Clogged catalytic converter is evolving, clogged generation is reversible, such as oxidation and gasification blockage can be reduced by a chemical process, or by physical processes such as desorption and volatile components, the gaseous components and reduce evaporation. Clogged catalytic converters can be divided into three stages: the first stage is a slight blockage stage of this phase chemical complex adsorption on the catalyst surface, showing only reduce exhaust gas purification, emissions exceeded. 2, the second phase of moderate blockage phase chemical complex on the catalyst surface has been accumulated to a certain extent, this stage exhaust back pressure, increased fuel consumption, power down. 3, the third phase of severe congestion phase due to the severe congestion, catalytic converters working temperature, the catalytic converter in the front end of a high-temperature sintering blockage. High temperature sintering blockage is divided into two: one for metal sintering blocked. One for carbon sintering coke blocked. Whether it is by the use of leaded fuel, manganese anti-bao agent decided at this stage a serious decline in the performance of power, often stalled, severe red-hot exhaust pipe. Even cause spontaneous combustion vehicles. Wuhan Connaught Trade Co., Ltd. is China National Materials Germany Connaught lubricants and Johnson & Johnson architectural glass membrane Hubei only designated agents. China National Materials Company will promise the lubricating oil to China, access to Mercedes-Benz, Volkswagen, BMW, Porsche factory certification, from the German "blood" technology from the track.
