Towards clean diesel engine combustion: Fuel formulation and mixing strategy for rate of heat control with premixed (stratified) charge compression ignition combustion (07911)

Project nummer: 07911

Omschrijving van het onderzoek

Premixed charge compression ignition (or PCCI) is a new combustion concept that promises very low emissions of nitrogen oxides and of particulate matter by internal combustion engines. In the PCCI combustion mode fuel, products from previous combustion events and air are mixed and compressed until the resulting mixture locally auto-ignites. Auto-ignition at other places in the reacting mixture follows rapidly and combustion takes places across the combustion chamber within a short period. A major challenge with PCCI combustion is the accurate control of the start of combustion and of the rate of heat release during combustion.
PCCI is considered by the automotive industry as one of the most interesting innovations to the internal combustion engine. PCCI engines are expected to match the almost zero emission levels of current best-in-class gasoline engines (these are the engines powering the so-called Super Ultra Low Emission Vehicles) while maintaining the high thermal efficiency typical of current diesel engines. The fundamental knowledge gained in this project will lead to improved models and new experimental diagnostics that can be the basis for breakthroughs in engine design and control for PCCI application and for the definition of new dedicated fuels that match with this combustion concept.
