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 ...

Implementation of thermal and fuel stratification strategies to extend the load limit of HCCI engine

Journal of Thermal Science and Technology, 2019
The HCCI engine can be a possible potential engine technology that gives high performance with fewer dangerous exhaust emissions. In HCCI engines, low-temperature combustion of lean, highly premixed charge effectively reduces the NOX and soot.
