2. 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 ...

3. Cold start (automotive) - Wikipedia

   en.wikipedia.org/wiki/Cold_start_(automotive)

   Generally speaking, diesel engines have more difficulty starting at low outside temperatures than gasoline engines, and electric engines have the most problems. Diesel engines do not use spark plugs to ignite the air fuel mixture and rely only on the heat generated by compression alone to ignite the fuel.

4. Diesel engine - Wikipedia

   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).

6. Diesel engine runaway - Wikipedia

   en.wikipedia.org/wiki/Diesel_engine_runaway

   Diesel engine runaway is an occurrence in diesel engines, in which the engine draws extra fuel from an unintended source and overspeeds at higher and higher RPM, producing up to ten times the engine's rated output until destroyed by mechanical failure or bearing seizure due to a lack of lubrication. [1]

7. Engine knocking - Wikipedia

   en.wikipedia.org/wiki/Engine_knocking

   This sudden increase in pressure and temperature causes the distinctive diesel 'knock' or 'clatter', some of which must be allowed for in the engine design. [ citation needed ] Careful design of the injector pump, fuel injector, combustion chamber, piston crown and cylinder head can reduce knocking greatly, and modern engines using electronic ...
