Abstract
A vehicle exhaust dissipation system includes a fan unit and one or more processors. A memory is communicably coupled to the one or more processors and stores a fan control module including computer-readable instructions that when executed by the processor(s) cause the processor(s) to, responsive to a determination that an ambient temperature is equal to or below a fan rotor activation temperature, control operation of the fan unit to generate an airflow directed into an exhaust gas exiting the vehicle from a vehicle exhaust opening.
Claims16
A vehicle exhaust dissipation system comprising:
- a fan unit;
- one or more processors;
- and
- a memory communicably coupled to the one or more processors and storing a fan control module including computer-readable instructions that when executed by the one or more processors cause the one or more processors to, responsive to a determination that an ambient temperature is equal to or below a fan rotor activation temperature, control operation of the fan unit to generate an airflow directed into an exhaust gas exiting a vehicle from a vehicle exhaust gas opening.
A vehicle exhaust dissipation system comprising:
- a fan unit including a rotor, the fan unit being structured to be positionable to generate an airflow into exhaust gas exiting an exhaust gas opening of a vehicle;
- one or more processors;
- and
- a memory communicably coupled to the one or more processors and storing a fan control module including computer-readable instructions that when executed by the one or more processors cause the one or more processors to:
- generate an airflow directed into the exhaust gas exiting the exhaust gas opening;
- responsive to an increase in a flowrate of the exhaust toward the exhaust opening, control operation of the fan unit to increase a rotation speed of the rotor;
- and
- responsive to a decrease in a flowrate of the exhaust toward the exhaust opening, control operation of the fan unit to decrease a rotation speed of the rotor.
A method of dispersing an exhaust gas exiting a vehicle exhaust gas opening, the method comprising a step of, responsive to a determination that an ambient temperature is equal to or below a fan rotor activation temperature, controlling operation of a fan unit to generate an airflow directed into the exhaust gas where the exhaust gas exits the vehicle exhaust gas opening.
