Diesel Engine vs Gasoline Engine Efficiency

Diesel Engine vs Gasoline Engine

Are Diesel Engines Efficient vs Gasoline Engines? The rivalry between the gasoline engines and diesel engines has been there since the birth of both the engines, and the trophy of this competition keeps on changing its winner. This cat and mouse race between both the major types of internal combustion engines does not seem to end, as both the engines have their pros and cons. It now depends upon the user to select the engine as per the use requirements. However, still the factor of efficiency can be termed as a gauge to appreciate one kind of engine over another. The modern times are witnessing now the enhanced efficiency of gasoline engines over the diesel engines.

Highway Usage Edge

When both the gasoline engines and diesel engines are compared with regards to the factor of efficiency at higher speeds, especially for long distance travelling, the efficiency of the diesel engines has always been appreciated over the gasoline engines because at higher speeds higher compression ratios coupled with lean fuel burning due to rich air in the mixture has always given the diesel engines an inherent edge over the gasoline engines.

Future of Gasoline Engine

This inherent edge in diesel engines could not be overcome except for revolutionary introduction of the hybrid fuel gasoline engines. However still as a whole diesel engines enjoy the efficiency edge over the gasoline engines. The modern times though are witnessing the minimization of this edge of diesel engines over gasoline engines and the future of gasoline engines is expected to be much brighter than the diesel engines. It is also due to the stricter emissions regulations which are making diesel engines proving to be less efficient due to the exhaust of diesel engines, and this gap of efficiency between the two engines is expected to close within the current decade.

Newer Technology in Gasoline and Diesel Engines

Newer technology being introduced in the gasoline engines is ever changing at a very fast pace amalgamated with lots of versatility such as variable valve lift timed ignition, gasoline direct injection, multi-port fuel injection systems and introduction of turbochargers have added a lot to the efficiency of gasoline engines. Also affiliated improvements in the electronics and metallurgy have further enhanced the efficiency of gasoline engines. Further research towards lean burn combustion and the innovation in the technology of homogeneous charge compression ignition further decreases the gap between the efficiency of the diesel engines and gasoline engines. Research on shifting of gasoline engines on more energy dense fuels is also underway which can further prove to be a milestone in taking an edge over the more
