Working principle and structure of eccentric shaft

The working principle of an eccentric shaft is to detect its position through sensors, and then adjust the position of the eccentric shaft by an electronic valve adjustment servo motor until it reaches the standard position.

Eccentric axis sensors typically consist of two independent angle sensors with opposite characteristic lines, using a redundant design structure to ensure measurement accuracy and reliability.

The role of eccentric shaft in automotive engines

Eccentric shafts play a crucial role in automotive engines, optimizing engine performance by adjusting the movement of the camshaft.

Specifically, the eccentric shaft can dynamically adjust the intake valve lift according to the operating state of the engine, thereby improving the efficiency and performance of the engine.

Maintenance and fault impact of eccentric shaft

The maintenance of eccentric shafts includes regular checks on their working status and the operation of sensors. If the eccentric shaft motor malfunctions, it will affect the status of the electronic valves and lead to a decrease in engine performance.

Therefore, regular maintenance and inspection of the working condition of the eccentric shaft are crucial to ensure the normal operation of the engine.

We also provide eccentric shaft of BMW, Mercedes Benz, Volkswagen, Range Rover, Maserati, Audi, Volvo and other models of cars.

What can we provide for auto parts?

Gestar not only provides customers with various types and brands of used cars, but also relies on China's strong supply chain advantages to provide customers with various new and second-hand auto parts, from engine system, suspension system, braking system, electrical system, transmission system, fuel system, clutch systems to cooling system.

The core function of an automobile eccentric shaft is to optimize power transmission efficiency and enhance driving comfort through three major functions: motion form conversion, axle spacing adjustment, and engine balance. Specifically manifested as:

Movement form conversion

Transform rotary motion into reciprocating linear motion, such as driving the crankshaft in an engine or achieving mechanical energy transmission in a lubrication pump system.

This characteristic makes the eccentric shaft the core component of power conversion. Dynamically adjust the axis spacing

In planar linkage mechanisms and V-belt drives, adjusting the shaft spacing improves transmission efficiency and ensures that the power system maintains optimal coordination under different operating conditions.

For example, the camshaft phase can be optimized to control the intake valve lift, thereby improving engine combustion efficiency.

Balance engine operation

By offsetting the vibration energy through its own eccentric structure, it significantly reduces the noise and vibration during engine operation.

This balancing function is particularly important for the NVH (noise, vibration, and acoustic roughness) performance of hybrid vehicles. ‌

Details worth noting: In modern cars (such as those equipped with variable valve timing technology), eccentric shafts often work in conjunction with sensors to automatically adjust mechanical parameters based on real-time operating conditions, achieving more intelligent power control.

This design not only improves fuel economy, but also extends the service life of engine components
