  • No-idle heating of a motor vehicle interior and engine pre-heat using engine coolant
    Patent number: 7793856
    Abstract: When a truck engine (12) is not running, an auxiliary coolant heater (32) can heat engine coolant and pump it through an occupant compartment heater (16). A coolant flow control system (10), including a valve assembly (84), associates the auxiliary heater (32) with both the occupant compartment heater (16) and engine (12) for selectively distributing heated coolant. When engine (12) has been running and is shut off, auxiliary heater (32) can be turned on and valve assembly (84) operated for occupant compartment heating while keeping the engine (12) warm. When the engine is cold, the auxiliary heater can be turned on and the valve assembly can be operated for engine pre-heating prior to starting.

  • Intake heater for HVAC fresh air intake
    Patent number: 7717497
    Abstract: A vehicle having a cowl tray and a Heating, Ventilation, and Air Conditioning (HVAC) system is provided with one or more coolant-to-air heat exchangers near the intake opening of the HVAC system or attached to the cowl tray, in order to prevent an accumulation of snow and ice from blocking the flow of intake air into the HVAC system and interfering with the windshield wiper system. The accumulation of snow and ice in the HVAC intake is a problem commonly experienced by vehicles having the HVAC intake located near the base of the vehicle windshield, due to turbulent precipitation.
