Directinjection Biogas engine
Research Project , 2012 – 2014

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”
