A full-engine-cycle multidimensional model was applied to investigate the effect of late (intake valve closing) IVC on combustion and emission characteristics in a diesel (premixed charge compression ignition) PCCI engine in a wide speed and load range. The results indicate that the in-cylinder...

The environmental impact of automotive transport systems and the need for reducing petroleum dependence lead to the development of alternative combustion strategies and the use of renewable fuels. In this work, HCCI combustion mode, by using ethanol as fuel, is analysed in order to clarify the...
