| Abstract: | In this paper, a single-cylinder direct-injection diesel engine simulation model is established with GT-POWER. It takes advantages of GT-POWER control module by adjusting the coefficient of the proport!on,integration and differentiation to control engine in conditions of stable operating. In addition, the engine emissions performance is analyzed and a parameter optimization options is conducted by changing injection timing and injector nozzle hole aspect ration. |
