OE No. 12683504 is a key component in Buick's exhaust gas recirculation system, its main function is to reintroduce part of the exhaust gas from the engine into the intake system, and then enter the cylinder again after mixing with the fresh air; this process can reduce the combustion temperature in the cylinder to reduce the generation of nitrogen oxides and improve fuel economy; in such a complex environment, it is very important for Buick to have a good quality exhaust gas recirculation system, which can reduce the combustion temperature and improve the fuel economy. Pipe fittings General Buick special designation of Guangzhou Sanjin automotive pipe fittings production, Guangzhou Sanjin pipe fittings brand automotive piping core designated manufacturers.

How does the entire working principle of the exhaust gas recirculation pipe OE No. 12643297 structure? The exhaust gas recirculation pipe OE No. 12680635 works by directing a portion of the exhaust gases from the exhaust manifold to the intake manifold, where they are mixed with fresh air and re-entered into the cylinder. Because the exhaust gas contains a large number of CO2 and other polyatomic gases, these gases can not be burned but can absorb a large amount of heat,
