Signal generator for an internal combustion engine

Abstract

A signal generator for an internal combustion engine containing (1) a housing and (2) a shaft penetrating the housing, at least one asymmetrical vane type rotor coupled to the shaft, one signal element mounting plate, at least one signal element, and a stray noise isolating plate provided in the housing. The shaft is coupled with the engine to drive the asymmetrical vane type rotor to rotate synchronously with the engine and move pass the signal element so as to generate a square wave signal for controlling a fuel injection and ignition of the engine. The signal element mounting plate is mounted on the housing via an outer edge of the mounting plate, which is used as a fulcrum and to cause the signal element mounting plate to be fastened to the housing in such a manner so as to allow a large space to be provided by its top and bottom surfaces for mounting a increased number of the signal elements thereon. The stray noise isolating plate is mounted above the vane type rotor and the signal elements so as to form a closed space of the housing. The stray noise isolating plate provides the functions of shielding high voltage stray noises from being received by a microcomputer, which monitors the signal from the internal combustion engine, and preventing the ozone produced by sparks generated by the engine to enter the housing which could cause rusting.
