The term “rocker” can refer to several different things depending on the context, but in a mechanical or engineering context, a rocker is typically a component that pivots or rocks back and forth to transfer motion or force. One common example is the rocker arm in an internal combustion engine. Basic Function In the context…

The rocker arm is a critical component in an internal combustion engine’s valve train. It is a lever that transfers the camshaft’s rotational motion into linear motion to open and close the engine’s intake and exhaust valves. This process is essential for the engine’s air-fuel mixture intake and exhaust gas expulsion, directly impacting engine performance…

The rocker cover, also known as the valve cover, is a critical component in an internal combustion engine. It is typically made of metal or plastic and is located on top of the engine’s cylinder head. The primary function of the rocker cover is to protect the engine’s rocker arms and valves, which are part…

Rubber springs are elastic components made from rubber materials, designed to absorb and dampen energy. They are commonly used in various applications, including automotive suspensions, machinery mounts, and vibration isolation systems. The primary function of a rubber spring is to provide cushioning and reduce the transmission of vibrations and shocks. Basic Function The basic function…

The Suspension Control Module (SCM) is an integral component in modern vehicles, responsible for managing and controlling the vehicle’s suspension system. It plays a crucial role in ensuring a smooth and stable ride by adjusting the suspension settings based on various driving conditions and inputs. Basic Function The primary function of the SCM is to…

The rear coil spring is a critical component of a vehicle’s suspension system. It is designed to absorb and dampen the impact of road irregularities, providing a smoother ride and maintaining vehicle stability. Coil springs are typically made of durable steel and are coiled in a helical shape, allowing them to compress and expand as…

A seat belt, also known as a safety belt, is a vehicle safety device designed to secure the occupant of a vehicle against harmful movement that may result from a collision or a sudden stop. It is a crucial component of a vehicle’s safety system, aimed at reducing the risk of injury or death in…

The rear main seal is a critical component in an internal combustion engine, located at the rear of the engine block. It seals the end of the crankshaft and prevents oil from leaking out of the back of the engine. This seal is essential for maintaining the engine’s oil pressure and ensuring that the engine…

A seat belt pre-tensioner is a safety device used in vehicles to enhance the effectiveness of seat belts during a collision. It is designed to tighten the seat belt almost instantaneously in the event of a crash, thereby reducing the slack in the belt and securing the occupant more firmly in their seat. Basic Function…
