Effect of Methanol Blends on performance of Two Stroke petrol Engine at varying load conditions

DOI: 10.22161/ijeab.92.28

Abstract:
Experiments were conducted to evaluate the performance evaluation of two stroke single cylinder, spark ignition (SI) engine, with methanol blended gasoline (40% gasoline, 20% methanol, & 10 % by volume). Performance parameters (brake horse power, specific energy consumption, thermal efficiency,) were determined at varying load condition it is observed that The experiments shows that 10% methanol blend with gasoline gives the best performance for the SI engine. The power output of the engine is almost near about the petrol on blend M10. It is recorded that the higher power output is 2. 85 KW with M10 blends at load 8 Kg as compare to petrol and the lowest power output is from the engine is 0. 82 KW with blend M40 at load 2 Kg. The specific fuel consumption decrease as load increase for petrol and methanol blends. The SFC of methanol (M10) is higher at low load condition and low at high load conditions as compare to other blends.

Keywords:
Gasoline, Methanol, specific fuel consumption. Brake horse power, Brake thermal efficiency, Engine.
