| Abstract:A simplified one dimensional model was built by the GT-Power for the two-stroke linear engine of a linear integrated starter generator (ISG) power system. The key structural parameters of the engine scavenging system, specific time-area values of scavenge and exhaust as well as the volume of scavenging box, were simulated and optimized in order to improve scavenging quality and the linear engine performance. Results show that the scavenging efficiency of the optimized linear engine reaches 88.15% and the capture ratio 59.38%, 1.58% and 28.81% higher than those of the original respectively, the power performance and fuel economy are both obviously improved as well. |
