ABSTRACT:
A housing containing a pair of electronic circuit boards removably mounts on the side of an engine air filter housing. The circuit board housing has a generally concave inner face matching the convex contour of the air filter housing side wall and is disposed over air circulation openings in the air filter housing side wall. In a first embodiment, the circuit board housing is of one-piece construction and the electronic circuit boards are disposed interiorly of the outer wall of the circuit board housing and in generally parallel relationship therewith. In a second embodiment, the circuit board housing is of two-piece construction having upper and lower halves. In this embodiment, the circuit boards are horizontally disposed, one each in each of the two housing halves. Connectors for effecting connection of the circuit boards with the other components of the system which are located exteriorly of the air cleaner housing extend through holes in the circuit board housing. The circuit boards contain electronic control circuitry for the engine, for example, an electronic engine spark timing control system. Other devices such as transducers may also mount on the circuit board housing.
