Product Description
Automobile eccentric shaft refers to the shaft connecting the engine crankshaft and camshaft, which is usually composed of camshaft gear and crankshaft gear. Its main function is to adjust the valve timing of the engine to ensure that the valve opens and closes at the right time, so as to realize the intake, compression, deflagration and exhaust of the fuel mixture and ensure the normal operation of the engine.
Specifically, the eccentric shaft of automobile is driven by camshaft gear and crankshaft gear, which makes the relative position between camshaft and crankshaft shift, thus adjusting the opening and closing time of valve. This eccentric design can make the valve have different opening and closing times in different working stages of the engine to meet the working requirements of the engine under different speed and load conditions.
The working principle is that when the crankshaft rotates, it is transmitted to the camshaft gear through the crankshaft gear, so that the camshaft produces offset motion relative to the crankshaft. This eccentric movement changes the opening and closing time of the valve, makes the valve open and close at the right time, ensures the synchronization of the movement of the valve and the piston, and realizes the intake, compression, deflagration and exhaust processes of the fuel mixture.
Generally speaking, the automobile eccentric shaft plays an important role in adjusting the valve timing in the engine. By adjusting the opening and closing time of the valve, the normal operation of the engine can be ensured. Its working principle is that through the transmission between the camshaft and the crankshaft, the camshaft generates offset motion and adjusts the working time of the valve to realize the efficient and stable operation of the engine. Therefore, the design and working principle of the eccentric shaft have an important influence on the engine performance and fuel economy, and it needs regular inspection and maintenance to ensure the normal operation and performance of the engine.
