Function
The additional exhaust-gas recirculation cooler is arranged above the exhaust manifold and directly screwed to the exhaust manifold. The additional exhaust-gas recirculation cooler is connected to the cooling circuit.
The exhaust gas travels directly from the exhaust manifold to the additional exhaust-gas recirculation cooler. The outlet of the supplementary EGR cooler is connected by a pipe to the inlet of the EGR valve. The exhaust passes as normal into the normal EGR cooler via the EGR valve.
