Abstract
The spark ignition circuit inside an internal combustion engine system is the source which provides the initiation energy required for triggering combustion in a spark ignition (SI) engine in-cylinder air/fuel mixture. Proper spark phasing and adequate spark energy release in spark ignited combustion would yield significant combustion efficiency improvement and affect the in-cylinder production species composition. In this work a simplified spark ignition circuit model constructed based on circuit theorems is proposed. Measurements on how ignition pressure, secondary circuit series resistance and dwell duration would affect the ignition energy migration are presented. Simulations using the proposed model have also demonstrated similar energy migration trends to measurement results which show the influences caused by different secondary series resistance and dwell durations.
