Air intake assembly for a vehicle

A truck comprising:

• a chassis supported by a plurality of wheels;
• an engine assembly operably connected to at least one of the wheels and configured to transfer power to the at least one of the wheels;
• an operator cab supported by the chassis;
• an air intake assembly connected to the engine assembly and configured for supplying air to the engine assembly, the air intake assembly comprising:
• an air intake configured to intake ambient air, wherein the air intake is located behind the operator cab;
• a heater box configured to be positioned adjacent a component of the truck that operates at higher temperature than the ambient air, the heater box comprising a chamber configured to capture heated air that is heated by the component;
• a valve in communication with the air intake and the heater box, wherein the valve is configured for intaking ambient air from the air intake, and wherein the valve is located behind the operator cab;
• an extraction conduit connecting the heater box to the valve such that the valve is configured for intaking the heated air from the heater box through the extraction conduit, wherein the extraction conduit is located behind the operator cab and extends behind the operator cab to connect the heater box to the valve;
• and
• an output conduit extending away from the valve to deliver air output from the valve to the engine assembly, wherein the output conduit is located behind the operator cab and extends behind the operator cab away from the valve,
• wherein the valve is configured to allow incremental mixing of the ambient air from the air intake and the heated air from the heater box and to deliver mixed air through the output conduit to the engine assembly.

An air intake assembly for a vehicle comprising:

• an air intake configured to intake ambient air;
• a heater box configured to be positioned adjacent a component of the vehicle that operates at higher temperature than the ambient air, the heater box comprising a chamber configured to capture heated air that is heated by the component;
• a two-way inlet valve box in communication with the air intake and the heater box, wherein the two-way inlet valve box is configured for intaking ambient air from the air intake, and wherein an extraction conduit connects the heater box to the two-way inlet valve box such that the two-way inlet valve box is configured for intaking the heated air from the heater box, wherein the air intake and the two-way inlet valve box are configured to be positioned along a first lateral side of the vehicle, and a connection between the extraction conduit and the heater box is configured to be positioned along a second lateral side of the vehicle opposite the first lateral side, and wherein the extraction conduit extends from the second lateral side to the first lateral side to connect to the two-way inlet valve box;
• an output conduit extending away from the valve to deliver air output from the valve box;
• an air cleaner connected to the output conduit and configured to clean the air output from the output conduit;
• and
• a valve control connected to the valve box and configured to control operation of the valve box to allow incremental mixing of the ambient air from the air intake and the heated air from the heater box and to deliver mixed air through the output conduit to the air cleaner.
