Abstract:
Method of operating a compression engine on a dimethylether containing fuel obtained by conversion of methanol primary fuel, comprising the steps of:(a) pressurizing the primary methanol fuel in its liquid form to a final engine injection pressure; (b) preheating the pressurized primary fuel by heat contained in engine exhaust gas; (c) introducing the primary fuel to a reactor and converting the primary fuel at injection temperature of the engine and the injection pressure to the dimethylether containing fuel by contact with a methanol dehydration catalyst in the reactor; (d) withdrawing the dimethylether containing fuel from the reactor; and (e) injecting the dimethylether containing fuel as produced in the reactor at the injection pressure and temperature as the sole fuel directly into the engine.
