Abstract

Opposed-Piston Two-Stroke (OP2S) diesel engines have been successfully used in many applications because of its high power efficiency. Uniform scavenging is used on OP2S diesel engines. Different from conventional diesel engine exchanging systems, intake ports and exhaust ports are located at each sides of the cylinder as OP2S scavenging system. A scavenging system optimization method, Genetic Algorithm-Support Vector Machine (GA-SVM), which employs Indicated Mean Effective Pressure (IMEP) as optimization goal is presented. The combinations of five key parameters including the width and length of intake and exhaust ports and the crank asymmetric angle are designed. All these combinations are calculated by GT-Power. The predicting model of OP2S diesel engine`s IMEP is built based on the 1D results. After verifying the accuracy of the predicting model, the optimized parameters are found. The results illustrate: using 1-D simulation coupled GA-SVM to optimize scavenging parameters in OP2S diesel engines is a rapid and effective method. The optimized IMEP is 12.86 bar. This paper presents some guidelines in the further OP2S diesel engines research.
