Abstract
Abstract A magnetic pickup type electrical signal generator is mounted in cooperative relationship with the movable member of each fuel injector of an associated fuel injected-spark ignited internal combustion engine. In response to the initiation of actuation of the movable member to inject fuel into the combustion chamber of the corresponding engine cylinder, the magnetic pickup signal generator produces an output signal to which an associated electronic ignition system is responsive to produce an ignition spark creating potential. Each ignition spark creating potential is directed to the spark plug of the engine cylinder into which fuel is being injected by the actuated fuel injector.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
171 words
An ignition system for use with a fuel injected-spark ignited internal combustion engine of the type having a spark igniting device for each cylinder thereof, comprising: a fuel injector having a movable member corresponding to each cylinder of an associated internal combustion engine for injecting fuel into the combustion chamber of the said cylinder to which it corresponds upon the actuation of said movable member; means corresponding to and in cooperative relationship with the said movable member of each said fuel injector, each said means being responsive to the initiation of actuation of the corresponding said movable member to inject fuel into the combustion chamber of the said cylinder to which said fuel injector having said actuated movable member corresponds for producing an output electrical signal of a selected polarity; circuit means responsive to each said electrical signal for producing an ignition spark creating voltage; and means for directing said ignition spark creating voltage to the said spark igniting device of the said cylinder of said engine next to be fired.
Claim 2
Dependent Claim
171 words
An ignition system for use with a fuel injected-spark ignited internal combustion engine of the type having a spark igniting device for each cylinder thereof, comprising: a fuel injector having a movable member corresponding to each cylinder of an associated internal combustion engine for injecting fuel into the combustion chamber of the said cylinder to which it corresponds upon the actuation of said movable member; means corresponding to and in cooperative relationship with the said movable member of each said fuel injector, each said means being responsive to the initiation of actuation of the corresponding said movable member to inject fuel into the combustion chamber of the said cylinder to which said fuel injector having said actuated movable member corresponds for producing an output electrical signal of a selected polarity; circuit means responsive to each said electrical signal for producing an ignition spark creating voltage; and means for directing said ignition spark creating voltage to the said spark igniting device of the said cylinder of said engine next to be fired.
