Auxiliary power system for vehicle air conditioner and heater

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.

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.
