Researches were performed using a three-cylinder a direct injection diesel engine. Fuel E85 was supplied to the engine, by injection into the intake system. An analysis of thermodynamic parameters of such engine was conducted. With E85 fuel participation, NO x, CO and soot emissions were reduced, whereas THC emission increased. It can be explained that some ethanol is trapped inside the crevice resulting in increased HC emissions. The share of E85 can effectively reduce soot emission. The reductions are due to the reduction of diesel fuel consumed as well as the increase in fraction of heat release in the premixed phase of combustion. Consistent with other studies, the soot emissions were largely dependent on oxygen content in the fuel. Key words: engine piston engine, dual, bioethanol, combustion, emission Bibliografia 1.
