AI Explanation
The correct answer is D) adjustable to meet lubrication requirements. Mechanical lubricators for diesel engine cylinders are usually small reciprocating pumps that are adjustable to provide the appropriate amount of lubrication to the engine cylinders based on the engine's operating conditions. This allows the lubricator to be adjusted to meet the changing lubrication needs of the engine, whether it is operating at low, medium, or high load. The other answer choices are incorrect because they do not accurately describe the typical operation and function of a mechanical lubricator for a diesel engine.
