	Diesel engine - Wikipedia, the free encyclopedia
		The higher compression ratio allows a diesel engine to be more efficient than a comparable spark ignition engine, although the calorific value of the fuel is slightly lower at 45.3 megajoules per kilogram to gasoline at 45.8 MJ/kg.
		On large engines, pre-lubrication and slow turning of an engine, as well as heating, are required to minimize the possibility of damaging the engine during initial start-up and running.
		A gasoline (spark ignition) engine can sometimes act as a compression ignition engine under abnormal circumstances, a phenomenon typically described as "pinging" or "pinking" (during normal running) or "dieseling" (when the engine continues to run after the electrical ignition system is shut off).

		The air-fuel mixture is then ignited, usually by a spark plug for a gasoline or Otto cycle engine, or by the heat and pressure of compression for a Diesel cycle of compression ignition engine, at approximately the top of the compression stroke.
		In older engine designs, the cam shaft was in the crankcase and its motion transmitted by a push rod and rocker, the entire chain of parts being known as the valve train).
		Assuming the engine is robust enough in design not to break, the speed and therefore power output of the engine is typically limited by the ability to maintain a large volume flow of each of air-fuel mixture and exhaust gas through the respective valve ports.

	History of Diesel Engine-Yokayo Biofuels
		He envisioned an engine in which air is compressed to such a degree that there is an extreme rise in temperature.
		The early diesel engines were not small enough or light enough for anything but stationary use due to the size of the fuel injection pump.
		Diesel engines were altered to utilize the lower viscosity of the fossil fuel residue rather than a biomass based fuel.

	CMS—Chemical Kinetics of Hydrocarbon Ignition (Site not responding. Last check: 2007-11-06)
		Our modeling studies have demonstrated that this single reaction is responsible for numerous combustion phenomena—including engine knock (Figure 1) and octane number in SI engines, ignition and cetane number in diesel engines, as well as ignition in many other combustion systems, such as the laboratory rapid compression machine and pulse combustors.
		In particular, the need to provide for the wide ranges of engine speeds and loads which are characteristic of transportation applications appears to be very difficult without a transition to conventional SI operation at the higher levels of load required for acceleration and climbing steep hills.
		An HCCI engine for this type of application could operate with natural gas, gasoline, diesel fuel, or other special use fuel, and Livermore’s kinetic models would be used to describe the ignition kinetics for any of the chosen fuels.

		Off-road diesel engines are a source of concern for public health, as their emissions contribute to atmospheric levels of PM and ground-level ozone, which are the main components of smog, a noxious mixture of air pollutants that can often be seen as a haze in the air, especially over urban centres.
		Engines that are sold only in Canada will be required to demonstrate compliance according to the procedures set out in the proposed Regulations, which are aligned with the U.S. EPA requirements.
		In the case of an engine other than one referred to in subsection 14(2), evidence of conformity required under paragraph 153(1)(b) of the Act shall be obtained and produced by a company in a form and manner that is satisfactory to the Minister instead of that specified in section 16.

		Stationary HCCI engines could replace the spark-ignited and diesel engines currently used for backup-power generation and in businesses such as hotels where recovered exhaust heat is used for swimming pools and other facilities.
		In the HCCI engine, fuel is homogeneously premixed with air, as in a spark-ignited engine, but with a high proportion of air to fuel.

		Central parts in the project were the progress of the HCCI combustion process, the influence of charge homogeneity on the combustion process and sources of UHC and CO emissions in HCCI combustion.
		Towards the end of combustion, the expanding areas of burned gas compress the areas of unburned gases, generating strong gradients between burned and unburned areas.
		Due to the cool gas along the combustion chamber walls and in the crevices, the combustion in these areas is delayed or not at all initiated.
