Vehicular internal combustion engine fuel-borne catalyst and application thereof

Abstract

The invention discloses a vehicular internal combustion engine fuel-borne catalyst and application thereof. The vehicular internal combustion engine fuel-borne catalyst comprises, by mass percent, 65-80% of tourmaline, 3-8% of aluminum oxide, 15-30% of iron oxide and 1-3% of dicerium trioxide. The vehicular internal combustion engine fuel-borne catalyst has the advantages of safety, reliability, simplicity in application, no physicochemical damage to an engine, no influence on a vehicular structure, a circuit, an oil circuit and mechanical properties, capability of achieving remarkable energy-saving and emission-reducing effects, lower vehicular maintenance cost, higher power, low use cost and long service life and can be applied to various diesel vehicles, gasoline vehicles, LPG (liquefied petroleum gas) vehicles and the like.

Description

【Technical field】 [0001] The invention relates to a fuel catalyst for an automobile internal combustion engine and its application, belonging to the field of automobile tail gas purification. 【Background technique】 [0002] Automobile exhaust pollutes the atmosphere very seriously, and its treatment is a major issue facing human beings. The three-way catalytic converter is the most mature device widely used in the treatment of automobile exhaust, but because the three-way catalytic converter is a device belonging to the exhaust system, it only treats the exhaust gas and cannot be processed in the combustion chamber, and because of The quality level of fuel oil is generally low, which makes the catalyst of the three-way catalytic converter extremely susceptible to corrosion and damage by phosphorus, sulfur and other poisons, resulting in abnormal engine operation, increased fuel consumption, power decline and excessive exhaust gas. The three-way catalytic converter is general...

Problems solved by technology

The three-way catalytic converter is the most mature device widely used in the treatment of automobile exhaust, but because the three-way catalytic converter is a device belonging to the exhaust system, it only treats the exhaust gas and cannot be processed in the combustion chamber, and because of The quality level of fuel oil is generally low, which makes the catalyst of the three-way catalytic converter extremely susceptible to corrosion and damage by phosphorus, sulfur and other poisons, resulting in abnormal engine operation, increased fuel consumption, power decline and excessive exhaust gas. The three-way catalytic converter is generally used 80,000 to 100,000 kilometers will gradually fail, increasing the cost of the car owner and causing increased exhaust emissions

Up to now, the major car manufacturers have not found an ideal product or device that can effectively control vehicle exhaust emissions and low cost on the basis of improving combustion efficiency.
