Can the automatic slack adjuster be applied to the engine valve train?

Automatic slack adjusters are not only used in braking systems, but also have corresponding application forms in engine valve mechanisms, often referred to as hydraulic tappets (hydraulic slack adjusters). The following is an analysis of its application in engine valve mechanisms:

1. Automatic compensation for changes in valve clearance:
During the operation of the engine, components such as valves, rocker arms, and camshafts may experience changes in clearance due to thermal expansion, contraction, or wear. The hydraulic clearance adjuster can automatically compensate for clearance changes in real time and maintain stable operation of the valve mechanism.

2. Improve valve opening and closing accuracy:
The automatic adjustment device can continuously maintain the optimal contact state between the valve and the cam, which helps to accurately control the valve opening and closing time, improve engine efficiency and performance.

3. Reduce mechanical noise:
If the clearance of the traditional valve mechanism is too large, it will produce obvious knocking sound. The use of hydraulic automatic clearance adjuster can effectively eliminate clearance noise and make the engine run more quietly and smoothly.

4. Reduce maintenance workload:
Traditional mechanical valve mechanisms require regular manual inspection and adjustment of clearances, while automatic adjustment devices do not require frequent maintenance, reducing maintenance frequency and costs.

5. Extend the lifespan of engine components:
Maintaining optimal clearance can reduce excessive friction and wear between components, helping to extend the service life of engine related parts.
