intake pressure meaning in Chinese

进口压力
进气压力
吸气压力
吸入压力

During the steady state of intake test , when intake pressure is over about 20 . 4kpa , the vacuum pump does n ' t work properly , because this pressure is over the normal range of it , but the turbo diesel engine ' s operating conditions are larger than that of it . so we use the 3 - d calculation results instead of test for the next calculation
而对于增压柴油机在正常工况下的进气压力均在20 . 4kpa以上，故在这种情况下利用三维数值计算值来代替试验，作为试验的一种补充，为进一步研究变工况的进气过程提供依据。
The paper researches the motorcycle ' s administrative system microems , which provide the experimental support of the injection and the ignition advance angel . it is very difficult to measure quite high exact value of atmospheric pressure . this paper introduces a new mathematic model that aims to obtain the intake pressure and the injection fuel of the engine cycle
本文对摩托车汽油机管理系统microems的组成与功能进行了研究,为电控摩托车发动机喷油及点火控制建模与仿真提供了实验硬件支持,同时也为主要参数进行测量和数学建模提供理论依据。
