摘要
Abstract
A one-dimensional performance simulation of two-stroke gasoline engine with reed intake valve will be made through an engine performance simulation software GT-Power. Then, the improved schemes will be proposed. The maximum power output point of the prototype is 6 300 r/min, and the actual condition of the highest speed is only 5 500 r/min, that causes the maximum output power waste. By improving the material properties of the reed valve, optimizing the structures of the inlet and exhaust systems and the adjustment of the intake and exhaust ports open timing and other measures , the engine intake and exhaust process of the engine was optimized as well as the output performance. The optimized engine' s highest power-output have risen by 14% at the point of 5 500 r/min, and it is higher 5% than the prototype' s rated power output.关键词
