Abstract: | ||
| A Design of experiments methodology was carried
out to investigate the effects of the compression ratio, cylinder head
material, and fuel composition, on the engine speed, fuel
consumption, warm-up time, and emissions of a carbureted single
cylinder air-cooled spark ignited engine. The work presented here
is aimed at finding out the sensitivity of engine responses, as well as
the optimal combination between the abovementioned parameters.
Engine performance was evaluated based on the changes in engine
speed at idle conditions. Regarding the exhaust gas emissions, the
concentrations of CO2, CO, and HC were recorded.
