Causes garbage trucks to start difficult or fail to start Garbage trucks are basically running every day, especially for garbage truck drivers. They are relatively hard and get up early every day. However, sometimes garbage trucks do not start easily or the engine runs abnormally after starting. Mainly check this. Problems. First, it is difficult to start or can not start (a), start the speed is normal, there is smoke emission at the start, there are intermittent bursts. The essence of this failure is that diesel has entered the cylinder, but it is difficult to fire. The causes of this failure are: too late injection or serious inaccurate injection; severe wear of the injection pump plunger; poor sealing of the cylinder (2) The garbage truck starts at a normal speed, smokelessly discharged when starting, and there is no explosion sound. The essence of this failure phenomenon is that diesel does not spray the cylinder. The basic reason for this failure is that the injection pump does not pressurize the oil or the low pressure oil line does not supply oil. The basic reasons are as follows: 1. The reasons why the fuel injection pump does not press oil include: air in the oil passage, pull-rods of the fuel injection pump operating mechanism fall off, and adjustment rods stuck in stopping fuel supply or flameout. Loose fixing bolts that drive the connecting plate. 2. The reasons why oil is not supplied by the low pressure oil line are: There is no oil in the oil tank, there is air in the oil passage, the oil line is blocked and the oil pump does not work. At this time, it should be based on the principles of easy-to-follow, first-out, and then-inside-out rules. First, check whether the fuel injection pump flame-out button is returned, whether the lever of the operating mechanism and the fixing bolt of the driving connection plate are detached, and whether there is oil in the fuel tank. Then, loosen the gas release screw on the fuel injection pump to check whether the oil line is blocked or air. And press the start button to check if the pump is working properly. If the above checks are all good, you should remove the high-pressure fuel pipe on the fuel injection pump, then fall down the accelerator pedal, press the start button, check the fuel injection pump for pressure. If you do not press the oil, it means that the adjusting rod is stuck in the stop position. Guangdong Heidler Technology Co., Ltd , https://www.hyhemit.com
