Propane Fumigation in a Direct Injection Type Diesel Engine 831354

An experimental study was conducted to evaluate the use of propane and natural gas as fuels for diesel engines. Experiments were conducted by injecting different quantities of pilot diesel fuel at a fixed injection timing. The amount of pilot quantity was found to influence the engine performance, particularly at low loads. The engine thermal efficiency, emissions and noise were found to depend on the overall equivalence ratio as well as on the quantity of pilot injection.
