Numerical study of engine parameters on combustion and performance characteristics in an n-heptane fueled HCCI engine

Homogeneous charge compression ignition (HCCI) is an alternative combustion concept which offers significant benefits in terms of its high efficiency. However, the operational range using HCCI combustion in terms of speed and load is restricted due to the absence of the direct control of the onset o...
