The effect of ringing combustion on the wall heat flux during HCCI operation

Abstract
Homogeneous charge compression ignition (HCCI) engines are a promising alternative to spark- and compression-ignition engines, due to their high thermal efficiency and near-zero emissions of NOx and soot. However, the maximum achievable load is limited by the occurrence of a ringing combustion. The rapid release of energy leads to pressure waves in the combustion chamber that cause a knocking sound and possible engine damage. In this work, the effect of a ringing combustion on the heat transfer is investigated. The heat flux is measured in a CFR engine under both normal and ringing combustion. It is found that the heat transfer increases when ringing occurs. This can be attributed to the increased gas motion caused by the pressure waves.
