Förfarande för att driva en kolvförbränningsmotor för minskning av NOx

摘要

Operating a piston engine, for reducing NOx emissions, involves running the engine in the whole load region with a fuel-water emulsion having a water amount of 15-20 wt.%, and running the engine above a load region of minimum 75% and below a load region of maximum 30% with an early ignition time point and in the middle load region with a later ignition time point.
