A BMW 5281 DEC catalytic converter can help to reduce the harmful effects of your automobile’s exhaust. This exhaust naturally contains carbon monoxide, hydrocarbons, and nitrogen oxide. Each one of these elements alone could cause serious problems for your health and the environment. Located at the front of your exhaust line, a BMW 318TI 1999 catalytic converter vaguely resembles a muffler with its tubular design. As the exhaust flows through it, chemical reactions occur changing these harmful elements into less harmful ones. It turns carbon monoxide into carbon dioxide, nitrogen oxide into nitrogen and oxygen, and hydrocarbons into water. Failure of this automotive component is caused by a fuel mixture that is too rich. That too rich mixture can in turn create heat stress. This problem could be caused by an emission of too much unburned fuel, your computerized controls could be sending too much fuel into the combustion chamber, or your fuel injectors could have problems. The underlying cause of the problem needs to be discovered and fixed before changing out your BMW318TI DEC catalytic converter so that failure will not occur again in a short amount of time.
