Abstract
In conventional internal combustion (IC) engines, the compression ratio is fixed. One Basic problem is that drive units in the vehicles must successfully drive at varying speeds and loads and in different weather. If a diesel engine has a fixed compression ratio, a minimum value must be selected that can obtain a true self-ignition when starting the engine in cold start conditions. The combustion process in the internal combustion engine is changing cycle to cycle while changing load, speed, etc. It is difficult to obtain good fuel economy and decrease pollution emissions Palm oil/palm oil methyl esters are blends with diesel fuel; the blends were characterized as an alternative fuels for diesel engines. Density, kinematic viscosity, and flash point were estimated according to ASTM as key fuel properties. This paper aims to optimise the levels of such parameters as compression ratio (CR), injection pres- sure (IP) and palm oil biodiesel blend % of a single cylinder direct injection compression ignition engine on carbon monoxide (CO), hydrocarbon (HC) and nitrogen oxide (NOx) emissions. Taguchi and Analysis of Variance techniques were used to find the optimum levels of the parameters and contribution of the parameters on the emission, respectively. Confirmation tests were performed for predicting the gas emissions to check the adequacy of the proposed model.
