The working principle of car tappet and intake valve: As the engine heats up, the components of the valve train are heated and expand, causing dimensional changes. Therefore, in the valve train using rigid tappets, there must be a certain gap between the valve stem and the tappet (or rocker arm). Before the camshaft comes into contact with the valve, the cam profile lifts the tappet to eliminate the gap. Then, the parts of the valve train move as a whole. When the air is closed, the camshaft base circle turns to the bottom of the valve lifter, the air valve mechanism reappears a gap. When the engine is working, the valve will expand due to the increase in temperature. If there is no gap between the valve and its transmission parts in the cold state or the gap is too small, the thermal expansion of the valve and its transmission parts will cause the valve to close in the hot state. Lax, causing air leakage during compression and work strokes, reducing power, and even difficult to start and burn the valve in severe cases.
