In an overhead cam engine, push rods are not needed to operate the:

a. Rockers and valves
b. Camshaft and valves
c. Camshaft and rockers
d. All of the above

Answer :

In an overhead cam engine, push rods are not required since the camshaft is located above the valves, allowing direct actuation of the valves. The correct answer is (b) Camshaft and valves, highlighting the design's efficiency in valve control.

The overhead cam design allows for more precise control of valve timing and has the potential to increase engine efficiency and performance compared to engines with a camshaft located in the engine block (also known as a pushrod or OHV engine).

In an overhead cam engine, push rods are not needed to operate the camshaft and the valves directly. This is because the camshaft is located in the cylinder head, above the valves, eliminating the need for push rods. Therefore, the correct answer is (b) Camshaft and valves.
