The fuel injection pump is an important part of the diesel engine. The engine crank gear drives the camshaft to rotate to complete the fuel injection function.
A governor is generally installed on the fuel injection pump to ensure the low-speed operation of the diesel engine and the limitation of the maximum speed to ensure a certain relationship between the injection volume and the speed.

At present, the bridge covers used in automobiles mainly include punch-welded bridge housings, cast bridge covers, and internal expansion bridge covers that are expanded by slotting in the middle of billet or billet. With the development of the automobile industry, stamping and welding axle housings have been used in the production of axle housings in batches.

A fuel injector is a valve. The gas or diesel fuel can be delivered to the right place in the right amount at the right time, mixed with air and burned in the engine. The injector is the most critical system part assembly in the electronic fuel injection engine.

Automatic adjusting arm, generally refers to "brake gap adjustment arm" or "automatic gap adjustment arm", can automatically and timely adjust the gap increased by wear, so that the brake gap is always maintained within the design safety range.

The thrust rod rubber core is the most widely used rubber product in the whole vehicle. It is used for shock absorption, buffering, limiting, protection, sealing, etc.

The key to the structure of the glass lifter is the motor and the reducer. These two are assembled into one body. The motor adopts a reversible permanent magnet DC motor. There are magnetic field coils with different winding directions in the motor. The motor is controlled by a double switch button, with three working states of up, down, and off. When the switch is not operated, it will automatically stop at the "off" position.

The function of the power steering gear is to appropriately transform the steering torque and steering angle from the steering wheel (mainly deceleration and increase torque), and then output to the steering rod mechanism to turn the car. So the steering gear is essentially a deceleration transmission device. Generally, there are 1~2 speed reduction transmission pair.
