The purpose of the study was to analyze the combustion and thermal efficiency with and without hydrogen enrichment

A comprehensive study was performed for a detailed analysis of combustion efficiency, thermal efficiency, indicated power, fuel concentration and temperature plots. The criterion of this study was to ensure high combustion efficiency. This study provided detailed information on a premixed single-component fuel and on dual-fuel cases.

Addition of hydrogen in the premixed case showed a trend of increase in the combustion efficiency, thermal efficiency, indicated power and encouraged a complete burn of the fuel mixture in the engine. The temperature decrease at high concentrations of hydrogen implies low emissions.

It shows that if a small amount of hydrogen is premixed with gasoline, it will encourage a complete burn which will burn the entire fuel vapor, thereby making it a cost effective process, and will reduce the emissions.
