Exhaust, Catalytic Converters, Diesel Particulates Filters

SAFETY - QUALITY - CONVENIENCE

VALUE FOR MONEY

Exhaust systems are made up of complex parts designed to protect the safety of the vehicle’s occupants, ensuring that they do not become exposed to harmful exhaust gases.

The exhaust system along with the catalytic converter also protects the environment from the same harmful gases.

To ensure your safety and that of the environment, we at Ellis Autos Ltd offer a free of charge no obligation check.

Exhaust System

While the only visible part of a car’s exhaust system is usually the tailpipe, it is actually much more extensive than that. A complex series of pipes and chambers underneath the main body of your vehicle often makes it difficult to visually notice potential problems. Although most exhaust problems can be diagnosed by listening out for unfamiliar sounds, other signs include rusting and smoke coming from the exhaust pipe. Exhaust damage can occur when driving over speed bumps or low kerbs as the exhaust system is usually the lowest part of the vehicle and may scrape on the ground.

Catalytic Converters

The catalytic converter or “Cat” is a mechanical device which is generally fitted to the vehicle's exhaust system. It reduces the harmful emissions created in the engine from the petrol being burnt prior to the gases passing through the exhaust system and entering the atmosphere. The main purpose of a catalytic converter is to reduce the harmful exhaust emissions.

The Cat reduces the harmful exhaust gases through a chemical reaction. It reacts with the harmful pollutants in the exhaust gases and turns them into less harmful gases. The catalytic converter consists of a special catalyst. The catalyst housing consists of a honeycomb core which is coated with precious metals such as platinum, palladium and rhodium which create the chemical reactions with the engine’s exhaust gases. They reduce the toxic contents of the gases and turn them into carbon dioxide and water. This is all designed to protect the environment.

Diesel Particulate Filters

If you own a diesel car, you probably have a diesel particulate filter. However, you may not know exactly what this is or how to maintain it.

Diesel particulate filters have been fitted to diesel fuel cars for almost two decades now - but if not maintained, or if tampered with there could be serious consequences for your car and the environment.

A diesel particulate filter (DPF) is a filter that captures and stores exhaust soot in order to reduce emissions from diesel cars.

But because they only have a finite capacity, this trapped soot periodically has to be emptied or 'burned off' to regenerate the DPF.

This regeneration process cleanly burns off the excess soot deposited in the filter, reducing the harmful exhaust emission and helps to prevent the tell-tale black smoke you used to see from diesel vehicles, particularly when accelerating.

Legislation introduced in 2009 to help lower car CO2 emissions effectively made DPFs mandatory on most diesel cars, vans and lorries.
