摘　　要：为了研究汽油机的功率、扭矩和燃油消耗率三大性能指标随进气状况的变化规律,开发了小型化、低成本的摩托车发动机可控进气室.可控进气室由空气处理设备、被调空气室、循环风道及控制台组成.控制系统根据温度、相对湿度和压力传感器的信号,利用一个温湿度控制器对制冷系统、加湿器和加热器进行双位控制;利用一个压力控制器,采用PID控制方法对调压风机进行变频控制.通过试验,证明了开发的摩托车发动机可控进气室可以把供给摩托车发动机的气体状态控制在温度5℃～45℃、相对湿度20%～90%及环境压力±15kPa范围内所需要参数的任意组合,并且精度满足台架性能试验的国家标准.To study the influence of admission on power, torque and fuel consumption rate of gasoline engine, a controllable admission chamber for motorcycle motor performance test is developed.The chamber is composed of air proccessor, conditioned air chamber, recirculating duct and console.According to the signals of temperature,relative humidity and pressure transducer control system applies a temperature and humidity controller to control the refrigerating system, the heater and the humidifier in an on-off control mode. A pressure controller is employed to modulate speed of regulating pressure fan in a PID control mode. Experiments proved that the applied chamber controllable admission can make motor intake parameters keep at any specified set point within the temperature of 5 ℃ to 45 ℃, relative humidity of 20% to 90%, and ambient pressure ±15 kPa. And, accuracy can meet national standard for performance test on shelf.
