The disposal of the valves and intake manifold structure not only affect fresh air charge but airflow in the cylinder, which immediately affect combustion efficiency and the performance of dynamic, economic and emission. the structure of the air distributing institution has influence on charging efficiency and the noise of engine. the combustion chamber affects compression scale which has great influence on dynamical performance ; f / v which affects the exhaust of hc ; squash area and clearance which have great influence on the intensity of squash
氣缸蓋的氣門排列方式與氣道結構形式影響進氣充量和氣流在氣缸內的運動，從而影響了燃燒效率，對整機的動力性、經濟性以及排放都有直接的影響；配氣機構的形式影響充氣系數和整機噪聲等；缸蓋燃燒室決定了影響整機動力性能的壓縮比，影響hc排放的f / v和對擠流起決定性作用的擠氣面積以及擠氣間隙，所以燃燒室對整機動力性、經濟性、排放等都有重要的影響；氣缸蓋是整機熱負荷與熱應力最大的部件之一，熱負荷過高將不利於發動機壽命以及可靠性的提高。 -
By comparing the results of two different lengths of xiaofang, it is found that the combustion efficiency with a smaller length is higher. moreover, the effect of various structure, such as the lengths of dafang, the angle between xiaofang and dafang is analyzed with a 2d model. the results show that the combustion chamber with smaller angle and length of dafang is better
通過對不同小方段高度燃燒室計算結果的比較，發現適當的減小小方高度將有助於提高燃燒效率;另外，還針對不同結構參數下的燃燒室二維流場進行了模擬，結果表明在一定范圍內增大突擴角和大方段高度可以使燃燒進行得更充分。
