SELECTIVE SUPPLYING OF AIR FROM AN AIR SUPPLY TO REDUCE AIR CONSUMPTION

摘要

Systems for reducing air consumption for aftertreatment systems by selectively supplying air from an air supply may selectively control a valve to enable or disable air supplied to a dosing module. A system may include an air supply, a dosing module, a valve, and a controller. The dosing module may be in selective fluid communication with the air supply. The valve may be configured to selectively supply air from the air supply to the dosing module. The controller may be configured to interpret a parameter indicative of a temperature of a component of an exhaust system and selectively operate the valve responsive to the interpreted parameter indicative of the temperature and a predetermined threshold value.
