  • Patent number: 11117443
    Abstract: An HVAC module for an automotive vehicle includes a housing defining an air inlet, an upper front zone outlet, a lower front zone outlet, and a rear zone air outlet. An evaporator and a heater downstream of the evaporator are disposed in the housing. The air inlet of the housing is divided by a first divider into an OSA portion exclusively receiving outside air and a REC portion exclusively receiving recycled air. Each of the evaporator and the heater has a respective OSA portion receiving the outside air and a REC portion receiving the recycled air entering the HVAC module through the inlet. A second divider between the evaporator and the heater directs the outside air from the REC portion of the evaporator to the REC portion of the heater. Two temperature doors control access of separate partial streams of the recycled air from the evaporator to the heater.

  • Patent number: 11060487
    Abstract: An improved evaporative emission mitigation system for a motor vehicle includes a canister filled with an adsorbent material connected to a membrane module. The membrane module contains a membrane that separates gaseous hydrocarbons from inert air components within fuel vapor generated by the evaporation of fuel due to the heating of the motor vehicle. The gaseous hydrocarbons separated by the membrane are returned to the canister, where they will again be adsorbed by the adsorbent material. The inert air components are vented from the membrane module into the open atmosphere outside of the motor vehicle.
