Catalytic Converter and Mufflers description Three way catalytic converter manufactured with a stainless-steel body, aluminum pipe and heat shields, that provide you peace-of-mind with assured compliance by engineers who set the standard. Whether it’s universal or direct-fit, catalytic converters feature an optimal high-technology wash coat and OE-design precious metal load that deliver required reduction in tailpipe emissions to match vehicle application. Exhaust pipe catalytic converter the product makes full use of the coordinated effects of precious metals and rare earth composite oxides. The carbon monoxide CO, hydrocarbons HC, and nitrogen oxides NOX in the exhaust gas undergo oxidation/reduction, thereby converting them into non-toxic carbon dioxide, water and nitrogen.   HIGHER EFFICIENCY & QUALITY : Internal ceramic substrates contain ample metal catalysts and offer a larger surface area to fully react; Adopts stainless steel shell that highly resists heat, rust, and corrosion for longer service life, no worry about bending or melting. SUPERIOR TECHNOLOGY : Optimal high technology wash coat formulated to deliver superior performance. CONSISTENT PERFORMANCE : Utilizes a precise OE-style coating process to apply catalyst material to the substrate, providing consistent performance for assured emissions compliance STRONG AND DURABLE : Features thick OE-style flanges, hangers and brackets for strength and stainless-steel body with aluminum pipe and heat shields for durability

Three way catalytic converter refers to the conversion of harmful gases such as CO, HC and NOx from automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. The carrier part of the exhaust pipe catalytic converter is a piece of porous ceramic material, which is installed in a special exhaust pipe. It is called a carrier because it does not participate in the catalytic reaction itself, but is covered with a coating of precious metals such as platinum, rhodium, palladium and rare earths. It is the most important external purification device installed in the automobile exhaust system. The working principle of the Direct- Fit Three Way Catalytic is: when the high-temperature automobile exhaust passes through the purification device, the purifier in the three-way catalytic converter will enhance the activity of the three gases CO, hydrocarbons and NOx, and promote it to undergo a certain oxidation-reduction chemical reaction, in which CO oxidized into a colorless, non-toxic carbon dioxide gas at high temperature; Hydrocarbons are oxidized to water (H2O) and carbon dioxide at high temperatures; NOx is reduced to nitrogen and oxygen. Three harmful gases become harmless gases, so that car exhaust can be purified. Assuming there's still oxygen available, the air-fuel ratio is reasonable.

The running board is a kind of auto parts used to decorate the threshold of the car, protect the car body and beautify the car body, which belongs to a kind of car modification supplies. The side step is mainly installed on the side of the door of the anti-mud pad, 4 doors have. The shape of the car running board panel varies according to different models side steps for trucks 1, stainless steel material, smooth and bright appearance, simple installation, can play a certain anti-collision anti-collision function, but also a decorative element, simple and not simple; 2, fully matched with the car itself, to protect the threshold of easy to be scratched when getting on and off the car, improve the texture of the interior; To open the door and see such a piece of pedal, I feel at home. Advantages: One of the most obvious advantages of installing a welcome pedal is that it plays a decorative role in the car. Many welcome pedals have a connection, and the door will light up as soon as the door is opened, creating a feeling of home for those who get on the bus. Second. The welcome pedal can avoid shoes scratching the car threshold when getting on and off the car, and the paint of the car is damaged.
