Abstract (en)

[origin: WO2019110877A1] A device for reducing the quantity of nitrogen oxides emitted in the exhaust fumes of a diesel engine, said diesel engine comprising a combustion chamber (34) and an air compressor (29), said device comprising: - a water treatment system, for demineralising the water to be injected, - a water injection system, for injecting the demineralised water into said diesel engine, said water injection being carried out after said air compressor (29) and before said combustion chamber (34), said water injection into the combustion air enabling a lowering of the combustion temperature and thus of the emissions of nitrogen oxides, - safety means, such as probes and solenoids, for limiting and/or preventing the risks of malfunction of said diesel engine because of said device, and - a control system, comprising control means for determining the water injection parameters and/or for managing said safety means.
