在美国考察各著名拖拉机制造公司和几所大学的农业工程系实验室时,我们注意到他们在进行拖拉机和柴油机试验时所用的测试设备。我们觉得:从总的来说,测量燃油消耗所用的测量原理和方法和目前我国国内的相仿。就是说:在室内试验台上,无论是发动机台架试验或动力输出试验一般都是用重量法,并采用天平来秤重,即测出消耗一定重量的燃油所经 When we visited the well-known tractor manufacturing companies and agro-engineering laboratories at several universities in the United States, we noticed the test equipment they used to carry out tractor and diesel tests. We think: In general, the measurement principle and method used to measure fuel consumption are similar to those in our country at present. That is to say: In the indoor test stand, either the engine bench test or power output test are generally used gravimetric method, and the balance to weigh, that is measured by the consumption of a certain weight of the fuel
