Auxiliary power system for vehicle air conditioner and heater
First Claim
1. An integrated main and auxiliary power system for a vehicle, comprising:
- an engine compartment;
a main internal combustion engine disposed in said compartment for moving said vehicle;
air conditioning means including a compressor means disposed in said compartment for cooling the interior of said vehicle;
means disposed in said compartment for selectively connecting said main engine to said compressor means for driving the air conditioning means;
an auxiliary internal combustion engine disposed in said compartment for selectively operating said compressor means when said main engine is turned off;
shaft assembly means disposed in said compartment for coupling said auxiliary engine to selectively operate said compressor means;
a fuel tank for supplying fuel to the main and auxiliary engines;
a radiator disposed in said compartment adjacent to said main engine in fluid communication with the main engine for circulating coolant fluid to cool the main engine when the engine is operating;
means disposed in said compartment for connecting said auxiliary engine in fluid communication with said radiator for circulating coolant fluid to cool the auxiliary engine when the auxiliary engine is operating;
an exhaust pipe connected to said main engine for expelling exhaust gases emitted when the engine is operating; and
connector means for connecting said auxiliary engine to said exhaust pipe for expelling exhaust gases emitted when the auxiliary engine is operating.

Abstract
An auxiliary power system for an air conditioner and heater of a vehicle includes an auxiliary motor which is selectively connected by an electromagnetic clutch of a jack shaft assembly to drive the compressor of the vehicle'"'"'s air conditioner. The jack shaft assembly reduces the RPM of the auxiliary motor to an RPM suitable for operating the compressor. The auxiliary engine has a cooling system and an exhaust system which are respectively connected to the cooling and exhaust systems of the vehicle'"'"'s main engine. A baffle plate is provided at the point of connection to direct the flow of exhaust gases from the auxiliary engine into the exhaust system of the main engine. Solenoid actuated valves circulate coolant fluid from either the auxiliary or main engine to selectively heat water in a tank or to heat the interior of the passenger compartment of the vehicle. An auxiliary fan cools the condenser and radiator of the vehicle when the auxiliary engine is operating. Shroud doors are closed to direct the flow of air from the auxiliary fan when the main engine is not operating and are opened to bypass the auxiliary fan when the main engine is operating. The operational RPM of the auxiliary engine is maintained by a vacuum-actuated bellows which is spring-biased to control the movement of the throttle of the engine'"'"'s carburetor.

17. An integrated main and auxiliary power system for the air conditioner of a vehicle, comprising:
-
an engine compartment of the vehicle; an air conditioner for cooling the interior of the vehicle; a main engine disposed in said compartment for moving the vehicle and for selectively powering the air conditioner; a radiator means disposed in said compartment and having fluid connections with said main engine for circulating coolant fluid to cool the engine and thereby maintaining its temperature within a predetermined operating temperature range; an exhaust means for directing and expelling exhaust gases emitted by the operating main engine; an auxiliary internal combustion engine disposed in said compartment for selectively powering said air conditioner when said main engine is not operating; a jack shaft assembly means disposed in said compartment for coupling said auxiliary engine to selectively operate said air conditioner; a fuel tank for selectively supplying fuel to both the main engine and the auxiliary internal combustion engine; a connector means between said auxiliary engine and said radiator for circulating said coolant fluid to cool the operating auxiliary engine; and an auxiliary connector means between said auxiliary engine and said exhaust means for directing and expelling exhaust gases emitted by the operating auxiliary engine. - View Dependent Claims (18)

19. An integrated main and auxiliary power system for the air conditioner and heater of a vehicle, comprising:
-
an engine compartment within the vehicle; an air conditioner for cooling the interior of the vehicle; a heater for heating the interior of the vehicle; a main engine disposed in said compartment for moving the vehicle and for selectively powering the air conditioner; a radiator means disposed in said compartment and having fluid connections with said main engine for circulating coolant fluid to cool the engine and thereby maintain its temperature within a predetermined operating temperature range; an exhaust means for directing and expelling exhaust gases emitted by the operating main engine; an auxiliary internal combustion engine disposed in said compartment for selectively powering said air conditioner when said main engine is not operating; a fuel tank for selectively supplying fuel to both the main engine and the auxiliary internal combustion engine; a connector means between said auxiliary engine and said radiator means for circulating said coolant fluid to cool the operating auxiliary engine; valve means for selectively circulating coolant fluid from either the main engine or the auxiliary engine to heat the heater; and an auxiliary connector means between said auxiliary engine and said exhaust means for directing and expelling exhaust gases emitted by the operating auxiliary engine and for preventing exhaust gases of the operating main engine from moving into the auxiliary engine when the auxiliary engine is not operating. - View Dependent Claims (20)
