CLOSED-LOOP COMBUSTION CONTROL IN PPCI ENGINE

Dao Nam Cao

Abstract


Low-temperature combustion (LTC) is a method which describes extremely low NOx and soot concentrations in an internal combustion engine. Absolutely, the element that mainly affects to mixture fuel-air premixed and combustion in PPCI engines is chemical kinetics. In PPCI combustion, the pressure, and temperature of the mixture inside the cylinder influence the duration of combustion. This study describes closed-loop combustion control in PPCI engines. Initially, control variables are necessary for this method. Secondly, it considers the combustion feedback sensors and control drives burn. The final section presents the PPCI closed-loop combustion control method.
