The drawing illustrates a sheet metal air filter housing 10 of generally cylindrical shape, a cylindrical ,~ annular air filter 12 contained within housing 10, a plastic circuit board mounting housing 14 and a moulded plastic ; ~ -intake snorkel 16. Hollsing 10 and filter 12 are generally '1 . , of conventional construction and mount on the engine in the ~J usual fashion; however, in accordance with principles of the present invention certain modiications may be made to the housing 10 which include ~he provision of one or more openings 18 formed in the side wall of the housing, a plurality of attaching brackets 20 for attachment of circuit board housing 14, and the height of the side wall of the hou~lng 10 may be somewhat increased. The cover for housing ¦ 10 has not been shown in the drawing in the interest of clarity.

Hous1ng 14 is of generally concave shape extending circumferentjally of housing 10 and disposed over the openings 18. Housing 14 attaches to hous1ng lO by means of attachment screws 22 which are threaded into brackets 20. An annular seal-ing gasket 24 seals between the two housings and is compressed to a limited extent when the screws 22 are tightened to draw the lO housing 14 against housing lO. A leak-proof seal is attained by providing a plurality of individual protuberances such as 26 at locations around the inner edges of ~he upper and lower walls of housing 14. With this arrangement, when the screws 22 are . tightened the gasket 24 will be controllably compressed with the 15 compression thereof being limited by the protuberances 26 abutting ~! the wall of the air filter housing lO, A continuous backup flange 28 is provided for gasket 24. The radially outer edge of housing 14 terminates in an opening over which snorkel 16 is disposed. Snorkel 16 is a tubular element and its inner peripher ;
20 is provided with a flange wh;ch abuts the radially outer peripher of housing 14 and the two elements 14 and 16 are secured together by any suitable securing means. Desirably, a sealing gasket 30 rnay be provided between the two. When the engine ;s operated induction air is drawn through snorkel 16 and housing 14, through 25 openings 18 and through air ~ilter 12 into the engine carburetor to be mixed with ~uel for combustion in the engine.
The inveiltion provides within housing 14 the mounting of electronic circuitry which is associated with a control system for the engine, for example electronic fuel metering controls, 30 electronic spark t;ming controls, or electronic fuel injection controls. The circuitry in the illustrated embodiment is con-tained in a number of individual electronic circuit modules 32 of the plug-in type which plug into electronic circuit boards 34 , ~_ _ . ~ 3~-~3 ~
Iwhich are removably secured within houslng 14. The two circuit .~ Iboards 34 are removably mounted on housing 14 by means of attach-¦;ng screws 36 which pass throuyh open;ngs in the boards to engage ¦threadedly threaded holes in molded structural ribs 38'which are . l integrally formed in housing 14. The modules 32 removably mount on boards 34 by means of plug-in type terminals. The modules may contain individual electronic circuit boards 38 having in-dividual circuit components thereon, the boards 38 being potted by means of suitable potting material within sheet metal receptacl s 40. Lead wires from the circuit boards 34 terminate in connec~or . plugs 42 which mount in the bottom wall of housing 14. Plugs 42. 15 are mateable with matching connector plugs (not shown) to effect connection of the circuits on the boards with additional portions . of the system which are located exteriorly of housing 14. Inter-nal connections between the individual modules and circuit boards . can be accomplished by in~ernal connections. The loca~ion of modules 32 within housing 14 is such that adequate clearance is provided to permit induction air to pass freely into the engine . . without apprec;able obstruction while a~ the same time exposingthe c;rcuit components to the conduct;ve cooling afforded. by the ;nduct;on air. Thus, even in the hok environment of an under-~ 25 hood eng;ne compartment, the electronic circuit components can be : ma;nta;ned ;n a thermal env;ronment which is no~ detrimental tothe cTrcuit components. A further system component 44 ;s shown d;sposed on snorkel 16 and extending through an opening in the snorkel to be disposed ;n the path of travel o~ the induction air.
Th;s element could be any of a number of possible devices and ;s illustratlvely shown as a probe for monitor;ng the velocity of . ;ntake air flow through snorkel 16. An electronic circu;t module 46 is contained in assoc;ation with element 44 w;th;n a cover 48 wh;ch mounts on snorkel 16~
