Question

A timing belt, gears, or a chain drives the engine's camshaft at Blank the rotation speed of the crankshaft.

A) Half
B) Double
C) One-fourth
D) Twice

Answer 1

The camshaft in a four-stroke engine rotates at half the speed of the crankshaft, enabling synchronized valve timing for engine operation.

Step-by-step explanation:

In automotive engineering, the relationship between the camshaft and crankshaft rotation speeds is critical for proper engine timing and function. For a four-stroke engine, the correct answer to the question is that the camshaft rotates at half the speed of the crankshaft. This means that for every two revolutions of the crankshaft, the camshaft completes one revolution, ensuring that the engine's intake and exhaust valves open and close at the correct times during the combustion cycle.
