Fuel stratification to enable higher load operation in homogeneous charge compression ignition engines

The project will contribute fundamental knowledge towards the development of the clean and highly efficient homogeneous charge compression ignition engine concept. We aim to reduce problematic high rates of heat release at high load that are a crucial factor preventing the commercialisation of these engines. We will use fuel stratification to avoid the simultaneous ignition of the entire charge and reduce the rate of heat release. The use of renewable fuels will lead to further emissions reductions. Combining advanced modelling with experiments in optically accessible engines will enable the fundamentals of stratified ignition to be studied and understood as well as guiding the search for the optimal fuel stratification approach.
