🔍 Key Concepts

• 46 CFR requirements for internal combustion engine construction on inspected vessels • Safety measures related to crankcase explosions and hot crankcases • Difference between what is recommended versus explicitly required by regulation

💭 Think About

• Look for the option that clearly matches a specific safety requirement you’ve seen in the engineering/inspection regulations for diesel or internal combustion engines. • Ask yourself which item is directly connected to preventing personal injury or fire/explosion after engine shutdown. • Which choices sound like they might be good design practices, but are not actually mandated in the regulations for all engines?

✅ Before You Answer

• Verify in 46 CFR which engine construction details are explicitly required, not just suggested. • Check if the regulations mention anything specific about crankcase doors/covers and hot surfaces after shutdown. • Confirm whether there is a blanket requirement for exhaust gas pressure monitoring on all engines, or if that is only for certain systems or not required at all.
