Product Description
Camshaft gear controls the opening and closing timing and amplitude of the exhaust valve in the engine. The exhaust camshaft gear has the following characteristics:
1. Provide proper exhaust valve lift: The cam shape and design of the exhaust camshaft gear are designed to provide proper exhaust valve lift. Exhaust valve lift refers to the distance from closing to fully opening of exhaust valve. Proper exhaust valve lift can ensure the effective discharge of combustion products and exhaust gas to maintain the normal operation and performance of the engine.
2. Control the opening and closing speed of the exhaust valve: The cam shape and design of the exhaust camshaft gear can also affect the opening and closing speed of the exhaust valve. By controlling the opening and closing speed of the exhaust valve, the flow characteristics of the exhaust system can be optimized, and the exhaust efficiency and engine performance can be improved. Faster opening speed can promote the rapid discharge of waste gas and reduce the residual gas; Faster closing speed can avoid exhaust gas backflow and improve exhaust efficiency.
3. Adjust the opening time and duration of the exhaust valve: The cam shape and design of the exhaust camshaft gear can also adjust the opening time and duration of the exhaust valve. The opening time of the exhaust valve refers to the time point from closing to opening, and the duration refers to the length of time that the exhaust valve remains fully open. By adjusting the opening time and duration of the exhaust valve, the exhaust emission and exhaust pressure can be controlled to meet the requirements of the engine under different working conditions and improve the exhaust efficiency and engine performance.
4. Adapt to the exhaust demand under different working conditions: The design and adjustment of exhaust camshaft gear can make the engine adaptable under different working conditions. For example, under high load conditions, the exhaust camshaft gear can provide a larger exhaust valve lift and a shorter opening time to increase the exhaust volume and reduce the exhaust pressure. Under low load condition, the exhaust camshaft gear can provide smaller exhaust valve lift and longer opening time to reduce exhaust resistance and improve fuel economy.
