INA Valve Tappet 1560500225

A valve tappet is a crucial component in an internal combustion engine that plays an essential role in the valve actuation system. Located between the pushrods and the valves themselves, the tappet, also referred to as a lifter or follower, is responsible for translating the rotational motion of the camshaft into the linear motion needed to open and close the engine's intake and exhaust valves. This action is vital for the engine's air and fuel intake and exhaust gas expulsion, directly influencing the engine's performance, efficiency, and responsiveness.

There are two primary types of valve tappets: solid and hydraulic. Solid tappets require manual adjustment to maintain the correct clearance, ensuring consistent valve operation. In contrast, hydraulic tappets automatically adjust to maintain zero clearance, allowing for quieter operation and reducing the need for frequent maintenance. Regardless of the type, a well-functioning tappet ensures smooth engine operation, optimal performance, and a longer lifespan for the engine components by mitigating excessive wear. Therefore, proper inspection and maintenance of the valve tappet are critical to the overall health of a vehicle's engine.
