METHANOL-UNLEADED GASOLINE BLENDS CONTAINING FUSEL OIL FRACTION AS SPARK-IGNITION ENGINE FUEL

In the search for fuel alternatives for spark ignition engines, alcoho l-gasoline blends draw considerable attention. For a successful applic ation of gasoline-methanol mixtures as motor fuel, the realization of a stable homogeneous liquid phase is one of the major problems. In thi s work; phase separation problems of methanol-gasoline mixtures, which were prepared by adding 25% methanol to unleaded gasoline, were solve d by using a fusel oil fraction as the new blending agent. The stable fuel alternatives thus prepared were then tested for fuel properties a nd performance in the engine, and fuel alternatives for the spark igni tion engines were proposed.
