The success of stratified combustion is strongly determined by the injection and ignition system used. A large temporal and spatial variation of the main parameters - mixture composition and charge motion - in the vicinity of the spark location are driving the demands for significantly improved ignition systems. Besides the requirements for conventional homogeneous combustion systems higher ignition energy and breakdown voltage capability is needed. The spark location or spark plug gap itself has to be open and well accessible for the mixture to allow a successful flame kernel formation and growth into the stratified mixture regime, while being insensitive to potential interaction with liquid fuel droplets or even fuel film. For this purpose several different ignition concepts are currently being developed.The present article will give an ignition system overview for stratified combustion within Delphi Powertrain Systems. In addition to conventional high energy systems, MultiCharge systems and their derivatives as well as more sophisticated advanced concepts are presented. Their potential for stratified systems is assessed in view of sometimes contradicting requirements like energy level vs. electrode erosion.
