Abstract
Abstract A system is disclosed for starting an engine from a remote location utilizing a receiver for receiving a command signal from a remote location and generating an engine start signal in response thereto. The start signal actuates an energizing circuit which connects a potential source to the ignition system of the engine, and which, in response to control signals from a twostage time delay start mechanism, connects the potential source to the starter motor for the engine. A protection mechanism is coupled to the energizing circuit and disconnects the potential source from the ignition system, thereby stopping the engine, upon the occurrence of any one of a number of predetermined events including, ''''racing'''' of the engine; ''''grinding'''' of the engine without starting; or idling of the engine for a predetermined period of time. The system may further include a mechanism coupled to the energizing circuit for detecting that an operator is preparing to assume control of the engine following remote starting thereof, including means for establishing a time period within which the operator must assume proper manual control of the engine and in the absence of such control, disconnecting the potential source from the ignition system, thereby stopping the engine.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
206 words
A system for starting, from a remote location, a combustion engine having an ignition system, and having an electric starter motor, an electric generating device and a source of electric potential associated therewith, said system comprising: an energizing circuit coupled to a receiver to receive an engine start signal therefrom and including means for connecting said potential source to said ignItion system and said starter motor in response to said start signal to thereby energize the ignition system and the starter motor, said energizing circuit also being coupled to said generating device to receive an electric signal therefrom and including means for disconnecting said potential source from said starter motor in response to said electric signal to thereby de-energize said starter motor; a device for feeding fuel to said engine; a protection mechanism coupled to said energizing circuit and said fuel feed device and including an idle regulator mechanism for sequentially energizing and de-energizing said fuel feed device after the engine has started to thereby regulate the idle speed thereof, said protection mechanism further including means for disconnecting said potential source from said ignition system if said idle regulator mechanism does not deenergize said fuel feed device, to thereby stop the engine and prevent damage thereto.
Claim 2
Independent Claim
206 words
A system for starting, from a remote location, a combustion engine having an ignition system, and having an electric starter motor, an electric generating device and a source of electric potential associated therewith, said system comprising: an energizing circuit coupled to a receiver to receive an engine start signal therefrom and including means for connecting said potential source to said ignItion system and said starter motor in response to said start signal to thereby energize the ignition system and the starter motor, said energizing circuit also being coupled to said generating device to receive an electric signal therefrom and including means for disconnecting said potential source from said starter motor in response to said electric signal to thereby de-energize said starter motor; a device for feeding fuel to said engine; a protection mechanism coupled to said energizing circuit and said fuel feed device and including an idle regulator mechanism for sequentially energizing and de-energizing said fuel feed device after the engine has started to thereby regulate the idle speed thereof, said protection mechanism further including means for disconnecting said potential source from said ignition system if said idle regulator mechanism does not deenergize said fuel feed device, to thereby stop the engine and prevent damage thereto.
Claim 3
Dependent Claim
72 words
A system as recited in claim 1, wherein said idle regulator mechanism comprises a first time delay means for energizing the fuel feed device a first predetermined period of time after said engine start signal is received by said energizing circuit and a second time delay means for de-energizing the fuel feed device a second predetermined period of time after the fuel feed device is energized by said first time delay means.
Claim 4
Dependent Claim
49 words
A system as recited in claim 1, wherein said protection mechanism further includes back-up means for disconnecting said potential source from said ignition system if said fuel feed device or said starter motor is energized after the engine has started, to thereby stop the engine and prevent damage thereto.
Claim 5
Dependent Claim
50 words
A system as recited in claim 1, wherein said protection mechanism further includes means for disconnecting said potential source from said ignition system and said starter motor if the engine does not start within a predetermined period of the time after the starter motor is energized by said energizing circuit.
Claim 6
Dependent Claim
84 words
A system as recited in claim 1, further comprising a detection mechanism coupled to said energizing circuit and being operable to detect preparation by an operator to assume manual control of the engine, said detection mechanism including means for disconnecting said potential source from said ignition system if an operator does not assume proper manual control of the engine within a predetermined period of time after said preparation is detected, to thereby stop the engine and prevent an unauthorized operator from assuming control thereof.
Claim 7
Dependent Claim
59 words
A system as recited in claim 1, wherein said energizing circuit includes at least one time delay means coupled to said means for connecting the potential source to the starter motor to prevent the potential source from being connected to the starter motor for a predetermined period of time after the potential source is connected to the ignition system.
Claim 8
Dependent Claim
38 words
A system as recited in claim 1, wherein said energizing circuit is coupled to the fuel feed device and further includes means for energizing the fuel feed device before the potential source is connected to the starter motor.
Claim 9
Dependent Claim
40 words
A system as recited in claim 1, wherein said energizing circuit is coupled to the fuel feed device and further includes means for energizing the fuel feed device before and while the potential source is connected to the starter motor.
Claim 10
Dependent Claim
48 words
A system as recited in claim 1, wherein said protection mechanism further includes means for disconnecting the potential source from the ignition system a predetermined period of time after the engine has been started, to thereby prevent the engine from running unattended for a prolonged period of time.
Claim 11
Dependent Claim
49 words
System as cited in claim 1, wherein said protection mechanism further includes means for disconnecting the potential source from the ignition system when said start signal is applied to said system after the engine has started, to thereby permit an operator to stop the engine from a remote location.
