The possible reasons are as follows ; discharge valve damage or over load operation of diesel engine , or leakage of nozzle , or the incomplete combustion in the cylinder because not enough fresh air was pumped 可能的原因如下；排气阀损坏或柴油机超负荷运转，或油嘴漏泄，或由于进气量不足导致燃烧不完全，等等。
In september 2001 , the department arranged with the electrical and mechanical services department emsd to adjust the fresh air intake and air balance of its air conditioning and ventilation systems in the revenue tower 2001年9月，机电工程署为本局筹划改善税务大楼的空调和抽风系统，调节新鲜空气的进气量和空气平衡状况。
This paper introduces the static control experiment of biogas desulfuration , and quantitative effects of controllable factors on desulfuration , such as reaction time , temperature , total gas input , air input and stuffing , were presented 摘要本文介绍沼气生物脱硫静态对照实验，并对反应时间、反应温度、总进气量、空气量、填料等相关可控因子对脱硫过程的影响进行了定量研究。
The result shows that multiple inlet is better than single inlet , and that inlet with buffer is better than that without buffer . other optimal design structures are also adopted . the gas manifold with optimal structure make oxygen much evener for each cell 结果表明多进口比单进口，有)比无隔板、扩压型进口比非扩压型进口、椭圆台进口比圆台进口的进气箱结构更易实现电池堆中每个单电池进气量的均匀化。
With very large of air intake , gas turbine has more strict desalted requirements , not only for desalting effect but for resistance and size of desalting devices . in this thesis , marine moisture separators used for desalting are simulated numerically and corresponding experimental study are made . thus , we can offer references for design and manufacture of high - powered marine monisture separators 目前国内外有许多大型水面舰船都装备了燃气轮机动力，进气量极大的燃气轮机对进气的除盐要求更为严格，不仅体现在除盐的效果上，同时也对除盐装置的阻力和尺寸等提出较为严格的要求。
