GOODBYE SMOKE, HALLO-SWIRL

Nearly every operator of a diesel engine is familiar with smoking exhaust. Some engines experience black smoke at high loads; others emit white or bluish smoke at low loads; some endure both. The phenomenon is the result of incomplete combustion. It is described how the Deutz-MWM 604B diesel, which covers 900 to 2,630 hp output range at 1,800 rpm maximum, incorporates a simple solution that optimizes engine performance while virtually eliminating incomplete combustion at every stage from low load to high load operation. It accomplishes this through the design of the air channels and the use of a flap in one of them. The engine swirl becomes "high and low load optimized," hence the acronym "HALLO-SWIRL."
