THE EFFECTS OF ALCOHOL ADDITION TO FUEL ON PISTON WEAR IN A TWO-STROKE ENGINE

Abstract

In this study, the effects of 20% methanol (BM20) and ethanol (BE20) addition to the fuel of a motor scythe with a two-stroke gasoline engine, which is also used as a hand tool, were examined. The effects of adding alcohol to gasoline on fuel consumption value, the amount of deluge release on the piston, piston overflows and exhaust emissions were investigated. The motor scythe was operated for 50 hours and 100 hours to investigate the amount of wear. With the addition of methanol and ethanol, it was determined that the fuel consumption value and wear increased and the amount of hallucinations decreased compared to gasoline. In terms of emission values, reduction in CO and HC emissions with alcohol use, reduction in CO2 emissions with BM20 fuel mixture, increase with BE20 fuel mixture was determined.
