Directinjection Biogas engine

The use of gaseous fuels in internal combustion engines will almost certainly increase in the future. The goal of this project is to evaluate different concepts with direct-injected gas (DI) that can operate with various mixtures of biogas / natural gas and hydrogen. Today there are no direct injection SI gas engines, but a shift in technology to direct injection is expected to lead to significant improvement in efficiency and reduced emissions with greater fuel flexibility (up to 100 % hydrogen). The project will also deal with dual-fuel combustion in CI-engines and the validation of a previously developed combustion model for 3-D CFD simulations. The project is connected to the IEA’s “Collaborative Task on Alternative Fuels in Combustion”
