What is VVT-i?

[LeBraxton]

VVT-i stands for Variable-Valve-Timing-intelligent, which represents the intelligent adjustment of intake valve opening and closing timing to increase air charge. Below is a brief introduction to VVT-i: 1. General Overview: The VVT-i system is used to control the intake valve camshaft, adjusting the camshaft angle within a 50° range to optimize the valve timing according to the engine's operating conditions. This enhances the engine's power, fuel efficiency, and reduces exhaust emissions across all speed ranges. The VVT-i system consists of three main components: the VVT-i controller, the camshaft timing oil control valve, and sensors. 2. Features and Functions: (1) High feasibility. It can balance the requirements of both high-speed and low-speed conditions, improving the engine's power and fuel economy. (2) Reduced emissions. It helps lower the engine's exhaust emissions. (3) Improved performance. It enhances the engine's idle and low-speed performance and stability.
