If a scavenging air space fire occurs on a slow speed diesel engine and the engine is stopped, which of the following should be done to prevent distortion due to heat?
AI Explanation
The correct answer is B) Engage and turn the engine with the jacking gear.
When a scavenging air space fire occurs on a slow speed diesel engine, the best action to prevent distortion due to heat is to engage and turn the engine with the jacking gear. This allows the engine to be slowly rotated, which helps to evenly distribute the heat and prevent localized hot spots that could lead to distortion of engine components. Letting the fire burn out naturally (A) or opening the engine to inspect the hot area (C) would not effectively distribute the heat, and using CO2 to extinguish the fire (D) could cause rapid cooling that could also lead to distortion.
