2. Diesel engine - Wikipedia

   en.wikipedia.org/wiki/Diesel_engine

   1952 Shell Oil film showing the development of the diesel engine from 1877. The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine).

3. Dieseling - Wikipedia

   en.wikipedia.org/wiki/Dieseling

   The ignition source of a diesel engine is the heat generated by the compression of the air in the cylinder, rather than a spark as in gasoline engines. The dieseling phenomenon occurs not just because the compression ratio is sufficient to cause auto-ignition of the fuel, but also because a hot spot inside the cylinder (spark plug electrode ...

4. Stratified charge engine - Wikipedia

   en.wikipedia.org/wiki/Stratified_charge_engine

   The Vespa ET2 scooter had a 50 cc two-stroke engine in which air was admitted through the transfer port and a rich fuel mixture was injected into the cylinder near the spark plug just before ignition. The injection system was purely mechanical, using a timed pumping cylinder and a non-return valve.

5. Diesel cycle - Wikipedia

   en.wikipedia.org/wiki/Diesel_cycle

   Many model airplanes use very simple "glow" and "diesel" engines. Glow engines use glow plugs. "Diesel" model airplane engines have variable compression ratios. Both types depend on special fuels. Some 19th-century or earlier experimental engines used external flames, exposed by valves, for ignition, but this becomes less attractive with ...

6. Two-stroke diesel engine - Wikipedia

   en.wikipedia.org/wiki/Two-stroke_diesel_engine

   Hugo Güldner designed what is believed to be the first operational two-stroke diesel engine in 1899, and he convinced MAN, Krupp and Diesel to fund building this engine with ℳ 10,000 each. [2] Güldner's engine had a 175 mm work cylinder, and a 185 mm scavenging cylinder; both had a stroke of 210 mm.

7. Indirect injection - Wikipedia

   At best such types differed only in the cylinder head and the need to fit a distributor and spark plugs in the petrol version whilst fitting an injection pump and injectors to the diesel. Examples include the BMC A-Series and B-Series engines and the Land Rover 2.25/2.5- litre 4-cylinder types.
