单缸大排量发动机性能实验与优化设计

Test and Optimized Design in the Big Displacement Motorcycle Engine Performance

利用实验进行优化设计是现代设计方法之一。介绍了从进气晚关角,进、排气的动态效应几方面实验着手, 不断改进发动机的配气相位以及进、排气系统,使发动机的实际性能曲线逐步接近计算机仿真曲线。

Optimized design with the test results is one of the modem design methods. This paper introduces the optimized intake lag angle of the engine, application of dynamic effects of intake pipes and exhaust pipes, improvement of motorcycle engines, which make the practical performance curve approach gradually the simulation curve.
