A crankcase explosion requires three elements: fuel (oil mist generated by a hot spot), air (present in the crankcase), and an ignition source (a friction-heated component like a main bearing, guide shoe, or piston rod stuffing box). Oil Mist Detector (OMD) Operations and Responses

Modern slow-speed engines (such as MAN B&W ME-C and WinGD RT-flex series) utilize electronically controlled, hydraulically activated exhaust valves instead of traditional mechanical camshafts. The Exhaust Valve Actuator (EVA) System

On a slow-speed crosshead engine, cylinder lubrication is a total-loss system separate from the crankcase oil. Base Number (BN) Selection

Keep auxiliary blowers running to maintain a safe airflow, provided the fire is not feeding off it. A crankcase explosion requires three elements: fuel (oil

You must be able to diagnose faults based on cylinder pressure diagrams: Low Pmaxcap P sub m a x end-sub (Maximum Pressure) & Low Pcompcap P sub c o m p end-sub

A hot spot (such as a wiping bearing) heats oil mist above its flash point. On a slow-speed crosshead engine, cylinder lubrication is

Indicates burning of lubricating oil. Likely causes: worn cylinder liners or broken piston rings.

Stop the fuel injection to the affected cylinder by lifting the fuel pump roller or cutting the electronic signal. Increase the cylinder lubrication to the affected unit to prevent seizure, unless the fire is fueled heavily by cylinder oil accumulation, in which case follow the manufacturer's specific guide.

Loud barking noises, fluctuations in scavenge air pressure, and high exhaust temperatures.
