摘要：

The performance optimization of turbocharged common-rail diesel engine was carried out. Taking the China Stage 4 emission standard and less than 5% fuel consumption deterioration as the as the objectives, five combustion boundary parameters, including injection parameters and Exhaust Gas Recirculation (EGR) rate were set for performance optimization on ESC-B speed 50% load rate. Results show the response surface method can determine the key factors that influence the engine performance. The influence of each factor is highly impacted by the specific performance parameter. The interactions among the key factors or between key and minor factors have greater contribution to the engine performance than the interaction among minor factors. Combined with satisfactory degree function, the optimal performance can be accurately estimated, The NOx and soot specific emissions are respectively reduced to 3.43 g· (kW·h)-1 and 0.019 g· (kW·h)-1, while the fuel consumption is slightly higher compared with the prototype. This response surface methodology can be used for engine performance research and development. © 2018, Editorial Board of Jilin University. All right reserved.
