Which of the following represents the diesel engine camshaft shown in the illustration and its relative rotating speed? Illustration MO-0122

Correct Answer: Option B — "B" is the camshaft and its rpm will match that of the flywheel.

In specific configurations illustrated in MO-0122, camshaft 'B' is gear-driven to rotate at crankshaft speed matching the flywheel RPM, tailoring valve and injection timing directly to the specific four-stroke or two-stroke cycle parameters of the propulsion unit.
