Comparison of fuel consumption and emission of small two-stroke engine of electric generator fuelled by methanol, biogas, and mixed methanol-biogas

A two-stroke engine run with flexible fuel of biogas or methanol is not established yet. It the objective this work to provide 2 stroke for an electric generator that can be by using fuels namely: methanol, biogas, and mixed methanol-biogas. small single cylinder was set able fuelled 3 different types namely (50% vol. CH4, 15% CO2, 0 ppm H2S), (CH3OH) 97% purity biogas-methanol. The used providing 750-watt electricity. compression pressure around 10 Bar volume 63 cc. easy switch system fuel. Since as one type used, then special lubricant should prepared purpose. generally known commercial synthetic usually gasoline 2-stroke engines found well methanol. castor oil selected a ratio 50:1. During only fuel, dripped drops/minute in biogas-air mixer chamber. emission, consumption, were investigated both idle position loaded at 200 watts. consumption 18.83 L/minute increases become 15, 17 load By 0.009 0.011 during loading If applied becomes 2.06L/minute 4.43 lowest CO emission 0.18 % vol., followed biogas+ 0.26% highest 0.25%vol. watts, same 0.18% + volume, worst 0.33
