Abstract
A suction pipe apparatus for an internal-combustion engine with fuel injection, especially intermittent fuel injection into intake pipes connected to the cylinder head of the engine. The intake pipes are connected to the cylinder head by a flanged, structure-borne-noise-insulating connecting pipe made from an elastomer. A sleeve-shaped portion for receiving a fuel injection valve is also provided at the connecting pipe. The sleeve-like portion encapsulates the valve to reduce noise emissions. The flange of the connecting pipe is provided with a reinforcing member to enhance the integrity and durability of the connection.
