Question 50Motor Plants - 1st Asst/Chief

The correct answer is D) supply the force required to shift the engine camshafts axially to reverse engine rotation. This is correct because the cylinders labeled "B" and "C" in the illustration are typically used to provide the hydraulic force necessary to shift the engine camshafts axially, which allows the engine to be operated in reverse. This is a common feature in marine engines to enable maneuvering and docking of vessels. The other options are incorrect because they do not accurately describe the function of the cylinders "B" and "C" in the illustration. Option A refers to the engine governor, which is a separate system. Option B refers to lubricating a component "F", which is not mentioned in the question. Option C describes a greasing function, which is also unrelated to the cylinders in the illustration.
