Catalytic Converter

Details and Specification of Catalytic Converter

A catalytic converter acts as an exhaust emission controller installed in automotive machines. It performs a redox reaction by processing the toxic pollutants and gases from the internal combustion engine and converting them into less-toxic pollutants by catalyzing by reduction reaction. The catalytic converters are also popular as "cats" or "cat-cons". The device's function is to reduce air pollution, make and turn them into steam. As the name suggests, the device has a catalyst that converts hazardous gases into less dangerous gases at high temperatures. A catalyst is a chemical that accelerates the process of a chemical reaction without changing its properties. The Nobel metal such as platinum, palladium, or rhodium used as a catalyst. It requires about 800 degrees Fahrenheit (426 °C) to operate, so the product is placed closer to the engine.

The device looks like a metallic box with two pipes coming out of it, which act as input and output for the gases. It is attached to the outer end of a car's exhaust pipe. The inlet brings in polluted fumes from the engine's cylinders where it reduces power. The outlet is attached to the tailpipe that acts as an exhaust. When gases from the engine’s fumes pass over the catalyst, a chemical reaction takes place. That breaks apart the pollutant gases converting them into less harmful gases, which are safe to blow out into the environment.

Types of Catalytic Converter

At Shilpa enterprises, we offer the following types of catalytic converters.

Three-Way Catalytic Converter for 2-Wheeler

The three-way converter performs to control the emission of nitric oxide (NO) and nitrogen dioxide (NO2) along with performing oxidation of carbon monoxide and hydrocarbons. It means that the three-way converter performs three tasks simultaneously, i.e., reduction of nitrogen oxides into nitrogen and oxygen, oxidation of carbon monoxide into carbon dioxide, and oxidation of non-burned hydrocarbons into carbon dioxide and water.

The chemical reaction of reduction of nitrogen oxides into nitrogen and oxygen is :

2NOx → xO2 + N2

The chemical reaction of oxidation of carbon monoxide into carbon dioxide is:

2CO + O2 → 2CO2

The chemical reaction of Oxidation of non-burned hydrocarbons to carbon dioxide and water is

CxH2x+2 + [(3x+1)/2] O2 → xCO2 + (x+1) H2O

The product is suitable for two-wheeler. It supports an engine capacity of 150cc, 300cc, and 1400cc. The type of catalyst used in the product is the three-way catalyst (noble metal catalyst) suitable for petrol or gasoline fuel. The wash coat in the product is aluminum oxide, rear earth ct/zr, and noble metal. The operating temperature range of the product is 25 ˚C to 800 ˚C, and the substrate MOC is used in metal chrome alloy and ceramic honeycomb. The product has a cell density of 400cpsi and is available in 150cc and 300cc, especially for a two-wheeler.

Diesel Catalytic Converter

The Diesel Oxidation Catalyst (DOC) is the converter used in compression-ignition, i.e., diesel engines. It functions by using oxygen (O2) that is present in the exhaust gas stream to convert carbon monoxide (CO) into carbon dioxide (CO2) and hydrocarbons (HC) to water (H2O) and carbon dioxide (CO2). The diesel exhaust contains high levels of particulate matter, i.e., soot, consisting of a considerable part of elemental carbon that the product in the form of DPF converts efficiently.

The product is suitable for four-wheeler automobile as it works with diesel. The catalyst used in the product is universal doc type, which is in a 3:1 ratio. The engine capacity that the product supports is a 1400cc or 1.4-liter engine. Aluminum oxide, rear earth ct/zr, and noble metal use as a wash coat. The operating temperature of the equipment ranges from 25 ˚C to 800 ˚C. The product has two ceramic honeycomb substrates and a cell density of 400 cpsi.

Catalytic Converter for Four Wheeler

It is suitable for a four-wheeler automobile application. It has an engine capacity of 1400cc or a 1.4-liter engine. The fuel type it supports is petrol or diesel for four-wheeler; however, users must avoid using lead-infused petrol (Gasoline). It uses a universal type catalyst and has a ratio of 15:1. The product uses two ceramic honeycomb substrates and has a cell density of 400cpsi.

Applications of Catalytic Converter

Catalytic converters are primarily suitable for exhaust systems of automobiles. However, it is also applicable to electrical generators, forklifts, trucks, buses, mining equipment, motorcycles, locomotives, and ships. Some wood stoves also utilize the equipment to control emissions.

How to use Catalytic Converter?

The installation of the product occurs at the rear end of the automobile form where the exhaust works.

Make sure that its fittings should be correctly done.

Safety Measures of Catalytic Converter

Use unleaded fuel, as the lead in conventional fuel deteriorates the catalyst and prevents it from receiving the pollutants in exhaust gases. Avoid using diesel and petrol that consists of sulfur, phosphorus, manganese, and silicon.
