EGR Delete

Exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in petrol/gasoline and diesel engines.

EGR works by re circulating a portion of an engine’s exhaust gas back to the engine cylinders. This dilutes the O2 within the incoming air stream and provides gases, inert to combustion, to act as absorbents of combustion heat in order to reduce peak in-cylinder temperatures. NOx is produced in a narrow band of high cylinder temperatures and pressures.

However, the valves can become clogged with carbon deposits, causing them to fail or stick, thereby causing error codes and the vehicle to not run correctly. Our solution is a simple and effective method of improving the efficiency. Topgear Tuning’s software disables the EGR valve, and results in lowered engine temperatures, improved throttle response and better economy.  It can also increase engine life by reducing oil contamination and carbon deposits.
