Abstract

A method to deliver spark during a start for an internal combustion engine is described. The method provides individual cylinder spark angle control based on the number of cylinders after synchronization between engine timing and an engine controller are achieved. The method offers improved engine emissions while maintaining engine speed run-up performance.
