| 1. | A nearly constant air-fuel ratio is maintained by the main metering system from part-to-wide-open throttle .
从节气门部分开启到全部开启，主计量系统保证了空燃混合比几乎恒定。 |
| 2. | They varied both chamber pressure and mixture ratio, making use of a stepfunction change in the oxidizer injection rate .
他们通过用氧化剂喷射速率阶跃函数变化的方法来改变气室压力和混合比。 |
| 3. | For firing of the mixture in the cylinder every time spark occurs, the air-fuel ratio must lie in a fairly narrow range .
为了在气缸里每一时刻发生一次火花时混合气的燃烧更理想，空一燃混合比必须限于相当狭窄的区域内。 |
| 4. | 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。 |
