CARBURETION DEVICES FOR INTERNAL COMBUSTION ENGINE

摘要

The device has a main jet for normal operation and an idling circuit, both opening into the intake pipe and provided with calibrated orifices to adjust the richness of the air/fuel mixture. An adjustable throttle enables the idling mixture to be adjusted. The adjustable throttle can be bypassed through a passage to the mixing channel during deceleration. The passage has a closing member actuated by a capsule governed by the suction in the intake and by a member sensitive to the engine's speed. When the bypass is closed the capsule is connected to atmospheric pressure. The capsule is fixed to an element compensating for altitude.
