ABSTRACT:
A contactless ignition system for use with an internal combustion engine has at least one pulser adapted to detect predetermined maximum and minimum advance angular positions of ignition timing. A first triangular wave form having a first rising gradient and a second triangular wave form having a second rising gradient are formed based on the output of the pulser. When a voltage representative of sum of the first triangular wave form and a reference voltage of a fixed level and the second triangular wave form coincide with each other, an advanced ignition signal of ignition timing is produced, whereby substantially constant advance angles are maintained within low speed range and high speed range of the engine and an advance angle at intermediate speeds of the engine is so controlled as to be proportional to the number of rotations of the engine.
