System and methods for engine air path condensation management

A method for an engine having an exhaust coupled to a light off catalyst, comprising:

• routing air from an air compressor through a heat exchanger to a combustion chamber of the engine;
• collecting condensate formed in said heat exchanger;
• accumulating a portion of said compressed air in an accumulator;
• when said condensate contains a contaminate, coupling said condensate through a passage to said combustion chamber;
• and
• when an engine output is below a predetermined amount, coupling a part of said accumulated air through a passage into said combustion chamber to push said condensate into said combustion chamber.

A system, comprising:

• an engine having multiple combustion chambers, an air intake manifold and intake runners coupling said manifold to said intake runners, and an exhaust coupled to a light off catalyst;
• a turbocharger having a turbo coupled to said exhaust and a compressor driven by said turbo;
• a heat exchanger having an input connected to said compressor and an output coupled to said combustion chambers through said intake manifold and said intake runners;
• a reservoir connected to said heat exchanger and a plurality of passageways each connected between said reservoir and each of said intake runners to route condensate to said combustion chambers;
• an accumulator having an input coupled to said compressor and an output coupled to each of said passageways;
• and
• a controller controlling airflow from said accumulator through said passageways when the engine output is below a predetermined amount to force said condensate into each of said intake runners.
