Engineers may create diesel engines with higher compression ratios than gasoline engines because diesel has a higher compression resistance and is denser than light distillate fuels.
The thermal efficiency of an engine increases with increasing compression ratio. Shaker, circulation, and spray jet systems are three ways that engine oil is utilized to assist in cooling pistons. the diesel engine. a fuel-burning engine that runs on diesel. Fuel oil is directly injected into the cylinders of a diesel engine. The air itself is hot enough to ignite the diesel fuel without a spark due to the extreme compression. Cycle with four strokes.
