This study investigated the effect of some pilot fuel injection parameters, like injection timing, injection pressure and injection quantity on engine performance and exhaust emissions of a supercharged producer gas-diesel dual fuel engine. The engine has been tested to be used as a co-generation engine and its power output is an important matter. Experiments have been done to optimize the injection timing, injection pressure and injection quantity for the maximization of engine power. At constant injection pressures, there is an optimum amount of pilot injection quantity for that maximum engine power is developed without knocking and within the limit of maximum cylinder pressure. Above or below of that amount engine power is decreased. Higher injection pressures generally show better results than lower ones. However, good results can also be obtained with lower injection pressure, if maximum power timings can be selected. Two-stage combustion is obtained as a mentionable fact which is an indicator of maximum power output conditions as well as a precursor of knocking combustion. Smoke is found almost zero throughout the experiments and hydrocarbons (HC) are very low. However, carbon monoxide (CO) level at all experimental conditions is very high. Nitrogen oxides (NOx) at maximum power conditions are also very high. These need to be reduced.
