70% to passThe air compressor shown in the illustration, when used aboard a vessel is typically operated as _______________. Illustration GS-0119
Aa diesel engine air start unit only
Ba constant pressure unit while operating under all load conditions
Can on-off cycle unit
Da constant capacity unit
AI Explanation
The correct answer is D) a constant capacity unit. The air compressor shown in the illustration GS-0119 is typically operated as a constant capacity unit when used aboard a vessel. This means that the compressor maintains a constant flow rate of air regardless of the load conditions. This ensures a reliable and consistent supply of compressed air for various onboard systems, such as starting engines or operating pneumatic tools. The other answer choices are incorrect because: A) the air compressor is not solely used for diesel engine air start, B) it does not operate at a constant pressure under all load conditions, and C) it does not cycle on and off based on demand.
