It slows down the response of the vacuum valve that controls charcoal
canister flushing, so that it doesn't instantly open when the
throttle plate comes off the idle stop.  And likewise slows down the
valve closing when the throttle is closed.  Is it to avoid a problem
with bogging down from idle?  That or emissions are the only reasons
I can think of.  Is it German aesthetics or a significant thing?  I dunno.
