Abstract
Apparatus for the continuous injection of fuel into the intake piping of an internal combustion engine comprises an air pump for delivering an air stream portion deviated from the engine intake pipe, a fuel pump for delivering fuel from a source, a metering device controlled in response to operating conditions of the internal combustion engine and receiving fuel delivered by said fuel pump and the air stream portion delivered by said air pump for mixing said fuel and air stream portion and delivering the same to the intake piping of the engine, in which the supply of said air stream portion to the metering device is interrupted during an operating condition of the engine, preferably a coasting condition of operation of the engine. Interruption of the air stream portion may be effected by a shut-off valve in the conduit delivering the air stream portion from the air pump, responsive to a coasting condition of the engie. Alternatively, this may be accomplished by disabling the air pump during a coasting operation of the engine and enabling the air pump at the end of such operation.
