Abstract: An air brake compressor supply fitting for an internal combustion engine having a turbocharger and an exhaust gas recirculation (EGR) system is located downstream of the turbocharger and upstream of where the exhaust gas is introduced into the intake air of the engine. The supply fitting can be integrated into an outlet manifold of a charge air cooler (CAC associated with the turbocharger or into an EGR mixer for mixing exhaust gas with the intake air of the engine at a location in the EGR mixer upstream from the location where the exhaust gas is introduced into the intake air of the engine.
