ABSTRACT:
A spark ignition distributor assembly having air density compensating means is provided for use with an internal combustion engine. A first distributor plate is rotatably mounted between a first and second position within a housing while a second distributor plate in turn is rotatably mounted between a first and second position on and coaxial with the first distributor plate. A distributor shaft is rotatably journalled in the housing and extends coaxially through both distributor plates. An actuator connected to the shaft selectively actuates a make-and-break switch mounted on the second plate. The rotational position of one of the plates is controlled by the manifold vacuum of the engine while the rotational position of the other plate is controlled substantially by the density of the incoming air to the engine via appropriate sensing devices.
