The importance of the camshaft in the entire engine design
The camshaft is an important part in the vehicle engine. Its function is to control the opening and closing of the intake valve and the exhaust valve. The regular movement of the valve is directly related to the output and operating characteristics of the engine power, and it is also the stable operation of the engine. Whether it is a key component or not, the camshaft occupies a very important position in the design of the entire engine.

In terms of shape, the main body of the engine camshaft is a cylindrical rod-shaped design. There are multiple protrusions and camshafts with different orientations to push the cylinder. The overall length is similar to the standard of the cylinder group. The raised camshaft side on the engine camshaft looks like a raw egg nearby. Its function is to operate the intake port and exhaust pipe of the hydraulic cylinder when it is pushed and rolled by the engine crankshaft. Therefore, the main parameters of the camshaft will be harmed together. Output power to the module, torque output, and running smoothness.

According to the different design of the crank connecting rod mechanism, the engine camshaft can be divided into three types: low-mounted, middle-mounted and overhead. Among them, the bottom-mounted engine camshaft is located in the crankcase ventilation, and the middle-mounted engine camshaft is located at the upper end of the human body. , while the overhead engine camshaft is located in the cylinder room above the cylinder head.

The module that chooses the bottom-mounted engine camshaft is more extensive, and its intake and exhaust pipes are located at the top of the module, while the engine camshaft is located on the ventilated side of the crankcase. Wait for the crank connecting rod mechanism to deploy the cylinder.

Design schemes such as under-engine camshafts are usually selected for modules with high horsepower, low speed ratio, and high torque output. They are widely used in high-horsepower modules common in some American muscle cars. They are characterized by simple structure and high stability. , low cost, module focus, etc.
The following camshaft wholesale, camshaft manufacturers and camshaft brand companies talk about how to install the car camshaft?

Car engine camshafts generally have several support journals to match the camshaft bearing bushes in the cylinder head.
The size of the camshaft journal of the automobile decreases in turn from the end of the transmission gear, which is convenient for the installation and removal of the camshaft.
After the automobile camshaft is installed in the cylinder head, the camshaft should be locked with a locking piece before the transmission gear is installed to prevent axial movement.
The drive gear of the camshaft can then be installed. The transmission gear is generally positioned and fixed with a crescent key.
Then you need to remind that when installing the timing transmission (timing belt or timing chain), pay attention to the check and correction of the timing.
