2-takts dieselmotor mot 4-takts dieselmotor?
Two-stroke diesel engine
Tvåtakts förbränningsmotorer är enklare mekaniskt än fyrtaktsmotorer, men mer komplexa i termodynamiska och aerodynamiska processer, enligt SAE:s definitioner. I en tvåtaktsmotor sker de fyra "cyklerna" i förbränningsmotorns teori (insugning, kompression, tändning, avgas) under ett varv, 360 mekaniska grader, medan de i en fyrtaktsmotor sker under två fullständiga varv, 720 mekaniska grader. I en tvåtaktsmotor sker mer än en funktion vid varje given tidpunkt under motorns drift.
Two-stroke diesel engine
Two-stroke internal combustion engines are simpler mechanically than four-stroke engines, but more complex in thermodynamic and aerodynamic processes, according to SAE definitions. In a two-stroke engine, the four "cycles" of internal combustion engine theory (intake, compression, ignition, exhaust) occur in one revolution, 360 mechanical degrees, whereas in a four-stroke engine these occur in two complete revolutions, 720 mechanical degrees. In a two-stroke engine, more than one function occurs at any given time during the engine's operation.
