目的有很多农场和拖拉机站还没有制动式马力试验器,在设备不足的情况下,可以采用苏联先进经验,用非制动式马力试验法来检查拖拉机的马力。这一方法不需要复杂的设备,只要有转速表就可以,方法简单,驾驶员很容易掌握。试验时依下列三个程序进行:(1)全部气缸都工作,确定最高空转转速:(2)两个气缸工作,先观察一、二缸,再观察三、四缸:
Purpose Many farms and tractor stations do not yet have a brake horsepower tester. In the case of inadequate equipment, advanced Soviet experience can be used to check the horsepower of the tractor with a non-brake horsepower test. This method does not require complicated equipment, as long as there is a tachometer can, the method is simple, the driver is easy to grasp. The test is carried out according to the following three procedures: (1) All cylinders are working to determine the maximum idle speed: (2) Working on two cylinders, observe first and second cylinders and then observe three and four cylinders:
