Abstract
This study investigated the effect of injection pressure and injection quantity for pilot fuel on engine performance and exhaust emissions of a supercharged producer gas-diesel dual fuel engine. Injection pressure of 80 MPa with the injection quantity of 3 mg/cycle showed the best results. Effect of hydrogen (H_2) content in producer gas on engine performance and emissions is also investigated with two types of producer gases with varying H_2 content with the optimum injection pressure-quantity condition. Experimental strategy was to optimize the injection timing for the maximization of engine power at different fuel-air equivalence ratios without knocking and within the limit of maximum cylinder pressure. Better combustion, engine performance and exhaust emissions (except NOx) are obtained with the high H_2 content producer gas than that with standard producer gas, especially at leaner conditions. Moreover, a broader window of equivalence ratio is found with highest thermal efficiencies with the high H_2 content producer gas.
