Abstract
This study investigated the effect of the ignition positions in a two-point ignition system on homogeneous charge compression ignition (HCCI) combustion. Focus was put on controlling the ignition timing, and changes in combustion behavior due to the ignition positions were observed on the basis of in-cylinder combustion visualization and pressure analysis. Experimental results showed that misfire occurred under a condition where the temperature rise time was short and combustion became unstable. In contrast, combustion was stable under a condition where the rise time was sufficiently long and autoignition developed along the cylinder wall. As a result, knocking intensity was reduced by stable combustion.
