Enhancing thermal efficiency of engines from fuels
Enhancing thermal efficiency of engines from fuels
A combustion method that has been attracting attention for enhancing thermal efficiency in gasoline engines and reducing CO2 is called “super lean burn”, that increases the volume of air introduced into the engine.
ENEOS has been conducting research on increasing efficiency by combining a super lean burn engine and optimized fuel composition.
A super lean burn can increase efficiency by introducing more air into the engine, but combustion can become unstable in such a lean fuel condition.
In research to date, we have discovered that optimizing the fuel composition can achieve stable combustion in an even leaner region and significantly enhance thermal efficiency.
This approach can reduce the amount of fuel being used thereby contributing to a reduction in CO2 emissions and the effective use of carbon-neutral fuels in the transition period to carbon neutrality.
