Patent number: 3949717Abstract: The air pressure in the intake valve undergoes a sudden decrease upon closure of the throttle valve. This decrease is sensed and opens a bypass which furnishes some air to the air intake means when the throttle is fully closed. The quantity of air so furnished is sufficient to allow combustion in all cylinders of the engine, thereby preventing excessive cooling.Type: GrantFiled: October 11, 1972Date of Patent: April 13, 1976Assignee: Robert Bosch G.m.b.H.Inventors: Norbert Rittmannsberger, Hermann Hoelle, Klaus Bertsch
