Análisis para el reacondicionamiento de catalizadores de 3 vías en los vehículos con motor a gasolina

Abstract

The study presented refers to two methods for the reconditioning of the three-way catalytic converter in gasoline vehicles carried out in the city of Quito, this procedure focuses on the use of two cleaning methods with a machine that uses a process of electrolysis with energy sources dissociating oxygen and hydrogen and an additive that takes care of the accumulation of soot and cleans the combustion chamber and injection reducing polluting gas emissions. Possible causes of the decrease in catalyst efficiency may include inadequate air/fuel mixture, faulty spark plugs and oxygen sensors, as well as incorrect engine timing. To carry out these tests we used two vehicles that have a higher mileage of 100,000, a vehicle Aveo GTA5 year 2009 and a Nissan Xtaril year 2008, following the regulations of regularization of gases and proposed methodology is obtained as a result favorable data in hydrocarbons with a reduction of 90% however in the O2 does not work because it has an increase with the reconditioning with the machine. With the additive there is an efficiency of 50%, because the engine does not have a good acceptance when applying the additive. In summary, when applying the two reconditioning methods there is no improvement in gas emissions.
