🔍 Key Concepts

• Location and function of a camshaft in a V‑type diesel (what mechanical parts it works with in the head/block) • Speed relationship between crankshaft and camshaft in a four‑stroke vs two‑stroke engine • How the gear train or drive at the front of the engine changes speed between crankshaft and camshaft

💭 Think About

• From the illustration, which labeled shaft clearly operates the valve and fuel injection cams? Trace which one has cam lobes and followers going up toward the valves. • Is this engine operating on a four‑stroke or two‑stroke cycle based on the presence of intake and exhaust valves in each head? How does that determine the camshaft speed relative to the crankshaft? • Look at the gear sizes between the crankshaft and the suspected camshaft: do they indicate the driven shaft is running at the same speed or at half speed?

✅ Before You Answer

• Verify which label is attached to the shaft with cam lobes and followers leading to the valve gear and fuel pumps. • Confirm whether the engine cycle shown is four‑stroke (camshaft = 1/2 crankshaft speed) or two‑stroke (camshaft = crankshaft speed). • Double‑check that the chosen option correctly pairs both the physical shaft label and the correct speed ratio to the crankshaft.

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

"B" is the camshaft and its rpm will match that of the flywheel.

"T" is the camshaft and its speed equals crankshaft speed.

"Y" is the main camshaft drive and rotates at crankshaft speed.

"B" is the camshaft and it rotates at one-half of the crankshaft speed.
