ABSTRACT:
The fuel feed device comprises a butterfly valve actuated by the driver and an auxiliary throttle member which opens automatically in proportion to the rate of air-flow in the intake passage of the engine. The pressure of the fuel which is delivered into the intake at a location downstream of the butterfly by an injector is adjusted by an unloading valve. The fuel pressure tends to open the unloading valve and the under-pressure which prevails in a control chamber tends to close it. The control chamber has a connection with a portion of the intake which is located downstream of the auxiliary throttle member. That connection is open when the under-pressure is moderate. The connection has also a branch connected to an additional air channel for cold running of the engine which is open when the temperature of the engine is lower than a predetermined value.
