What is the vvt solenoid valve for automobiles?

VVT is the abbreviation of VariableValveTiming, which means variable timing valve system.

This is a technology used in automobile piston engine. VVT technology can adjust the overlapping time and timing of engine intake and exhaust system, reduce fuel consumption and improve efficiency.

VVT engine is one of the new technologies gradually applied to modern automobiles in recent years. By adopting variable valve timing technology, the engine can improve the intake charge and charge coefficient, and the torque and power of the engine can be further improved.

Working principle of VVT valve

Piston engines usually intake and exhaust air by lifting the throttle valve, which is directly or indirectly driven by the cam on the camshaft. If it is broken, there will be a fault code.

The variable valve timing system of OCV VCT Company consists of solenoid valve (OCV) and variable camshaft phase adjuster (VCT). By adjusting the engine cam phase, the intake air can be changed with the engine speed, so as to achieve the best combustion efficiency and improve fuel economy.

VVT crankshaft drives camshaft through timing belt, gear or chain. The profile and position of the cam on the camshaft are usually optimized for a specific engine speed, which usually reduces the torque at low speed and the power at high speed.
