AG Mechanics CDE Practice Exam

The camshaft gear is ________ as large as the crankshaft gear.

1. 1/2 times

2. 2 times

3. 4 times

4. equal in size

The correct answer is: 2 times

The camshaft gear is 2 times as large as the crankshaft gear because the camshaft gear typically has double the number of teeth compared to the crankshaft gear. This gearing ratio ensures proper timing and coordination between the camshaft and crankshaft in an engine's operation. Option A (1/2 times), C (4 times), and D (equal in size) are incorrect because they do not reflect the typical relationship between the sizes of the camshaft and crankshaft gears in an engine.
