摘要
利用相关发动机参数,通过GT-Power仿真软件建立OED483Q可变截面涡轮增压柴油发动机的整机模型,并利用试验数据对模型的主要参数进行验证和校准。在此基础上,结合试验对柴油机OED483Q的推进特性进行研究及分析,比较可变截面涡轮增压与普通废气涡轮增压对柴油机的不同影响。研究结果表明:采用可变截面涡轮增压可有效提高低负荷增压压力,降低有效燃油消耗率,提高经济性;同时,能避免增压压力过大导致的涡轮前排气温度过高,保证发动机的正常使用寿命。
A complete model of OED483Q variable geometry turbo-charge diesel engine is established with GT-Power simulation software based on the relative engine parameters.The main parameters are validated and calibrated in the model experiment.On this basis,the propulsion characteristics of the OED483Q diesel engine are studied and analyzed along with the experiments,and the effects of Variable Geometry Turbo-charge(VGT)and ordinary waste gas turbo-charge on the diesel engine are compared.The result shows that variable geometry turbo-charge can effectively increase the pressure under low loadings to reduce effective fuel consumption rate and to increase economic benefit.Moreover,it can avoid the overheating of the exhaust gas from the turbo-charge due to the excessive pressure,and thus to guarantee the operation life of engine.
