When the camshaft is located within the engine block, what components may be included in the valve train?

When the camshaft is situated within the engine block, it typically works in conjunction with various other components in the valve train to facilitate the opening and closing of the engine's valves. These components include valve lifters, push rods, and rocker levers.

Valve lifters, also known as tappets, are crucial as they transmit the camshaft's movement to the push rods. They ensure that the motion generated by the camshaft is effectively transferred to other components in the valve train.

Push rods serve as connecting links between the lifters and the rocker arms. When the lifters move, they push the rods upwards, which in turn activate the rocker levers. This action is essential for achieving the desired valve lift, allowing for optimal engine performance.

Rocker levers, or rocker arms, convert the linear motion from the push rods into rotational motion, enabling the valves to open or close properly. Their design ensures that the timing and motion of the valves are synchronized with the engine's operation.

In sum, all these components—valve lifters, push rods, and rocker levers—play integral roles in the valve train, especially when the camshaft is located within the engine block, making the inclusion of all these components the correct and comprehensive
