An air intake system is disclosed. The air intake system may have an air box. The air box may be configured to receive air from an ambient. The air intake system may also have a filter assembly disposed within the air box. The filter assembly may be configured to clean the air. In addition, the air intake system may have a duct. The duct may have a first duct end configured to receive the air exiting the filter assembly. The duct may also have a second duct end configured to deliver the air to the engine. The second duct end may be located at a gravitationally higher position than the first duct end.

Air intake system for an engine

The present disclosure is directed to an after-treatment device. The after-treatment device may have a center plenum configured to be fluidly connected to an engine. The after-treatment device may also have a filter bank having a plurality of filter assemblies. Each filter assembly may have an inlet fluidly connected to the center plenum. The inlet may be oriented orthogonal to the center plenum. Each filter assembly may also have an outlet. Further, the after-treatment device may have an exhaust plenum fluidly connected to the outlet. The exhaust plenum may be oriented orthogonal to the outlet. The exhaust plenum may also have an outer wall disposed parallel to and located at a predetermined distance from the outlet.

After-treatment device

An exhaust system for a machine is disclosed. The exhaust system may have a diffuser configured to receive exhaust from an engine. The exhaust system may further have a plurality of dosers associated with the diffuser and configured to inject fuel into the diffuser. The exhaust system may also have a controller configured to selectively control an amount of fuel injected by each of the plurality of dosers based on a velocity of the exhaust adjacent to each doser. In addition, the exhaust system may have an after-treatment component fluidly connected downstream of the diffuser and configured to heat the exhaust by oxidizing the injected fuel.

Exhaust system having multiple dosers

A heater tube for an exhaust system is disclosed. The heater tube may have an open end to receive heated exhaust from a pre-heater. The heater tube may have a closed end located opposite the open end. The heater tube may also have an outer surface extending from the open end to the closed end. The heater tube may further have a fin attached to the outer surface. In addition, the heater tube may have an opening disposed on the outer surface to discharge the heated exhaust.
