Performance characteristics of diesel engines

High thermal efficiency: Diesel engines have a high compression ratio (usually between 15-22), resulting in high thermal efficiency and energy conversion rate, which can effectively save energy. The thermal efficiency of a typical diesel engine is 30% -40%, which is higher than the 20% -30% of a gasoline engine.
