Question

at what speed does the crankshaft rotate as compared to the camshaft?
select one:
○ a. same speed
○ b. twice as fast
○ c. half speed
○ d. one - third

Explanation:

In an internal combustion engine, the crankshaft rotates twice for every one rotation of the camshaft. This is because the four - stroke cycle (intake, compression, power, exhaust) requires two full rotations of the crankshaft to complete. The camshaft, which controls the opening and closing of the valves, only needs to rotate once for the four - stroke cycle.

Answer:

B. Twice as fast
