How to adjust the idle speed of Haval h5 diesel?

But the accelerator pedal lever can't completely return (which is rare). If this is the case, check the accelerator pedal lever so that all the pull rods are completely relaxed. There are high-speed limit screws and low-speed limit screws on the fuel injection pump housing, which are used to limit the rotation range of the speed control handle (the screws pressed on the speed control handle in the state of throttle relaxation are low-speed limit screws).

These two limit screws are used to limit the maximum and minimum speed of the engine. The fuel injection pump is calibrated and adjusted on the oil pump test bench. The calibrated and adjusted fuel injection pump is sealed on the high and low speed limit screws with lead, and it is not allowed to be adjusted at will.

Idle speed grade:

Normal idle speed

When the vehicle is parked and the engine is started, the lowest rotation speed of the engine running stably is called parking idle speed (the process that the engine changes from the idle state of cold car to the idle state that the engine reaches the normal working temperature is called warm car or hot car).

Driving idle speed

When the car is in gear, the minimum opening of the throttle valve remains unchanged, and there is no need to step on the accelerator pedal or loosen it when driving. At this time, the engine speed is consistent with the parking idle speed, which is called driving idle speed.
