1. A system, comprising:
- an intercooler positioned in an intake passage downstream of a turbocharger compressor configured to provide compressed intake air to an engine;
an exhaust gas recirculation (EGR) system including an EGR cooler defining at least a portion of an EGR passage and communicating with a mixing region where exhaust gas mixes with the compressed intake air;
a condensate collector fluidly coupled to the EGR cooler to collect condensate from the EGR cooler, the condensate collector positioned within the EGR cooler; and
a drain line coupled to the condensate collector, the drain line having an outlet fluidically coupled downstream of a turbocharger turbine.

Abstract
Various methods and systems are provided for managing condensation. In one example, a system comprises an engine; an intercooler positioned in an intake passage downstream of a first turbocharger compressor; an exhaust gas recirculation (EGR) system including an EGR cooler defining at least a portion of an EGR passage and communicating with a mixing region where exhaust gas mixes with the compressed intake air; a condensate collector fluidly coupled to the EGR cooler to collect condensate from the EGR cooler, the condensate collector positioned within the EGR cooler; and a drain line coupled to the condensate collector, the drain line having an outlet fluidically coupled to a turbocharger turbine outlet.
