2-takts dieselmotor vs 4-takts dieselmotor?
Two-stroke diesel engine
Totaktsforbrændingsmotorer er mekanisk enklere end firetaktsmotorer, men mere komplekse med hensyn til termodynamiske og aerodynamiske processer, ifølge SAE's definitioner. I en totaktsmotor foregår de fire "cyklusser" i teorien om forbrændingsmotorer (indsugning, kompression, tænding, udstødning) i én omdrejning, 360 mekaniske grader, mens de i en firetaktsmotor foregår i to komplette omdrejninger, 720 mekaniske grader. I en totaktsmotor forekommer mere end én funktion på et hvilket som helst tidspunkt under motorens 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.
