combustion expansion ratio

基本解释

With the increasing of pressure of gas generator under less injector number and expansion ratio, combustion efficiency increase.
在噴嘴數目較少和擴張比較小時，增加燃氣發生器工作壓強補燃傚率增加。
The effect of inlet size, inlet angle, dome height, primary nozzle expansion ratio and nozzle numbers on combustion efficiency were taken into account.
考慮了進氣道尺寸、進氣夾角、頭部距離、一次噴嘴擴張比和噴嘴數目等結搆因素對補燃室摻混與燃燒性能的影響。
Note that the compression ratios shown above reflect the expansion ratio, which is the ratio of the combustion chamber volumes when the piston is at Bottom dead centre and Top dead centre.
請注意，壓縮比上述反映膨脹率，這是燃燒室的量的比例時，活塞的下死頂死中心，中心會顯示。
