Product Description
Automobile camshaft adjuster usually consists of the following components:
1. Control unit: The control unit of camshaft adjuster is the core of the whole system, which is responsible for receiving signals from sensors and controlling the phase and timing of camshaft according to engine working conditions and driving requirements. The control unit usually consists of an electronic control module (ECM) or an electronic control unit (ECU).
2. Sensor: The sensor is used to monitor the working state and driving conditions of the engine to provide the data required by the control unit. Common sensors include crankshaft position sensor, camshaft position sensor and valve position sensor.
3. Oil system: The camshaft adjuster usually needs hydraulic pressure to adjust the phase and timing of the camshaft. The oil circuit system includes oil pump, oil pipe, nozzle and other components, which are used to transmit hydraulic pressure to the camshaft adjuster.
4. Camshaft adjuster: Camshaft adjuster is a device actually used to adjust camshaft phase and timing. It can change the position of the camshaft by hydraulic pressure or motor drive, so as to adjust the opening time of the valve and advance or delay the ignition timing.
The function of camshaft adjuster mainly includes the following aspects:
1. Improve the power and torque output: By adjusting the phase and timing of the camshaft, the camshaft adjuster can optimize the opening and closing time of the valve, thus improving the intake and exhaust efficiency of the cylinder. This can increase the power and torque output of the engine.
2. Improve the combustion efficiency: The camshaft adjuster can adjust the ignition timing to make it more suitable for the engine requirements under different working conditions. This can optimize the combustion process, improve combustion efficiency and reduce fuel consumption and emissions.
3. Improve low-speed and high-speed performance: The camshaft adjuster can adjust the phase and timing of the camshaft according to the change of driving conditions and engine load to provide better low-speed and high-speed performance. It can provide more torque output when driving at low speed; When driving at high speed, it can provide greater power output.
In a word, the function of the automobile camshaft adjuster is to optimize the opening and closing time of the valve by adjusting the phase and timing of the camshaft, so as to improve the engine performance, combustion efficiency and driving experience.
