Vehicle system with injection housing and turbocharger having motor

A vehicle system comprising:

• a turbocharger comprising:
• a turbine configured to receive exhaust from an engine-turbine exhaust conduit,
• a turbine shaft coupled to the turbine,
• a first motor coupled to the turbine shaft,
• a compressor configured to provide air to an engine-compressor air conduit, the engine-compressor air conduit configured to provide the air to an engine, and
• a compressor shaft coupled to the compressor, the compressor shaft rotatable independent of the turbine shaft;
• a controller configured to cause the first motor to rotate the turbine shaft;
• an injection housing directly coupled to the turbine or to a turbine-housing exhaust conduit that is directly coupled to the turbine, the injection housing being configured to receive the exhaust from the turbine or from the turbine-housing exhaust conduit;
• and
• a dosing module coupled to the injection housing, the dosing module comprising an injector configured to inject treatment fluid into the injection housing.

A vehicle system comprising:

• an engine comprising:
• a crankshaft,
• a cylinder-piston assembly configured to rotate the crankshaft, the cylinder piston assembly comprising a cylinder, and
• a fuel injector corresponding to the cylinder-piston assembly, the fuel injector configured to inject fuel into the cylinder;
• a turbocharger comprising:
• a turbine configured to receive exhaust from an engine-turbine exhaust conduit,
• a turbine shaft coupled to the turbine,
• a first motor coupled to the turbine shaft,
• a compressor configured to provide air to an engine-compressor air conduit, the engine-compressor air conduit configured to provide the air to the engine, and
• a compressor shaft coupled to the compressor and the crankshaft;
• a controller configured to (i) cause the first motor to rotate the turbine shaft and (ii) control fuel amount injected by the fuel injector based on a pressure of the air provided by the compressor to the engine via the engine-compressor air conduit;
• an injection housing directly coupled to the turbine or to a turbine-housing exhaust conduit that is directly coupled to the turbine, the injection housing being configured to receive the exhaust from the turbine or from the turbine-housing exhaust conduit;
• and
• a dosing module coupled to the injection housing, the dosing module comprising an injector configured to inject treatment fluid into the injection housing.
