EGR Valves (Exhaust Gas Recirculation)

The EGR system is a reliable and proven method of emission control for both petrol and diesel applications. As a result of a controlled reduction of oxygen content in the combustion process by the EGR valve, the combustion temperature and pressure is reduced, allowing for a reduction in NOx (Nitrogen Oxides) concentrates emitted to the environment.

Since harmful NOx are mainly produced at high temperatures, it is possible with the EGR system to reduce these pollutants by up to 50% and also resulting in reducing soot particulates on diesel engines by up to 10%. Note that the EGR is only activated at defined operation stages that vary with specific vehicles.
