Claims11
A distributor for internal combustion engines comprising a shaft rotating synchronously with a crankshaft of an engine, a signal rotor rotatable with said shaft, a rotation signal detector for detecting a rotating angle of said crankshaft from rotation of said signal rotor, and an ignition coil for applying a high voltage to an ignition plug of each of cylinders, wherein:
- said distributor for internal combustion engines further comprises a first connector for electrically coupling an engine control unit outside said distributor and said rotation signal detector;
- and
- a second connector for electrically coupling said engine control unit and said ignition coil, wherein said second connector comprises a terminal for supplying current from a battery to a high voltage side of a primary winding of the ignition coil;
- said first connector and said second connector being each structurally integral with said rotation signal detector.
A distributor for internal combustion engines comprising:
- a rotary shaft rotating synchronously with a crank shaft of an engine;
- a signal rotor rotatable with said rotary shaft;
- a rotation signal detector for detecting a rotating angle of said crank shaft from rotation of said signal rotor;
- and
- an ignition coil for applying a high voltage to an ignition plug of each of cylinders, wherein:
