High Pressure (Hp) Exhaust Gas RECIRCULATION (EGR)

WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

The High Pressure (HP) EGR valve is attached to the intake manifold. Exhaust gases are routed to the EGR valve from the exhaust manifold.

The EGR valve is cooled using engine coolant in the vehicle interior heating circuit. This protects the electrical components from overheating.

The EGR valve controls the amount of EGR exhaust gas flow depending on the Powertrain Control Module (PCM) map.

The design of the EGR pipe attachment to the inlet manifold helps mix the exhaust gasses with the main fresh air intake and also insulates the plastic intake manifold from the hot EGR pipe.

The exhaust gasses are passed through the EGR cooler before being passed through the EGR pipe to the intake manifold.

The EU4 market vehicles only have an HP EGR system.

On EU4 market vehicles, a separate EGR pipe attachment is used to connect between the intake manifold and the EGR cooler.
