A combined electronic ignition and fuel injection system for internal combustion engines utilizes a non-magnetic disk, attached to the engines shaft and rotates with the shaft, and contains permanent magnet along the periphery of the disk at intervals defined by the shaft's position for each cylinder group. The magnets develop voltage timing pulses within pick-ups coils which are connected to circuits for amplifying and shaping the timing signals. The coil driver switch charges the ignition coil and the spark plugs are then fired, then in another cylinder chamber the fuel injectors are opened, and the fuel is injected into the cylinder chamber. This electronic ignition and fuel injection system is an improvement and a simpler system than that which is usually utilized in internal combustion engines, because it does not require the use of a computer or distributor. It is particularly useful in the rotary-reciprocal combustion engines, and may be used in rotary and reciprocal combustion engines.
