DEVICE FOR SUPPLYING WATER IN AN INTERNAL COMBUSTION ENGINE OF A SUPERCHARGED PISTON FOR INJECTING WATER BETWEEN THE TURBOCHARGER AND A CHARGE COOLER

摘要

PURPOSE: A water supply device of a turbocharger internal combustion engine is provided to mix water drops with supply air actively, and to evaporate water optimally by injecting water in the opposite direction to flow direction of air supplied by a compressor. CONSTITUTION: A water supply device of a turbocharger internal combustion engine for reducing Nox injects water between the turbocharger and a charge cooler(4). An injection nozzle(10) is installed in a supply air flow traverse section, or mounted in the outlet of a compressor. The supply air traverse section is expanded, and composed of an outlet of a compressor discharge helix(2) and a diffuser(3) connected to the compressor discharge helix. Water is injected in the opposite to flow direction of air supplied by the compressor, and the injection nozzle is installed in the end of a window type supply pipe(7). The supply pipe is mounted in a housing cover of a housing guiding air to the charge cooler.
