In the course of the early rig tests it was observed that, within limits, combustion efficiency was largely independent of the size of the fuel jet . 在早期的试验器试验时,已经发现在一定权限范围之内,燃油喷注的大小对燃烧效率影响很小。
For design calculations, it is usually adequate to use the theoretical value for the approximate mixture ratio, corrected by a typical combustion efficiency factor . 对于设计计算,采用相应混合比的理论值,并用典型的燃烧效率系数来修正,通常这样做是恰当的。
