Abstract
A distributor for an internal combustion engine which changes the ignition timing of the engine based on two variables including the rotating speed of the engine and the load imparted to the engine. A sleeve is loosely mounted on a rotary shaft of the distributor, and an ignition changing timing cam is loosely fitted on the sleeve to be rotatable around the axis of the shaft with the sleeve and movable in the axial direction of the shaft relative to the sleeve. A pair of centrifuzed weights urges the cam in the axial direction in response to the speed of the engine. A first link mechanism has at one end a follower of the cam and at the other end is connected to a breaker plate for the distributor contacts to rotate the plate and thereby change the ignition timing in response to engine speed. A second link mechanism is connected at one end to the sleeve and at the other end to a diaphragm actuator which responds to the load on the engine. The second link mechanism thereby rotates the sleeve and cam to change the ignition timing in response to engine load.
