Abstract

Compression period in a diesel engine is generally seen as initial characteristics before injection into combustion chamber. The piston moves freely in a rapid compression machine (RCM) has been designed to simulated combustion phenomena to observe the physical and chemical kinetics studies at high pressures and temperatures. The purpose of this study was to clarify the effect of the cylinder wall temperature on the heat release of air, particularly during compression. This method is done with a lighter piston launcher by nitrogen bomb and will stop at the stopper. Tests performed on a light weight compression piston rapid compression machine (RCM) with the aim to simulate the actual compression associated with the phenomenon of combustion. During this phenomenon, the influence of the ambient temperature of the cylinder wall has appeared useful to start biodiesel fuel blend and achieve the best premixing. The test will three times to investigate the effects of different temperatures on the cylinder walls during compression stroke. The results show that high temperature in the cylinder wall will affect the current drop in temperature after the compression stroke. After analyse, new features rapid compression machine will produce to develop and analyses for ignition delay and image of sprays.
