Abstract

The use of biopetrol fuel as alternative fuels in gasoline engine has been around for many years and ethanol-petrol has the potential to be used as alternative fuel that can reduce the total CO2 emission from internal petrol engine. However, the changes of bio-petrol is a very complex and need further understanding for researchers due to the relevance of the increase in the petroleum price and the future environmental regulation. The combination between ethanol and petrol provides a new challenging approach to find the good effect to the engines. This study focuses to ascertain a new approach in potential on ethanol-petrol blends operating with a petrol engine especially the effects of ethanol gas petrol blending ratio and variant types of ethanol on performance and emissions of petrol engine. The recommendation of the ethanol petrol fuel blending ratio that strongly affects the vehicles performance and exhaust emissions according to rpm and throttle opening conditions. It is shown that the variant in biopetrol blending ratio and engine operational condition are reduced engine-out emissions and increased efficiency. The ethanol petrol blends had been successfully tested as alternative fuel for spark ignition and the result for engine power slightly increase without engine modification. The result showed that CO2 emissions decreased at high engine speed, while the CO emissions is increases. Thus, process of combustion and stability were increased and engine efficiency was improved with 15% volume ethanol in fuel blend.
