Discovery 2 EGR Valves
Discovery 2 EGR (Exhaust Gas Recirculation) valves reduce emissions by recirculating exhaust gases back into the combustion process. These components are particularly important on Td5 diesel engines, where proper EGR operation affects performance, fuel economy, and emissions compliance.
EGR System Operation
EGR valves control exhaust gas recirculation based on engine load and operating conditions. Electronic control systems monitor engine parameters and adjust EGR operation accordingly. Proper function reduces combustion temperatures and NOx emissions whilst maintaining performance. Carbon buildup from recirculated gases can cause valve sticking and poor operation. Regular cleaning prevents performance problems and maintains compliance. Exhaust systems work with EGR components, whilst fuel systems affect EGR operation.
