40) to an injection nozzle (11) thad is also used for the injection of petrol. Answer (1 of 2): Work machines with OTTO engines (or SI petrol in the classical sense) are not the boldest solution. The main. We assume no responsibility for consequences which may arise from the use of information from this website. The fuel for an Otto engine is gasoline. Petroleum products normally used as fuel for diesel engines are distillates composed of heavy hydrocarbons, with at least 12 to 16 carbon atoms per molecule. The information contained in this website is for general information purposes only. 5 The Internal combustion engine (Otto Cycle) [VW, S & B: 9.13] The Otto cycle is a set of processes used by spark ignition internal combustion engines (2-stroke or 4-stroke cycles). The gas (fuel-air mixture) expands adiabatically from state 3 to state 4. Gas engines are providing a wide range of fuel flexibility from burning natural gas and a variety of non- natural gaseous fuels from low British Thermal Unit (BTU) gases as well as gases containing a high hydrogen content. Otto found a way to layer the fuel mixture into the cylinder to cause the fuel to burn in a progressive, as opposed to explosive fashion. MEP of a turbocharged diesel engine can range from 14 to 18 bar. It also has civilian applications as a solvent dye. As was derived in the previous section, the thermal efficiency of an Otto cycle is a function of compression ratio and : It this equation the displacement volume is equal to Vmax Vmin. Daimler continued the development of Otto's engine for transportation while Deutz switched to Diesel engines. There are certainly a few reasons why acetylene is not a very practical fuel for an IC engine. During WWII Otto engines were run on more than 62 different fuels, such as wood gas, coal gas, propane, hydrogen, benzene, and many more. January1993. The company's first application of its model was using 100% fuel-grade ethanol, not a blend, in a modified engine of a Class 8 truck. Ingestion of contaminated food or direct exposure at worksites can cause headaches, poor eyehand coordination, eye irritation, congested noses, nausea, dizziness, and difficulty breathing. For two engines of equal displacement volume, the one with a higher MEP would produce the greater net work and, if the engines run at the same speed, greater power. Who Can Benefit From Diaphragmatic Breathing? Deutz also developed the carburetor and a reliable low voltage ignition system in 1884. Otto fuel II is a toxic substance found in EPA National Priorities List. Look for stickers labeling the equipment (e.g., Four Cycle or No Fuel Mixing). These engines run small electric generators called diesel generators, often in remote areas as well as the engines of cars and trucks (both large and small). Co; 1st edition, 1965. Efficiencies exceeding 47% have been routinely recorded. Qadd = mcv (T3 T2) = 5.9510-4 x 718 x 1220 = 521.2 J. Later Otto engines employed a small magneto directly on the engine. The fuel is injected into the cylinder in both engines, but it is ignited with a spark plug in gasoline engines. What is 4-stroke fuel? Which is more efficient Otto cycle or diesel cycle? 6 Diesel Cycle. As of 2016, almost all of the petroleum-based diesel fuel available in the United Kingdom, mainland Europe, and North America is of a ULSD type. The engines use chemical energy in the fuel to produce mechanical energy. What is the difference between Otto engine and diesel engine? The major component of biogas is methane (CH 4) at 87% per volume of mixture. Abstract: In the 1890s, Rudolf Diesel invented an efficient, compression ignition, internal combustion engine that bears his name. A petrol engine (gasoline engine in American English) is an internal combustion engine designed to run on petrol (gasoline). Internal combustion engines provide outstanding drivability and durability, with more than 250 million highway transportation vehicles in the United States relying on them. What is the difference between Otto cycle and diesel cycle? What fuels can a diesel engine run on? Fueltech FT550 ECU Open box special. Contents Those who were jealous of the Otto patents (there were 25 patents) had 1 patent overturned in Germany largely because the court failed to understand the significance of Otto's layered charge system which overcame the problems of explosive combustion which destroyed all engine designs previously.
