The exhaust gas composition of several potential greenhouse gas neutral C1-based synthetic fuels and gasoline/alkylate-blends are compared to each other and benchmarked against gasoline. The search for sustainable alternatives to conventional fossil fuels is still ongoing. Ideally, the exhaust gas of such an alternative should not deteriorate the environment’s air quality. The testing conducted here is focused on automotive application. However, promising fuel candidates could also be used elsewhere. The gasoline/alkylate blends investigated contain various percentages of dimethyl carbonate (DMC) or methyl formate (MeFo). Various methanol-MeFo mixtures as well as a 65 vol% DMC+ 35 vol% MeFo mixture are investigated as examples for a pure synthetic fuel. The tests are carried out on a single-cylinder spark ignition research engine.
