Which of the diesel engine exhaust mufflers listed is usually equipped with a spark arrestor?
AI Explanation
The correct answer is C) A dry-type exhaust muffler.
Dry-type exhaust mufflers are typically equipped with a spark arrestor, which is a safety device that prevents sparks or hot particles from being expelled in the exhaust. This is an important feature for diesel engines used in marine applications, as it helps prevent the risk of fire or explosion.
The other options, such as wet-type, constant pressure, and constant velocity mufflers, do not typically have built-in spark arrestors. These types of mufflers are designed to reduce noise and backpressure, but do not necessarily incorporate the spark-prevention feature that is common in dry-type mufflers.
