B18664 Camshaft is an important part for an automotive engine. It serves the purpose of controlling opening and closing of air intake valve and exhaust valve. Regular movement of the valves has a direct bearing on engine power output and performance. The camshaft also plays a critical role in stable engine operation. It is therefore regarded as a key link in the engine design.
The body of the camshaft is a cylindrical rod with nearly the same length as the cylinder set. It is equipped with a few cams for driving the valves. As the camshaft is supported in the bearing hole with camshaft journals, the rigidity of the camshaft is heavily dependent on the number of the journals. In the case of insufficient camshaft rigidity, bending or deformation may occur during operation, thus impeding timed air distribution.
The side profile of the cam resembles an egg. This design is intended to ensure full air admission and discharge in the cylinders. Besides, in order to maintain durability and smooth operation of the engine, frequent and/or excessive impact on the air valves due to acceleration or deceleration during opening/closing cycles should be avoided, otherwise severe wear of the valves, louder noise, or other serious consequences may ensue. In sum, the cam may directly affect engine power, torque output, and smooth operation.
