Abstract

A system for aiding an engine in a vehicle includes an air duct operably disposed in the vehicle having a fresh air inlet for receiving fresh air, first outlet for exhausting air outside the vehicle, and second outlet for exhausting air inside a passenger compartment, a cool air conditioning device operably disposed in the duct to cool air as it passes thereby when in an “on mode”, a heater core operably disposed in the duct to continuously provide heat air as it passes thereby and remove heat from the engine. A first diverter is operably disposed in the duct for continuously diverting at least some of the heated air toward the first outlet when the cool air conditioning device is in an “on mode” and a second diverter is operably disposed in the duct for continuously diverting at least one fresh air or cool air toward one of the outlets.

Claims

1. A system for aiding in prevention of engine overheating in a vehicle, wherein liquid coolant is circulated between the engine where it picks up heat and a radiator where it surrenders its heat as it flows through the radiator with a portion of the liquid coolant routed to a heater core where it further surrenders heat, which includes:

an air duct system operably disposed in the vehicle having a fresh air inlet for receiving fresh air, first outlet means for exhausting air outside the vehicle, and second outlet means for exhausting air inside a passenger compartment of the vehicle;

a cool air conditioning device operably disposed in said duct system to cool air as it passes thereby when in an “

on mode”

;

a heater core operably disposed in relation to said duct system to continuously provide heat to said duct system and to heat air as it passes through said duct system and remove heat from said engine;

first diverter means operably disposed in said duct system for continuously diverting at least some of said heated air toward said first outlet means when said cool air conditioning device is in an “

on mode”

; and

second diverter means operably disposed in said duct system for continuously diverting at least one of fresh air and cool air toward one of said outlet means.

2. The system of claim 1, wherein said duct system includes third outlet means for exhausting air onto the engine and a third diverter means operably disposed in said duct system for continuously diverting at least one of fresh air and cool air toward one of said second outlet means and said third outlet means when said cool air conditioning device is in said “

on mode”

.

3. The system of claim 2, wherein at least one said diverter means cooperates to partially open to provide blended air temperature.

4. The system of claim 1, wherein said duct system includes third outlet means for exhausting air onto the engine and a third diverter means operably disposed in said duct system for continuously diverting at least one of fresh air and heated air toward one of said second outlet means and said third outlet means when said cool air conditioning device is in “

off mode”

.

5. The system of claim 4, wherein said first diverter means is equipped to divert heated air toward said second outlet means and said third outlet means when said cool air conditioning device is in an “

off mode”

.

6. The system of claim 4, wherein at least one said diverter means cooperates to partially open to provide blended air temperature.

7. The system of claim 1, wherein said first diverter means is equipped to divert heated air toward said second outlet means when said cool air conditioning device is in an “

off mode”

.

8. The system of claim 1, wherein said first diverter means is equipped to divert heated air toward said first outlet means when said cool air conditioning device is in an “

on mode”

.

9. The system of claim 1, wherein said second diverter means is equipped to divert heated air toward said first outlet means when said cool air conditioning device is in an “

on mode”

.

10. The system of claim 1, wherein said duct system includes an insulated portion to receive said heated air in a manner to maintain said heated air substantially insulated from one of said cooled air and said fresh air.

11. The system of claim 1, wherein at least one said diverter means cooperates to partially open to provide blended air temperature.
