Diesel engines differ from gasoline engines in several key ways regarding design and operation.  Diesel engines waste less energy than their gas counterparts because they combust air using compression and don’t require fuel to be ignited by a spark plug. A diesel engine produces more torque than gasoline engines, making them better for heavy-duty applications. Diesel engines are also built stronger than gas engines to handle the greater internal compression.  All engines lose some of the fuel’s potential energy in
