A widely adopted route to reduce NOx emissions is Exhaust Gas Recirculation (EGR). This involves recirculating a controllable proportion of the engine’s exhaust back into the intake air. A valve is usually used to control the flow of gas, and the valve may be closed completely if required.
EGR SOLUTION
Refined Tuning have a very advanced solution for EGR. EGR valves can become clogged with carbon deposits, causing them to fail or stick, which in turn leads to error codes and poor running. We have developed a sophisticated solution to disable EGR, a simple and effective method of improving the efficiency of your engine.
