Question 6Motor Plants - Assistant Engineer

The correct answer is B) 950 RPM. In a two-stroke cycle diesel engine, the camshaft rotates at the same speed as the crankshaft, which in this case is 950 RPM. This is because in a two-stroke engine, the crankshaft and camshaft complete one full rotation for every two strokes of the piston, unlike a four-stroke engine where the camshaft rotates at half the speed of the crankshaft. The other options are incorrect because: A) 475 RPM is half the speed of the crankshaft, which would be the case for a four-stroke engine. C) 1900 RPM is double the speed of the crankshaft, which is not possible for a two-stroke engine. D) 2400 RPM is an unrealistic speed for a typical diesel engine running at 950 RPM.
