Abstract:
We propose a model-based control strategy to adapt the injection settings according to the air-path dynamics on a diesel HCCI engine. This approach complements existing air-path and fuel-path controllers, and aims at accurately controlling the start of combustion. For that purpose, start of injection is adjusted based on a Knock Integral Model and intake manifold conditions. Experimental results are presented, which stress the relevance of the approach.
