12643698 Intake & Exhaust Camshaft Adjuster Sprocket Gear Fit for Buick Encore Chevy Cruze Malibu Spark Trax L4 1.4L 2016-2022, Variable Valve Timing (VVT) Sprocket Gear Replace 916638

Key Features

• Dynamic Adjustment of Valve Timing: Camshaft adjuster sprocket is the core component of the variable valve timing (VVT) system for automobile engines. It changes the relative angle between the camshaft and the crankshaft through hydraulic or electromagnetic control, so that the opening and closing time of the intake and exhaust valves change with the engine speed or working conditions to ensure the normal operation of the engine
• Optimize Fuel Efficiency: Improve low-speed torque or high-speed power output by dynamically adjusting valve timing. Delaying the closing of the intake valve at high speed increases the intake volume and improves explosive power. Improve engine power and fuel economy through precise phase control, effectively improving the driving experience
• Excellent Sealing Performance: Improved check valve design ensures the sealing of the hydraulic oil circuit to prevent oil pressure leakage after flameout and cause VVT failure. The special tooth shape design can reduce the noise generated when the vehicle is running, providing you with a comfortable driving experience
• Reliable and Durable: Made of high strength alloy, it is wear resistant and high pressure resistant. It can maintain good performance after long-term use, reduce the risk of jamming or breakage, reduce the trouble of frequent replacement, and effectively extend the service life
