Abstract
HCCI engines take advantage of high compression ratio and heat release rate, they exhibit high efficiency in compression ignition engines HCCI engines also utilize a lean air/fuel ratio resulting in low emissions of NOx and particulate matter(PM), The objective of this research is to determine the effects of EGR rate on the combustion processes of HCCI For this purpose, a 4-cylinder, compression Ignition engine was converted into a HCCI engine, and a heating device was Installed to raise the temperature of the intake air and also to make It more consistent In addition, a pressure sensor was inserted into each of the cylinders to investigate the differences m characteristics among the cylinders
