How often should shock absorber top rubber be replaced?

There is no fixed replacement interval for automotive shock absorber top rubber. Generally, it should be replaced when it is broken. The connection between a shock absorber on a car and the car body is provided with a buffering rubber part, which is also called shock absorber top rubber. It can cushion vibration and improve driving comfort. Shock absorber is designed to suppress vibration of rebounding springs after shock absorption and impact from road surface. It leads to smoother drives effectively. When a car runs, although the shock-absorbing springs dampen the road impact, they move reciprocally. Shock absorber is intended to suppress such reciprocating motion. Generally, heavier vehicles use harder … Read more…

What it’s the working principle of EGR valve cooler?

The main part of an EGR system is a numerical control EGR valve. The valve is installed on the right exhaust manifold to enable independent and accurate control of the amount of exhaust recycled to the engine irrespective of the vacuum degree in the manifold. The EGR valve has three gauging hatches with increasing diameters. They help control the amount of exhaust flowing from the exhaust manifold back to the intake manifold and provide seven flow options. Each gauging hatch consists of a solenoid valve and a needle valve. After the solenoid valve is energized, the armature is pulled upward by the magnet, causing the gauging hatch to open. The … Read more…

What are possible reasons for a leaky crankshaft rear oil seal?

1. If the parallelism between the press fitting surface of the crankshaft rear oil seal and the mounting surface of the rear oil seal seat fails to meet the specification, the rear oil seal lip may deform under uneven load after the engine is used for some time. Consequently, the oil seal will fail and leak. 2. If the crankshaft rear oil seal is pressed fitted by using engine oil in place of more expensive non-petroleum base lubricant, the engine may loosen or fall off after being used for some time. 3. If the engine is used for too long, cracks may develop at the seal lip due to natural … Read more…
