What are the four-stroke of a diesel engine?
A four-stroke diesel engine resembles a gasoline engine as it works on the four-stroke cycle, that is: admission, compression, power and exhaust.
What are the three main reasons for high fuel efficiency in diesel engines?
The diesel engine’s use of lean mixtures, higher compression ratios, and lack of need for throttling the intake charge are some of the factors that lead to the diesel’s thermodynamic cycle efficiency advantage over theSI gasoline engine.
What are the three main reasons for high fuel efficiency in diesel engines quizlet?
Diesel engines operate at higher compression ratios than gasoline engines. Higher ratio than gasoline engines. Results in greater thermal expansion. more fuel energy converted into useful power.
Why efficiency of diesel engine is high?
The diesel engine has the highest thermal efficiency (engine efficiency) of any practical internal or external combustion engine due to its very high expansion ratio and inherent lean burn which enables heat dissipation by the excess air.
