Summary

This paper describes the demands and potentials of today´s and future gasoline combustion systems regarding the fuels gasoline, natural gas and hydrogen. At first, fuel specifications that are crucial for the spark ignition process are compared. These are compared with the requirements given by the combustion system. Potentials for the compensation of power loss, efficiency improvement and emission reduction using alternative fuels are discussed taking into account fuel-specific properties. While full load drawbacks with natural gas compared with gasoline can be reduced to less than 5% by combustion system tuning, hydrogen operation with port injection leads to reductions of about 25-30%. These drawbacks can be compensated with boosting where both methane and hydrogen are qualified due to their burning characteristics.
