Function Description
A pneumatically actuated resonance flap (5) is located
on the intake manifold, and will be opened and closed by
load, which operates resonance flap according to engine
and controlled by ECU and rpm.
1. Resonance flap closed (at idle/partial load : less
than 3,800/rpm)
The switch valve (7) will be adjusted by ECU and res-
onance flapwill be closed. By increasing air flow pas-
sage through dividing intaking air flow toward both air
collection housing (8). This leads to a signficant in-
crease in the torque in the lower speed range.
2. Resonance flap open (at full load:over 3,800/rpm)
The switch valve (7) will not be adjusted by ECU and
resonance flap (5) will beopen. The colllected air in
the air collection housing (8)will not be divided and
intaking air passage will be shorten.
