The tractor should not run too long at low speed
with high accuracy and repeatability; The truth is that the atomization quality of the fuel injector is mainly related to the question answering power of the fuel injection pressure tester, the diameter of the fuel injector and the speed of the camshaft. Since the fuel injection aperture has been fixed, the atomization quality of the diesel engine LS10 saves the shape of the mixing chamber of FPL, which depends on the fuel injection nozzle pressure and cam speed. The higher the fuel injection nozzle pressure is, the faster the camshaft speed is, and the better the fuel injection atomization is. While the camshaft speed changes with the crankshaft speed. When the diesel engine speed is lower than the rated speed, the atomization quality of the fuel injection nozzle presents a supersaturated state, A long time will lead to abnormal operation of the diesel engine. When the diesel engine is overloaded, the temperature of the engine body will rise, which will raise the temperature of the engine oil, resulting in the most comprehensive output. As a result, the low-speed oil supply of the oil pump is insufficient, which will lead to poor lubrication of all mating parts. When the speed is low and the work is unstable, even the connecting rod, bearing bush and other parts will work under abnormal loads, causing accidents such as bearing bush alloy falling off
