METHOD AND DEVICE FOR INJECTING CATALYST COMPOUND FOR ELIMINATING EXHAUST GAS IN DIESEL ENGINE

摘要

PURPOSE: A device for injecting a catalyst compound for eliminating exhaust gas is provided is installed at the common fuel supply line to be operated with a pressure of a fuel pump and uses a fuel flowing through the fuel supply line as a solvent to dissolve the catalyst compound, so that the structure is simplified and the installing cost is reduced. CONSTITUTION: In a device for injecting a catalyst compound for eliminating exhaust gas, a plurality of fuel supply lines(9) are equipped to supply a fuel inside a fuel tank(7) to a combustion chamber(1) with a pressure of a fuel pump(3). An airtight container(5) containing the catalyst compound is installed at a part of one fuel supply line(9b) among the plurality of fuel supply lines to make the catalyst compound dissolved fuel to flow with a prescribed amount. The plurality of fuel supply lines are united to mix the catalyst compound dissolved fuel and a fuel directly supplied from the fuel tank with a prescribed ratio. And the mixed fuel is supplied to the combustion chamber via the fuel pump.
