Products Description
The working principle of the VVT hub is to dynamically adjust the opening time and valve lift of the intake and exhaust valves according to the operation of the engine to improve the efficiency and power of the engine. At low engine speeds, the system can delay the valve closing time to increase the intake air in the cylinder, thereby improving the engine's torque output. At high speed, the system can advance the valve closing time to make full use of intake inertia and increase the power output of the engine. This technology can significantly improve the aeration efficiency of the engine, optimize the intake volume, and thus improve the combustion efficiency. At the same time, it can also improve the fuel economy of the engine and reduce exhaust emissions. But the downside of VVT technology is that it may not have enough torque at medium speeds.
