An auxiliary engine generates electricity through an alternator, to charge the vehicle battery and selectively run an electric motor for air conditioning when the vehicle's primary engine is not operating. Operation of the electric motor produces rotation of the drive shaft of the vehicle's air conditioning compressor, the output shaft of the electric motor being connected via a centrifugal clutch, and a drive belt on a pulley integral to the clutch, to a pulley bolted directly to the drive shaft of the compressor. There is no use made of the vehicle's existing electromagnetic clutch at the compressor location, i.e. it remains disengaged when the auxiliary system is operating, and is engaged only when air conditioning is called for in normal vehicle operation, i.e. when the primary engine is running. The electricity generated by the auxiliary engine can also be used to operate other accessories, if desired, such as lighting, televisions, VCRs, refrigerators and other like accessories.

1. An auxiliary system for a vehicle having an air conditioning system with an air conditioning compressor with a drive shaft normally driven by a primary engine of the vehicle via an electromagnetic clutch, controlled by air conditioning controls of the vehicle said auxiliary system comprising:an electric motor;a one way clutch and pulley on an output shaft of said electric motor, said one way clutch acting such that rotation of said electric motor output shaft produces rotation of said pulley but rotation of said pulley does not produce rotation of said electric motor output shaft;a pulley mounted directly on the drive shaft of said air conditioning compressor;a drive belt between said pulleys; andcontrol means for engaging said electric motor only when said primary engine is not operating and when air conditioning is called for by air conditioning controls of said vehicle, whereby said electric motor then rotates said one way clutch and pulleys and thereby drives said air conditioner compressor, said control means comprising a power diversion circuitry which routes power from said air conditioning controls of said vehicle to said electromagnetic clutch in normal operation of said vehicle, and away from said electromagnetic clutch and instead to said a means for switching connected to electric motor when said auxiliary system is engaged. 2. An auxiliary system as in claim 1, wherein said one way clutch on said output shaft of said electric motor is a centrifugal clutch. 3. An auxiliary system as in claim 1, further comprising an electric cooling fan operable for selectively cooling air conditioning fluid from said air conditioning system. 4. An auxiliary system as in claim 1, further comprising an auxiliary power source to generate electricity to charge a battery of the vehicle battery, for operation of at least one of said electric motor and vehicle accessories. 5. An auxiliary system as in claim 4, wherein said one way clutch on said output shaft of said electric motor is a centrifugal clutch. 6. An auxiliary system as in claim 4, further comprising an electric cooling fan operable for selectively cooling air conditioning fluid from said air conditioning system. 7. An auxiliary system as in claim 4, wherein said auxiliary power source is selected from the group consisting of a small gasoline motor, a small diesel motor, an electric motor powered by solar cells, and an electric motor powered by connection to an electrical outlet. 8. An auxiliary system as in claim 1, wherein said power diversion circuitry comprises a relay for said routing of power to said electromagnetic clutch in normal operation of said vehicle, and away from said electromagnetic clutch and instead to said means for switching connected to electric motor when said auxiliary system is engaged. 9. An auxiliary system as in claim 2, wherein said power diversion circuitry comprises a relay for said routing of power to said electromagnetic clutch in normal operation of said vehicle, and away from said electromagnetic clutch and instead to said means for switching connected to electric motor when said auxiliary system is engaged. 10. An auxiliary system as in claim 3, wherein said power diversion circuitry comprises a relay for said routing of power to said electromagnetic clutch in normal operation of said vehicle, and away from said electromagnetic clutch and instead to said means for switching connected to electric motor when said auxiliary system is engaged. 11. An auxiliary system as in claim 4, wherein said power diversion circuitry comprises a relay for said routing of power to said electromagnetic clutch in normal operation of said vehicle, and away from said electromagnetic clutch and instead to said means for switching connected to electric motor when said auxiliary system is engaged. 12. An auxiliary system as in claim 5, wherein said power diversion circuitry comprises a relay for said routing of power to said electromagnetic clutch in normal opera tion of said vehicle, and away from said electromagnetic clutch and instead to said means for switching connected to electric motor when said auxiliary system is engaged. 13. An auxiliary system as in claim 6, wherein said power diversion circuitry comprises a relay for said routing of power to said electromagnetic clutch in normal operation of said vehicle, and away from said electromagnetic clutch and instead to said means for switching connected to electric motor when said auxiliary system is engaged. 14. An auxiliary system as in claim 7, wherein said power diversion circuitry comprises a relay for said routing of power to said electromagnetic clutch in normal operation of said vehicle, and away from said electromagnetic clutch and instead to said means for switching connected to electric motor when said auxiliary system is engaged.
