INTAKE APPARATUS FOR AN INTERNAL COMBUSTION ENGINE |
摘要 |
The invention is directed to an intake apparatus for an internal combustion engine with the apparatus including an intake pipe defining a longitudinal axis and a throttle flap mounted on the intake pipe, the throttle flap including a shaft having a shaft radius (r), a throttle flap having a thickness (t) and being mounted on the shaft to be rotatable through a displacement angle, and the shaft having a diameter (2r) greater than the thickness (t); a potentiometer operatively connected to the throttle flap for detecting the displacement angle thereof; a full-load stop for fixing the displacement angle of the flap at full load; the throttle flap being adjusted to a stop angle AW of the throttle flap by impacting on the full-load stop pursuant to the relationship: (2) (KETW)+(2) (AETW) SIMILAR (2) (WSW)-DAW wherein: WSW is a shaft shading angle, the angle of the throttle flap at which points on the throttle flap disposed farthest away from the shaft lie at a distance from the longitudinal axis equal to the radius (r); KETW is a permissible corresponding tolerance angle corresponding to the tolerance of the potentiometer; AETW is a permissible tolerance angle for the stop of the throttle flap; and, DAW is the difference angle by which a rearward tolerance limit for the throttle flap stop lies ahead of a rearward shaft shading limit. Because of the increased tolerance, adjusting devices can be omitted or adjusting measures such as preparatory procedures can be avoided.
