For intake system , adopting the resonant intake manifold construction , make use of the intake motive effect to increase volumetric efficiency ; adopt measure to prevent the heat transmit between intake pipe and exhaust pipe , lower the intake air temperature to increase volumetric efficiency 对于进气系统，采取谐振进气的结构措施，利用进气动力效应来提高进气充量；采取进、排气管隔热措施，降低进气温度来提高进气充量。
On the basis mentioned above , another mathematical model for the supercharged diesel was set up . according to this model some results of simulation calculations were given . the characteristics of operation of the diesel in wet compression : including the excess air coefficient , the cylinder temperature at the beginning of compression stroke , the maximum temperature in the cylinder , the cylinder thermal load , the specific fuel consumption , and efficiency of diesel engine were obtained 在此基础上，又建立了增压柴油机湿压缩的数学模型，对喷水后柴油机的各性能参数，诸如过量空气系数、气缸进气温度，缸内最高温度、气缸热负荷、比油耗、热效率等进行了仿真计算，为增压柴油机进口加湿技术的研究提供了理论依据。
The engine is tested on the dynometer using the software that can monitor the ecu ( electronic control unit ) internal dataflow . and the electronic control fuel injection system parameters ( e . g . position of throttle valve , engine speed , air temperature , engine temperature , duration of injection ) are acquired at many different working conditions of engine 本文以hirth3203二冲程汽油发动机为研究对象,利用开发的ecu内部动态数据流监测软件进行发动机台架试验,获取了在不同的油门开度和转速下电控燃油喷射系统的一系列工作参数,如节气门开度、发动机转速、进气温度、气缸温度、蓄电池电压以及喷油脉宽。
