Behaviour of methanol/gasoline injection in spark ignition engines

Spark ignition engines are the dominant prime mover in passenger vehicles today, and this will remain the case for decades to come whilst the vehicle fleet evolves towards greater hybridization and electrification. It is well known that increasing fuel octane enables lower greenhouse gas emissions from spark ignition engines, and that direct injection in spark ignition (SI) engines is now commonplace. However, it is less well known that the addition of methanol to gasoline can enable very substantial octane boost, and that zero emission methanol can be made using renewable energy.

Despite these trends, modelling fuel injection and combustion remains a major challenge for engine and fuel designers, particularly with alternative fuels such as methanol. This project will therefore first undertake a detailed experimental study of the direct injection of different gasoline/methanol mixtures in a Constant Volume Chamber (CVC). High Performance Computation using Large Eddy Simulations (LES) will then be validated using these experiments.
