The method of adjusting the throttle of the coupling engine

XINLANCouplingAnalyze the diesel engine installed on the crane. After long-term use, sometimes the speed increase will be slow when the accelerator is operated on the vehicle, and the maximum speed and maximum power cannot be reached.At this time, check and adjust the entire transmission chain of the pedal accelerator.This work requires two people, one is in the car to operate the accelerator pedal, and the other is to observe the movement of the speed control lever at the fuel injection pump.With cranes that have been used for many years, the operators in the cab of the vehicle have stepped on the accelerator pedal to the extreme position, but in fact the governor lever of the diesel fuel injection pump sometimes cannot reach the extreme position.Since the position of the speed control lever in the whole machine is not easily observed by the operator, its idle stroke is often ignored, so you should observe it for a while and try it several times.The reason for this situation is that the dimensional chain of the transmission system of the diesel engine throttle is changed, and the idle stroke in the middle is too large; the other is that the fasteners on some transmission devices, such as the set screws, are loose.At this time, check step by step according to the throttle transmission size chain. When the accelerator pedal is fully stepped on the vehicle, the speed control lever must also reach the limit.The idle stroke on the throttle drive chain should be retained as required, and should be tightened and adjusted according to the specific conditions of each device
