Exhaust gas purifying device

Abstract

The present invention provides a exhaust gaspurifying equipment. In a path of a fuel pipe 18 from a fuel tank 16 to an internal combustion engine 14, a tube body 24 packed with a catalyst material 10 made of a mixture of nylon and ceramics that generate minus ions is connected to impart negative electric charges to liquid fuel 12 such as petroleum that is supplied. Thereby, in a path of a fuel pipe from a fuel tank to an internal combustion engine, a catalyst that applies pre-combustion treatment to liquid fuel is interposed and thereby harmful matters in exhaust gas from the internal combustion engine is reduced.

Description

technical field [0001] The invention relates to an exhaust gas purification device, which is used in the field of exhaust gas purification of internal combustion engines of automobiles, ships, aircrafts, etc., especially on the fuel pipeline path from the fuel tank to the internal combustion engine, catalytic substances are arranged to reduce the exhaust gas discharged from the internal combustion engine harmful substances in. Background technique [0002] A 3D catalyst is usually installed in the exhaust pipe of an internal combustion engine in a car to after-process the harmful substances discharged from the internal combustion engine. In addition, the intermediate treatment is performed in a lean mixture engine that enhances the combustion effect of an internal combustion engine, and a direct injection diesel engine, a direct injection gasoline engine, and the like. However, there is a limit to sufficiently reducing harmful substances only through such post-treatment and...

Problems solved by technology

[0006] However, like the catalytic substance described in Patent Document 1, when any of nylon, silk, and tridymite is used as a monomer, the effect of reducing harmful substances does appear, but the effect cannot be sufficiently satisfactory.

Also, when silk or tridymite is used, there are disadvantages such as poor formability and easy variation in performance for each product.

[0007] In addition, like the catalytic substance described in Patent Document 2, when a plurality of materials are mixed in a predetermined weight ratio, the production process becomes complicated and the production cost increases.
