与此同时，内燃机的排气污染是环境保护中的一大难题，而它与燃料品质有着密切关系。
At the same time, exhaust pollution of internal combustion engine is a big issue on the environment protection, which is directly related with quality of the fuel.
从技术上讲，化学燃料火箭的最大速度增长比较低。这就是说，它们的排气速度还不足以将火箭的速度增加到非常快的程度。
In technical terms, chemical rockets have low maximum velocity growth, which means that their exhaust velocities are not high enough to impart very high speeds to the rocket.
时常由于作为临时原料气的燃料气入口压力低造成燃料气压缩机由于排气高温而停机。
The temporary raw material gas is used to do the fuel gas, so the fuel gas compressor often appears that its suction pressure is low to result in the fuel gas compressor is shut down.
