B&W Unif low Scavenging System offers consistent running over a wide speed range. Uniflow Scavenging is simple: Only inlet ports in the cylinder liner and only one exhaust valve in the cover. It is efficient: Incoming air and displaced gases describe a straightforward flow pattern of low resistance, as in a tube. Advantages include low, symmetrical thermal loads on cylinder walls, cylinder cover and piston, plus low fuel and lube oil consumption. B&W Uniflow Scavenging is consi- stently effective - even when the engine runs at part-load where ample air excess provides for clean smokefree combustion and low temperatures. This is one important reason why B&W GF-engines run reliably and with low specific fuel consumption over a wide speed range - from Full Ahead to Dead Slow. B&W GF-engines mean low specific fuel consumption at all loads.
