In this paper, we propose a control strategy to improve stability of the combustion of HCCI engines during sharp transients. This approach complements existing airpath and fuelpath controllers, and aims at accurately controlling the end of the cool flame phenomenon. For this purpose, injection time is adjusted based on an auto ignition model and a cool flame model. Experimental results are presented, which stress the relevance of the approach.
