초록 ▼

An ignition spark advance system is disclosed which includes pulse generating means responsive to rotation of the shaft of an internal combustion engine for generating a first train of pulses including a first reference pulse and a plurality of additional pulses and a second train of pulses indicative of the angular position of the shaft of the engine. Timing means are provided for measuring the passage of a predetermined fixed time period after the occurrence of the first reference pulse in the first train of pulses. The relative spacing of the pulses in the first train of pulses and the relative spacing of the pulses in the second train of pulses are selected to be a function of the fixed time period and of each other such that, for any given engine speed, at substantially the angular position of the shaft of the engine at which firing of the spark plugs is desired for that given engine speed, the sum of the number of pulses in the first train of pulses which occurred during the fixed time period plus the number of pulses which have occurred in the second train of pulses is equal to a fixed number. The system also includes a counter, and a gate means responsive to the timing means for applying to the counter those pulses in the first train of pulses which occur during the predetermined fixed time period. The second train of pulses is also applied to the counter and when the count in the counter reaches the fixed number, the spark plugs in the engine are fired.

In an internal combustion-engine including an output shaft, spark plugs and an ignition-spark advances for controlling the firing of the spark plugs in which the desired spark advance curve is a non-linear function of engine speed, the improvement comprising, in combination: pulse generating means responsive to rotation of the output shaft of the engine for generating a first train of pulses including a first reference pulse and a plurality of additional pulses in which the pulses have a first predetermined relative spacing and a second train of pulses indicative of the angular position of the shaft of the engine relative to a predetermined angular position in which the pulses have a second predetermined relative spacing, in which at least one of the first predetermined relative spacing of the pulses in the first train of pulses and the second predetermined relative spacing of the pulses in the second train of pulses is a non-linear relative spacing; timing means for measuring the passage of a predetermined fixed time period after the occurrence of the first reference pulse in the first train of pulses; the first predetermined relative spacing of the pulses in the first train of pulses and the second predetermined relative spacing of the pulses in the second train of pulses being a function of the fixed time period measured by the timing means and of each other such that, for any given engine speed, at substantially the angular position of the shaft of the engine at which firing of the spark plugs is indicated by the spark advance curve for that given engine speed, the sum of the number of pulses in the first train of pulses which ocCurred during the fixed time period measured by the timing means plus the number of pulses which have occurred in the second train of pulses is equal to a fixed number; a counter; gate means responsive to the timing means for applying to the counter those pulses in the first train of pulses which occur during the predetermined fixed period; means for applying the second train of pulses to the counter; and means responsive to the count in the counter reaching a predetermined count equal to the fixed number for firing the spark plugs in the engine.
