Simulation studies on the performance of small engine fuelled by methane and the effect of various valve timings
Over the past few years, many researchers have conducted experimental and simulation studies using alternative fuels for internal combustion engine. There are many types of existing alternative fuels can be used in internal combustion engine, but the fundamental information about their combustion pr...

Over the past few years, many researchers have conducted experimental and simulation studies using alternative fuels for internal combustion engine.

This study focus on the performance of methane fuelled engine and optimize it by varying the cam timing angle for both intake and exhaust valves. The engine performance was measured on the brake torque, brake power, brake mean effective pressure (Bmep) and incylinder peak pressure. The engine model was developed based on Modenas Kriss 110cc 4-stroke single cylinder gasoline engine.
