Determining the impact of diesel exhaust emissions on human health and the environment requires evaluating both regulated and unregulated properties of exhaust gas. In particular, emissions from new fuels have to be examined thoroughly to prevent any impact from increased emissions of harmful substances. In addition, identifying and utilizing new alternative fuels to replace fossil fuels is an important task now and in the future. This study investigates the influences of properties of RME 100%, RME-diesel blends of different ratios, ethanol-diesel blends with low amounts of ethanol and gas-to-liquid and its blends on thermodynamic properties and emissions, specifically their impacts on cylinder pressure levels.To this end, different variables are combined e.g. with different EGR rates, EGR temperatures and injection timing. The results obtained are used to evaluate and optimize the engine s operating process with exhaust gas recirculation and different alternative fuels and their blends with conventional fuels.
