Abstract
Homogeneous Charge Compression Ignition (HCCI) engine has the potential to achieve lower NOx and PM emissions with high thermal efficiency. Although it has these merits, operation region is still limited by knocking. Combustion phasing retard is one of the methods to avoid knocking. However, excessive retard of CA50 will lead to unstable combustion. In this study, we developed a combustion control system for HCCI engine fuelled with DME. The cyclic dispersion mechanism on the excessive retard of CA50 was analyzed. And the controlling road map for reducing combustion variations was obtained. Based on these results, reduction of cyclic dispersion is realized by combustion control.
