The Difference Between Diesel Engine And Gasoline Engine

What is the biggest difference between a diesel engine and a gasoline engine?

1. The pressure in the cylinder is different. The diesel engine compresses air in the compression stroke stage; the gasoline engine compresses the gasoline and air mixture in the compression stroke stage

2. Different ignition methods. Diesel engines rely on atomized diesel to spray high-pressure gas for spontaneous combustion; gasoline engines rely on spark plugs to ignite
