Product Description
Camshaft gears are used to control the opening and closing timing and amplitude of valves in engines, including intake camshaft gears and exhaust camshaft gears. They have some differences in function and design, as follows:
1. Functional differences:
-intake camshaft gear: the intake camshaft gear controls the opening and closing of the engine intake valve. The timing of opening and closing the intake valve is very important for the combustion process and power output of the engine. The design of intake camshaft gear and cam shape will affect the opening and closing speed, duration and lift of intake valve, thus affecting the airflow and combustion efficiency in the combustion chamber.
-Exhaust camshaft gear: The exhaust camshaft gear controls the opening and closing of the engine exhaust valve. The timing of opening and closing the exhaust valve is very important for the smooth flow of discharged combustion products and exhaust gas. The design of exhaust camshaft gear and cam shape will affect the opening and closing speed, duration and lift of exhaust valve, thus affecting the efficiency of exhaust system and the performance of engine.
2. Design differences:
-Cam shape: The cam shapes of the intake camshaft gear and the exhaust camshaft gear are usually different. The cam shape of the intake camshaft gear is usually designed to provide a larger intake valve lift and a longer opening time in order to increase the intake air volume and intake efficiency. The cam shape of the exhaust camshaft gear is usually designed to provide a smaller exhaust valve lift and a shorter opening time, so as to discharge exhaust gas and combustion products quickly.
-Camshaft phase: The phases of the intake camshaft gear and the exhaust camshaft gear are usually different. Camshaft phase refers to the angle difference between camshaft and crankshaft, which determines the opening and closing timing of the valve. The phase of intake camshaft gear and exhaust camshaft gear can be adjusted according to the needs of engine design to achieve the best intake and exhaust effects.
The difference of intake and exhaust functions of camshaft gears makes them different in design and performance. This difference exists to meet the intake and exhaust requirements of the engine under different working conditions, so as to improve the combustion efficiency, power output and emission performance. For the maintenance of camshaft gears, it is necessary to check and adjust them according to the characteristics and working requirements of intake and exhaust camshaft gears.
