Assessment of a VVA system for a diesel HIMCCI combustion engine

This result consists in the application of the VVA technology (currently never applied to a diesel engine) in combination with the innovative diesel engine combustion process HIMCCI (which can provide a significant NOx engine-out emission reduction, as shown during this project, compared to state of the art diesel engines).

With this implementation the HC and CO emission (which are one of the drawbacks of HIMCCI combustion process) can be significantly reduced. It is also possible to increase the exhaust gas temperature, which will help the catalytic after-treatment process.

However, unburned HC and CO emissions are still remaining at a high level, and a particulate trap is in any case necessary to reach very low particulate emission values. Also the noise generated by the combustion has to be put under control during the further developments.
