Here at Essex Tuning we have an advanced solution for deleting/removing the EGR valve from the vehicles ECU. We remove these valves as they can become clogged with carbon deposits, causing them to fail or stick, thereby causing diagnostic trouble codes (DTC) and the vehicle not to run correctly. Our software solution to disable the EGR valve is a simple and effective method of improving the efficiency of your engine.
BENEFITS OF EGR REMOVAL?
Modern engines recirculate their exhaust gases back through the engine to reduce the emissions. The downside of this is that exhaust fumes containing carbon are constantly being recirculated through the engine and over time can cause a build-up of carbon in the intake manifold etc.
These carbon build-ups contribute to the failure of the EGR system itself, and the replacement of EGR valves can be expensive. There is also the cause for concern that high mileage vehicles could suffer complete engine failure with a faulty EGR Valve.
Removal of the EGR system by banking off the exhaust input and reprogramming of the ECU results in lowered engine temperatures, improved throttle response and economy and also can lengthen engine life by reducing oil contamination and carbon deposits.
HOW EGR WORKS?
The EGR theory works by sending a small part of inactive gas exhaust back into a vehicle’s cylinders, hence eject negligible toxins into the environment. This reduces the heat of combustion yet the same amount of pressure is still applied to this piston while reducing the amount of excess oxygen prior to combustion. A few studies conducted on diesel engines demonstrate that the portion of nitrous oxide gas emissions is definitely reduced through the use of EGR, however concentrations of smoke density can actually increase. Thus there seem to be pluses and minuses depending on what’s important to you in your specific vehicle
Usually, an engine recirculates exhaust gas by piping it from the exhaust manifold to the inlet manifold. This design is called external EGR. A control valve (EGR Valve) within the circuit regulates and times the gas flow. Some engines incorporate a camshaft with relatively large overlap during which both the intake valve and the exhaust valve are open, thus trapping exhaust gas within the cylinder by not fully expelling it during the exhaust stroke.
IS EGR DELETE LEGAL?
It is not illegal to remove the EGR from your vehicle, however it is an offence under the Road vehicles (Construction and Use) Regulations (Regulation 61a(3))1 to use a vehicle which has been modified in such a way that it no longer complies with the air pollutant emissions standards it was designed to meet and is now an instant fail on a MOT.
