Fuel Flexible Engine Platform (FLEX I)

Research Project, 2015 – 2017

The utilisation of alternative fuels is made possible by providing a truck engine with new components. Injector adapted for fuels with low viscosity and with high volatility. Different types of ignition systems will be evaluated and demonstrated to handle high-octane fuels. Cylinder head and combustion geometry will be modified to handle two separate injectors. The engine will be able to operate in different combustion modes, which allows optimising the efficiency, emissions and fraction of alternative fuel dependent on load and speed. The high degree of flexibility gives the engine a potential for higher efficiency than is possible using only diesel. The project will also lead to increased fundamental understanding of fuel properties and its effect on combustion, through systematic studies spray, engine tests and improved simulation models. The project is planned with 3 years duration with Volvo as main applicant and Chalmers and Loge as partners
