Title: Selective speed limiting apparatus for internal combustion engine

Patent ·
OSTI ID:6514648

This patent describes a system for selectively inhibiting ignition above a preselected engine speed for an internal combustion engine having a permanent magnet alternator. The system comprises: means for providing an electrical input which varies in a predetermined manner with the speed of the output of the permanent magnet alternator; control means adapted to control the ignition of the engine. The control means includes means for inhibiting ignition responsive to a control signal; means for providing the control signal responsive to the electrical input means and to at least one of a direct current voltage. Ground and open circuit inputs thereby selectively inhibit ignition responsive to the speed of the engine; and wherein the electrical input means is responsive to the peak voltage of the alternator.
