ABSTRACT:
An electronic ignition system is disclosed for controlling as a function of a selected engine parameter the ignition instants of an internal combustion engine having at least one cylinder, a piston, a spark plug for effecting combustion in the cylinder and a rotatable crankshaft coupled to the piston to be rotatably driven as combustions within said cylinder occur at said ignition instants. The crankshaft has a reference position defining a positional relationship of the crankshaft to the cylinder. The ignition system includes an optical encoder directly coupled to the crankshaft for generating ignition signals upon the termination of a variable crankshaft arc beginning at a point fixed with respect to the reference position. The length of the crankshaft arc is set as a function of one or more selected engine parameters.
