What does variable timing valve mean?

Variable valve timing is a technology applied to automobile piston engine. The system adjusts the phase of the engine cam through the equipped control and execution system, so that the opening and closing time of the valve changes with the change of the engine speed, thus improving the charging efficiency, increasing the engine power, reducing the fuel consumption and improving the efficiency. The relevant information is as follows:

1. Definition: VCTOCV variable valve timing system consists of solenoid valve OCV and variable camshaft phase adjuster VCT. By adjusting the cam phase of the engine, the intake air changes with the change of engine speed, so as to achieve the best combustion efficiency and improve fuel economy.

2. Working principle: Piston engines usually intake and exhaust air by lifting the throttle valve, which is directly or indirectly driven by the cam on the camshaft. In each intake and exhaust cycle, the cam drives the valve to open and lift for a certain time. Million car purchase subsidy
