DEVICE FOR ENRICHING THE FUEL MIXTURE IN THE INTERNAL COMBUSTIN ENGINE

摘要

A vacuum capsule opens an additional fuel circuit when the vacuum in the suction manifold has a comparatively low value because the engine functions at heavy duty conditions and full power; said circuit has two branch conduits to feed fuel both to the main feed circuit and the idling circuit of the carburettor. The amount of fuel supplied to these two circuits is adapted to maintain the correct strength of the mixture supplied by the carburettor in the running conditions for which the vacuum capsule opens said circuit.
