Exhaust RepairExhaust Systems

 

The main purpose of the exhaust system is to silence the noise from the engine.

 

Fitted in your exhaust system is a catalytic converter, which is very important for the reduction of emissions from the car.

 

Exhaust systems can sometimes be repaired and we have a welding plant in house to cater for this. Alternatively, parts can be replaced if required.

 

We would need to check the exhaust system to diagnose where the problem is occurring which would require you to call down to us and get a free check of system.

Catalytic Converters

Oxygen Sensors are used in modern automobiles to control the fuel and ignition systems to optimize a car's performance in the areas of emissions and fuel economy. Sensors are located before and after the catalytic converter to check on the amount of oxygen in the exhaust. The sensor sends signals to the car's on-board computer, which then can adjust several variables, including air/fuel ratio and timing, in order to bring the engine into the optimum operating range

Catalytic Converters: How they work

 

How the Diesel Engine Exhaust System Reduces  Emissions
A diesel particulate filter, sometimes called a DPF, is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine. Wall-flow diesel particulate filters usually remove 85% or more of the soot, and can at times (heavily loaded condition) attain soot removal efficiencies of close to 100%. A diesel-powered vehicle equipped with a functioning filter will emit no visible smoke from its exhaust pipe.
In addition to collecting the particulate, a method must exist to clean the filter. Some filters are single-use (disposable), while others are designed to burn off the accumulated particulate, either through the use of a catalyst (passive), or through an active technology, such as a fuel burner which heats the filter to soot combustion temperatures, through engine modifications (the engine is set to run a certain specific way when the filter load reaches a pre-determined level, either to heat the exhaust gases, or to produce high amounts of NOx, which will oxidize the particulates at relatively low temperatures), or through other methods. This is known as "filter regeneration
