Irrespective of disconnection of a fan , control of the exhaust steam pressure , must be maintained 必须保持风机不被无端的断开,排气压力在控制之下。
If keeping compressor ' s rotating speed unchanged , wet compression can increase compressor discharge pressure and lower exit temperature at the same time 在保持压气机转速一定情况下,压气机排气压力升高,与此同时排气温度下降。
An experimental study is carried out on the effect of following factors on the combustion performance of a vehicle fuel heater : geometric parameters ( the number , diameter , distribution and direction of combustion chamber intake holes ) and intake and exhaust pressures 摘要对车用燃油加热器燃烧室进气孔径(流通面积) 、孔的分布、孔的方向等几何参数和进排气压力对加热器燃烧性能的影响进行了试验研究。
To analyze the pressure waves in the exhaust pipes and the influence of the catalytic converter , new simulation software has been developed by the author on the base of mk14 , which is a powerful tool in developing exhaust system with catalytic converter . its principle and the method to use are explained . the numeral models for engine simulation are simplified in the paper 为分析摩托车排气压力波的构成与变化、也为分析催化转化器在排气系统中对整体设计的影响,借鉴目前常用的几种模拟计算软件,结合特征线理论,在mk14程序的基础上开发了以进、排气系统为主的发动机模拟计算系统( escs ) ,该程序是加快设计周期的有力工具。
A model of letting out of no oil ubricated double whirlpools vortex air compressor was set up , the length of leak line of one cycle was calculated the change of the leak line at work , the change of the length of leak line varying with the crank corner , and the change of the leak amount varying with the pressure of revealing atmospheric and crank corner were analyzed 摘要建立了无油润滑双涡圈涡旋压缩机的泄露模型,根据型线的几何理论计算了一个周期内泄漏线的长度,分析了在工作过程中泄漏线的变化,泄漏线长度随曲柄转角的变化,以及泄露量随排气压力,曲柄转角的变代情况。
