The straight answer in most cases is no. Many petrolheads out there decide that the catalytic converter is producing a severe blockage within the exhaust system that needs to be eradicated and therefore delete the cat from the system altogether, replacing it with a straight pipe. Although this ...
FixMyCar discusses what a catalytic converter is, how it can go wrong, and why it is often targeted by thieves.
As their name suggests, catalytic converters contain catalysts. A catalyst works by helping a chemical reaction to take place faster. So, let’s look at what happens in a three-way catalytic converter for a gasoline engine. Inside the catalytic converter are ceramic blocks, made up of thousands...
Catalytic converter theft Unfortunately, the precious metals within catalytic converters have seen spikes in prices over the last several years. This, coupled with the fact that the part can often be removed with just a few hand tools, has led to catalytic converter theft becoming an increasingly...
Types of Catalytic Converters: There are three different types of Cat-Cons. The first type is the oxidation catalyst. It reduces harmful pollutants such as carbon monoxide (CO) and fuel hydrocarbons (HC) in the exhaust. Simultaneously, it often uses a secondary air injection. However, the oxid...
When Were Catalytic Converters Required? As an integral part of your vehicle’s exhaust system, the catalytic converter is designed to reduce certain gases and pollutants emitted from the exhaust of vehicles equipped with an internal combustion engine. Since 1975, vehicles have needed a catalytic ...
catalytic converters use much better flowing matrix designs which also last longer. People who have gutted their catalytic converters or simply put in straight piping have indeed reported improved performance in the 5 to 10% range. If your aim is to extract every bit of power on track day, ...
While most commonly used in chemical reactions, catalysts also play roles in biological and environmental processes, such as in the action of enzymes or catalytic converters in vehicles. 13 What is the primary function of a catalyst in industrial processes? In industrial processes, a catalyst primar...
As for all catalytic converters, the large active surface area ensures efficiency, which is vital when high amounts of pollutants are to be converted in a fraction of a second. When a ceramic converter is due to be recycled, it is firstly cut open and the ceramic monolith is removed and ...
