Abstract
An ignition timing control system for an internal combustion engine including a throttle position sensor and a translational mechanism for transmitting movement of the throttle valve into a desired movement of the throttle position sensor so as to achieve variations in the spark advance angle without necessitating reconfiguration or recalibration of the ignition circuit.
Claims7
An ignition control system for an internal combustion engine having an engine speed controlling element moveable through a predetermined range for controlling engine speed, position sensing means for sensing the position of said speed controlling element and an ignition circuit for controlling ignition timing including arithmetic advancing means moveable in a predetermined range for controlling the ignition timing in response to a signal from said position sensing means, the improvement comprising motion translating means for translating the movement of said speed controlling element of a magnitude into movement of said position sensing means at a different magnitude.
An ignition control system for an internal combustion engine having an engine speed controlling element moveable through a predetermined range for controlling engine speed, position sensing means for sensing the position of said speed controlling element and an ignition circuit for controlling ignition timing including arithmetic advancing means moveable in a predetermined range for controlling the ignition timing in response to a signal from said position sensing means, the improvement comprising a linkage system for translating the movement of said speed controlling element into movement of said position sensing means at a predetermined ratio.
