Engineering · Diesel — Safety
After a diesel engine trips on suspected overheating, you should NOT immediately:
- AReduce or remove the load
- BOpen the crankcase doors to inspect✓ Correct
- CKeep auxiliary lube-oil and cooling pumps running
- DInvestigate the cause
Explanation
Opening the crankcase right after a hot shutdown can admit a rush of air to an oil-mist atmosphere and trigger a secondary explosion. Allow it to cool first while keeping lube/cooling circulating.
