The increasing requirements for reduction of the traffic related emissions have attracted great interest with regard to the development of alternative fuels concepts. Due to the potential availability and because of the expected better environmental benefits, methanol is increasingly being considered as a promising replacement for mineral oil based fuels. DI methanol engine concepts with supercharging and aftercooling are of special interest because of their particular beneficial fuel consumption behavior. Neat methanol concepts on the basis of forced ignition concepts, such as the hot surface ignition (HSI) and the spark ignition (SI) show a good potential to achieve very low exhaust emissions, due to soot free and low particulate engine operation as well as a considerably low level of NOx emissions. Already at the current status of development, the DI HSI methanol concept, equipped with an exhaust gas recirculation system and an oxidation catalyst, shows encouraging results to keep within the future California emissions standards. The spark ignition concept has not been developed so far, that a final assessment can be conducted. Advantages for the DI SI concept can be seen in the more favourable acoustic behavior of the engine and in the potential benefit for this concept with regard to flexible fuel operation.
