Abstract

To maintain a proper engine temperature and better combustion of internal combustion engine anexperimental study is conducted with mixing additional substance into the combustion chambermixed with petrol. The additional substance added are water, hydrogen and methanol. Out of thethree substances mixed with the fuel, the overall engine temperature and combustion is identified.The injection method is organized using a fuel injection system or by a carburettor. Three differentmethodswerestudied,includingmethanol,water,andhydrogen.Theenginewasnaturallyaspirated and operated at stoichiometric condition. In each test, the percentage of injection wasvaried from 0 to 100% and the full crank rotation is taken into consideration. The effects of thecombustion at normal method and different injection methods were investigated and the overallcombustionisvalidated.Allinjectionmethodsareapromisingapproachwithsignificantimprovementinengineperformanceandknocksuppression. Thehydrogeninjectionmethodexhibits better a high energy content and burns cleanly, which can improve combustion efficiencyand reduce emissions. Adding water to petrol can improve fuel economy and reduce emissions.Methanol has a high octane rating and can improve engine performance when added to petrol andit is also a renewable fuel source and produces lower emissions. Of all the three methods it hascome to an end that by using methanol as the additional substance with petrol it can produce morepower outputwithlessengine temperature
