A catalytic converter is an exhaust emission control device that converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction. Catalytic converters are usually used with internal combustion engines fueled by gasoline or diesel, including lean-burn engines, and sometimes on kerosene heaters and stoves.
The first widespread introduction of catalytic converters was in the United States automobile market. To comply with the U.S. Environmental Protection Agency's stricter regulation of exhaust emissions, most gasoline-powered vehicles starting with the 1975 model year are equipped with catalytic converters. These "two-way" converters combine oxygen with carbon monoxide (CO) and unburned hydrocarbons (HC) to produce carbon dioxide (CO2) and water (H2O). Although two-way converters on gasoline engines were rendered obsolete in 1981 by "three-way" converters that also reduce oxides of nitrogen (NOx);they are still used on lean-burn engines to oxidize particulate matter and hydrocarbon emissions (including Diesel engines, which typically use lean combustion), as three-way-converters require fuel-rich or stoichiometric combustion to successfully reduce NOx.
Although catalytic converters are most commonly applied to exhaust systems in automobiles, they are also used on electrical generators, forklifts, mining equipment, trucks, buses, locomotives, motorcycles, and on ships. They are even used on some wood stoves to control emissions.This is usually in response to government regulation, either through environmental regulation or through health and safety regulations.
Description :
The basic job of a catalytic converter is to eliminate unburned fuel and potentially dangerous compounds from the exhaust beFore they can reach the environment.
If these toxic gases are not removed, then it can have dangerous effects on the environment. This device is specially designed to reduce the emissions of the vehicle and greenhouse gases.
However, if the converter is not working properly, and some issue arises, then the effect is very clear that even the driver sitting inside can easily notice it.
All in all, the high quality catalytic converter with high quality materials and precision tools. What's more, the product is covered with 5-year limited warranty.
NOTE: BeFore placing the order, please check year and model according your vehicle. So you will get a catalytic converter perfect fitting For your car. And professional installation is suggested.

Installation:
While we have taken every design precaution to ensure that this product will function correctly on the vehicles listed, it must be made clear that the original converter did not fail due to age or mileage. The factory converter is designed to last the lifetime of the vehicle. It has no moving parts and does not errode or otherwise wear out. The factory converter likely failed due to a fuel management problem or from chemical contamination due to impurities found in some fuels. The converter can only handle certain amounts of unburnt fuel. If the vehicle is running too rich, or if the combustion is not consuming most of the fuel beFore it enters the exhaust, the converter can be overheated or otherwise damaged. It is For this reason that the vehicle should be properly tuned on a regular basis. O2 sensors should be replaced every 80,000 miles, spark plugs every 60,000 - 100,000 miles, and the injectors and combustion chambers should be cleaned with a product designed For this purpose every 10,000 miles or every year. Use of an incorrect octane fuel may contribute to the Formation of deposits in the converter, which can harm the catalyst. Use only the octane recommended in the owners manual. Only OE spec spark plugs and wires should be used, as other brands may cause poor combustion and contribute to deposit Formation.
