One may see the invention of the internal combustion engine in two ways. On the positive side, the invention of the internal combustion engine gave rise to the invention of other machines dependent on it, and that includes the automobile. In fact, every vehicle today, including your GMC vehicle, runs on internal combustion engine. On the negative aspect, on the other hand, the invention of the internal combustion engine gave birth to a source of air pollution, a problem that is yet to be totally solved today. Good thing is that there is another technology that can counter this, at least in vehicles, and that is the catalytic converter.

Catalytic converters are emission control products that clean out the exhaust from your vehicle's gasoline engine to keep it free from harmful substances. Note that catalytic converters are used only on gasoline engines, as diesel engines have a different design, and thus a different exhaust mechanism. The common substances filtered out by the catalytic converter are the hydrocarbons, carbon monoxides and other harmful substances that comprise parts of the byproducts of gasoline combustion on your vehicle's engine.

Judging by its function, the catalytic converter seems to be just a simple device that filters out harmful substances from your vehicle engine's exhaust. But the process that goes inside the catalytic converter is not simply a filtering process but something more complex. Modern catalytic converters often consist of two catalysts: a reduction catalyst and an oxidation catalyst. Each of these catalysts is made of special metals that can induce chemical reactions with the various exhaust elements that the vehicle's engine produce. The reduction catalyst, in particular, destroys the nitrogen oxides through a special chemical process. The oxidation catalyst, on the other hand, rips out the carbon monoxide and the other hydrocarbons from the engine's exhausts.

The GMC vehicle line-up consists mostly of trucks, vans, SUVs and other large vehicles. Large vehicles like GMC vehicles require more power and are thus equipped with larger engines. In the same manner, GMC vehicles produce more harmful emissions, therefore requiring catalytic converters that work better than the regular catalytic converters. For this reason, General Motors have equipped their GMC vehicles with high performance GMC catalytic converters, designed to work better than the ordinary catalytic converter. GMC catalytic converters are also designed to be tougher to outlast the damages that may be incurred during the vehicles performance.

If in case your GMC catalytic converter gets damaged, it is important that you replace it with a new one as soon as you notice it. Federal rules disallow a road vehicle to be driven without catalytic converters. Here at Parts Train, you can find a lot of GMC replacement catalytic converter that would fit perfectly and easily on whatever GMC vehicle that you have. Our catalytic converters are tested for superior strength and quality so that it can outlast all the damages that may be brought by your GMC's regular routine work.
