	Modern Diesel \| Banks Power: Understanding Today’s Diesel by C.J. Baker
		The most significant differences from spark ignition engines are that diesels have no air throttle, fuel is injected directly into the combustion chamber, diesel fuel is used instead of gasoline, and the heat generated by the compression of the air in the cylinders ignites the fuel when it is injected.
		Diesels do have high pumping losses on the compression stroke due to high compression ratios, but that is offset by nearly equal rebound on the power stroke, as explained earlier.
		Until recently, diesel fuel injection was a purely mechanical function that varied the amount of fuel injected into the combustion chamber based on injection pressure that was controlled by fuel pump speed and the fuel throttle position that varied the fuel volume.

	The Diesel Engine
		The diesel internal combustion engine differs from the gasoline powered Otto cycle by using a higher compression of the fuel to ignite the fuel rather than using a spark plug ("compression ignition" rather than "spark ignition").
		In the diesel engine, air is compressed adiabatically with a compression ratio typically between 15 and 20.
		The ideal air-standard cycle is modeled as a reversible adiabatic compression followed by a constant pressure combustion process, then an adiabatic expansion as a power stroke and an isovolumetric exhaust.

	Design of a Diesel Cycle
		The Diesel cycle a closed cycle (where the system is a control mass), commonly used to model the cylinders of spark-ignition, internal combustion, automobile engines, i.e.
		The Diesel cycle is very similar to the Otto cycle in that both are closed cycles commonly used to model internal combustion engines.
		In the Diesel cycle, however, we are not adding all our heat to the cycle while the piston is stuck at the position providing the smallest volume, so the extremely high pressures we saw in the Otto cycle do not develop as quickly.

		Any diesel emission control system that replaces a muffler must continue to provide at a minimum the same level of exhaust noise attenuation as the muffler with which the vehicle was originally equipped by the applicantvehicle or engine manufacturer.
		Diesel emission control strategies are categorized by their PM reductions as follows: (1) Level one: the system has been demonstrated under these procedures to reduce PM emissions by at least 25 percent but less than 50 percent from the baseline emission level.
		For alternative diesel fuels that contain diesel as a base fuel such as emulsified diesel fuel and 80:20 biodiesel fuel (80 percent diesel/20 percent biodiesel), the base diesel fuel used to make the alternative diesel fuel can be used in place of the 10 percent aromatic California diesel reference fuel.

	Diesel cycle - Wikipedia, the free encyclopedia
		Diesel engines (Heat engines utilizing the Diesel cycle) are used in automobiles, power generation, diesel-electric locomotives, and submarines.
		Diesel cycle engines are nevertheless more efficient than Otto cycle engines overall, but only when power needs to be scaled.
		In North America, diesel engines are primarily used in large trucks, where the low-stress, high-efficiency cycle leads to much longer engine life and lower operational costs.

		Third, the study generally assumes that the comparative lifecycle benefits or costs of biodiesel and diesel fuel are proportional when biodiesel and diesel fuel are blended into one fuel, as in the popular 20% biodiesel/80% diesel blend known as B20.
		Soot is the heavy fl smoke portion of the exhaust that is essentially 100% carbon that forms as a result of pyrolysis reactions during fuel combustion.
		The study notes, 'In understanding the implications of higher lifecycle emissions, it is important to remember that emissions of hydrocarbons, as with all of the air pollutants discussed, have localized effects.

	Emission Standards: USA: Heavy Duty Truck and Bus Engines
		The current federal definition of a compression-ignition (diesel) engine is based on the engine cycle, rather than the ignition mechanism, with the presence of a throttle as an indicator to distinguish between diesel-cycle and otto-cycle operation.
		Therefore, the same diesel engine model used for the 8,500 - 10,000 lbs vehicle category may be classified as either light- or heavy-duty and certified to different standards, depending on the application.
		The diesel fuel regulation limits the sulfur content in on-highway diesel fuel to 15 ppm (wt.), down from the previous 500 ppm.

		However, fuel efficiency and fuel economy of biodiesel tend to be only 2%-3% less than #2 diesel." The overall lifecycle emissions of carbon dioxide (a major greenhouse gas) from biodiesel are 78% lower than the overall carbon dioxide emissions from petroleum diesel.
		Use of biodiesel in urban buses is potentially a viable option for controlling both life cycle emissions of total particulate matter and tailpipe emission of PM1 O." The study also finds that biodiesel reduces the total amount of particulate matter soot in bus tailpipe exhaust by 83.6%.
		The study notes, 'Petroleum diesel generates roughly five times as much wastewater flow as biodiesel.' The overall lifecycle production of hazardous solid wastes from biodiesel is 96% lower than overall production of hazardous solid wastes from diesel.

	Talk:Diesel cycle - Wikipedia, the free encyclopedia
		The details of the real-world application of these cycles in internal combustion piston engines are discussed, but the theoretical ideal processes - particularly with regard to the heat release profile, the main trait that differentiates the otto and diesel cycles - are not described.
		It is misleading to differentiate the diesel and gasoline engines on this basis, and is probably not appropriate to include this information on a page that is supposed to be primarily describing the idealized thermodynamic cycle.
		Diesel engines are inherently more efficient as they extract more heat from the combusted fuel due to a higher compression ratio - a diesel cycle will therefore require less fuel than a petrol engine for a given amount of work delivered.

		The Air Standard Diesel cycle is the ideal cycle for Compression-Ignition (CI) reciprocating Engines, first proposed by Rudolph Diesel over 100 years ago.
		The actual CI cycle is extremely complex, thus in initial analysis we use an ideal "air-standard" assumption.
		Thus the working fluid is a fixed mass of air undergoing the complete cycle which is treated throughout as an ideal gas, all processes are ideal, combustion is replaced by heat addition to the air, and exhaust is replaced by a heat rejection process which restores the air to the initial state.

		Thanks to our diesel piston aircraft engines the Warrior is already able to fly using the single military fuel to be introduced in the future.
		For a diesel in that range of power I think 2-stroke is the solution, otherwise the weight penalty compared with a gasoline engine is too high.
		Our forecast was expecting only a dozen diesel planes flying in 2006, because we expected a very slow take off of the market due to length of certifications, need for customer service, need for training personnel, etc. The number of diesel airplanes on the US register today is at least 25 and more probably 30.
