Systems and methods for air assisted injection of a reductant into an aftertreatment system

An aftertreatment system for an internal combustion engine, the aftertreatment system comprising:

• a turbocharger comprising:
• a compressor configured to receive air from an air source;
• and
• a turbine configured to receive exhaust from the internal combustion engine;
• an intake conduit configured to receive compressed air from compressor;
• an intake manifold configured to receive a first portion of the compressed air from the intake conduit and to provide the first portion of the compressed air to the internal combustion engine;
• an air delivery line configured to receive a second portion of the compressed air from the intake conduit separate from the intake manifold;
• and
• a housing configured to receive the second portion of compressed air from the air delivery line and to receive the exhaust from the turbine.

An aftertreatment system for an internal combustion engine having a turbocharger with a compressor and a turbine, the aftertreatment system comprising:

• an intake conduit configured to receive compressed air;
• an air delivery line coupled to the intake conduit and structured such that a first portion of the compressed air bypasses the air delivery line and a second portion of the compressed air is diverted into the air delivery line;
• and
• a housing structured to receive the second portion of compressed air from the air delivery line and to separately receive exhaust.
