1. Diesel Engines are more Efficient

One of the most significant advantages of a diesel engine compared to gasoline powered engines is that diesels are significantly more efficient. The engines are capable of converting approximately 45-50 percent of the fuel energy to power. The majority of gasoline engines are only able to convert approximately 30 percent of the gasoline energy to power the automobile. Additionally, diesels have a higher compression ratio than gasoline models (between 12-16 to one compared to 8-12 to one). Modern variants of the engines also benefit from not requiring a throttle plate like gasoline engines do. The absence of these plates allows the engine to avoid pumping losses which are energy losses that occur on gasoline powered engines when they attempt to intake air past the partially closed plates.
