WATER MIXING UNIT OF DIESEL ENGINE USING WATER/OIL EMULSIFIED FUEL

摘要

PURPOSE: A water mixing apparatus is provided to prevent environmental contamination by reducing the emission of nitrogen oxide and fine particles of smoke pollution. CONSTITUTION: The fuel oil which becomes to have high pressure by an injection pump, is supplied to a mixing unit and a water supply unit at the same time. The oil supplied to the mixing unit passes through the hole of an injector cap by the pushed action of a ball. The high pressure oil supplied to the water supply unit pushes a needle, extruding the water from the bottom of the needle. Thus-extruded water is transported to the mixing unit. The high pressure water passes the injector cap, swirling intensively along a guide groove of a connection unit, and is mixed with the oil supplied from the mixing unit. Thus-mixed oil passes through the three spiral grooves formed at the lower portion of the mixing unit. The three spiral grooves are spaced apart from each other such that the rotation and mixing operation of the mixed fuel is repeatedly performed. Thus-obtained water-fuel mixture is injected into the combustion chamber via an injector.
