2、发动机台架试验发动机台架试验是目前采用得最广泛的试验方式,主要包括启动试验、怠速试验、无负荷试验、部分负荷试验、全负荷性能试验启动试验分低温(-10度)和常温(20度)两种,由于一般主机厂都不具备低温启动试验的条件,常温启动试验成为广泛采用的方法。有点要说明的是,有人常常误解为只在低温启动时才允许使用阻风门,其实 2, engine bench test Engine bench test is the most widely used test methods, including start-up test, idle test, no-load test, partial load test, full load performance test start test sub-temperature Normal temperature (20 degrees) two, as the general OEM do not have the conditions for low temperature start-up test, start testing at room temperature has become a widely used method. It is a bit to be noted that some people often misunderstand that it is only allowed to use the choke only when starting at a low temperature. Actually,
