The Effect of Alcohol Blends on the Performance of an Air Cooled Rotary Trochoidal Engine 840237

Results obtained from tests on an air cooled Rotary Trochoidal Engine fuelled with a gasoline-alcohol mixture, without modification of the carburetor, are presented in this paper. The tests were performed with one and two spark plugs. Amongst the obtained results, lower thermal load, better economy and improvement in cycling uniformity when running with two spark plugs were observed. The observed reduction in the rotor housing wall temperature and in the oil sump temperature presents particular advantages for an air cooled engine.
