Abstract (en)
[origin: EP1063406A1] A throttle plate (16) is pivotable in the cross-section (17) of a pipe system. When in its closed position, the throttle plate leaves open a residual cross-section through which fluid to be throttled can flow. The throttle plate may be arranged in the narrowest section of a pipe section with a veturi-shaped cross-sectional profile, esp. an inlet manifold. The throttle plate may be arranged in the inlet region of the intake manifold. The residual cross-section may be ring-shaped and between 10 and 40 per cent of the total area of the cross-section. An Independent claim is included for a method of controlling a throttle in an internal combustion engine.
