Combination of multiple combustion modes in a gas engine system using dedicated EGR
Nihon Kikai Gakkai ronbunshu, 2019 Although HCCI combustion has high thermal efficiency, it has difficulties such as controlling its ignition timing and combustion. This study proposed a method to make HCCI combustion in gas engines possible, combining dedicated EGR, SI combustion, and ...

Modeling of HCCI engine combustion for control analysis [PDF]
2004 43rd IEEE Conference on Decision and Control (CDC) (IEEE Cat. No.04CH37601), 2004 Operation of homogeneous charge compression ignition (HCCI) engines are very sensitive to timing variations in the combustion of the air-fuel charge mixture and require precise control of the ignition instant to run properly. It is therefore essential to understand the characteristics of timing variations under various operating conditions in order to ...
