We propose a model-based control strategy to adapt the injection settings according to the airpath dynamics of a conventional Diesel engine. This approach complements existing airpath and fuelpath controllers, and aims at accurately controlling the middle of combustion. For that purpose, start of injection is adjusted based on a combustion model and intake manifold conditions. In particular, no in-cylinder sensor is used. Simulation results are presented, which stress the relevance of the approach.
