1.Driving the Camshaft: By meshing with the timing chain or timing belt, it transmits the rotational motion of the crankshaft to the camshaft, driving the camshaft to rotate. It is a key component for the normal operation of the engine's valve train.
2.Controlling Valve Timing: It ensures that the camshaft accurately controls the opening and closing timings of the intake and exhaust valves in accordance with the engine's working cycle and firing order. This allows air and fuel to enter the combustion chamber at the right time and exhaust gases to be discharged promptly, ensuring the engine "breathes normally" and maintains stable operation.
3.Guaranteeing Valve Lift and Duration: In conjunction with the shape and size of the cams on the camshaft, it determines the valve lift (i.e., the extent to which the valve opens), which in turn affects the amount of air-fuel mixture entering the engine. At the same time, it controls the duration of valve opening and closing, which has a significant impact on core performance indicators of the engine, such as power output and fuel economy.
4.Enabling Valve Overlap Control: In the design of some engines, it participates in controlling the "valve overlap" (a state where the intake valve opens before the exhaust valve is fully closed) at specific moments. This function facilitates "scavenging"—using the inertia of exhaust gas flow to help remove residual exhaust gases from the combustion chamber while drawing in more fresh air. This improves engine performance, particularly optimizing torque performance in the low-speed range.
1.High-Quality and Durable Material: Typically made of high-quality carbon steel, forged alloy steel, alloy cast iron, or other premium materials. The camshaft journals and cam working surfaces undergo heat treatment followed by polishing, resulting in high hardness and strong wear resistance. This enables the sprocket to withstand the cyclic impact loads generated when the camshaft operates at high speeds and adapt to the harsh working environment inside the engine.
2.Precise Vehicle Compatibility: Designed for specific Renault models (such as the Clio II), it features the Original Equipment (OE) number 7700739336. It can perfectly match the timing system of the vehicle's engine, ensuring normal operation after installation and allowing the engine to deliver optimal performance.
3.Exquisite Manufacturing Process: The components are manufactured using precision machining techniques and comply with original factory technical specifications. Some products also undergo anti-rust treatment to effectively ensure product quality and service life. For instance, certain sprockets may hold international quality certifications such as ISO 9001/TS 16949.
High Transmission Efficiency: It exhibits excellent compatibility with timing chains or timing belts, enabling efficient power transmission, reducing energy loss, helping the engine reach higher speeds, and ensuring smoother operation.
