ABSTRACT:
A compact combination engine air cleaner
oise deadener for installation in the engine compartment of a motor vehicle type engine includes a two piece plastic elongated housing that is compact and has an ambient air inlet at one end radially spaced from an air outlet to the engine located on the axis of the housing, the inlet containing a first noise attenuating venturi, the housing having an air filter at the other end connected to the venturi and discharging air into a second convergent-divergent flow control noise attenuating venturi with which is integrated a mass air flow sensor, the venturis being surrounded by a dead air space type resonating chamber that has an inlet concentric with the air outlet so that engine feedback noises and sound waves are trapped in the chamber and dissipated, and any sound waves passing serially into the venturis bounce off the walls of the venturi diffusers to also be dissipated, thus minimizing the transmission of engine feedback noises past the air cleaner.
