The Homogeneous Charge Compression Ignition (HCCI) engine has attracted considerable interest in recent years as a new combustion concept for internal combustion engines. The HCCI engine has three major advantages: low fuel consumption, low carbon dioxide (CO_2) emissions and low nitrogen oxide (NOx) emissions. However, the HCCI combustion process has four issues: ignition timing delay, slower combustion reaction speed (maximum heat release rate), difficulty in expanding stable operation to the high load region and avoidance of knocking. In this study, we used a primary reference fuel (40 RON) as the test fuel and tried to overcome these issues by applying internal and external exhaust gas recirculation (EGR). We varied the internal and external EGR rates and examined their respective influence on HCCI combustion.
