Abstract
The proposal is for a suction pipe consisting of a number of individual suction pipes (10, 16, 17, 18) connected on the intake side to a manifold (11). According to the invention, the manifold is made in one piece with the suction pipes by the blow-molding method.
Claims15
An intake manifold for an internal combustion engine comprising a plurality of intake pipes, a connecting manifold which connects the intake pipes, and a shunt resonator in communication with the manifold;
- wherein the intake pipes, the connecting manifold and the shunt resonator are formed by blow-molding as a single, unitary piece.
An intake manifold for an internal combustion engine comprising a plurality of intake pipes and a connecting manifold which connects the intake pipes;
- wherein the intake pipes and the connecting manifold are formed by blow-molding as a single unitary piece, and each intake pipe has an associated connecting flange arranged at amend thereof proximate said engine, and each intake pipe is connected to the associated connecting flange by means of a plug-type connection.
An intake manifold for an internal combustion engine comprising a plurality of intake pipes and a connecting manifold which connects adjacent ends of the intake pipes;
- wherein the intake pipes and the connecting manifold are formed by blow-molding as a single unitary piece, and the connecting manifold is formed with an opening in one side opposite the adjacent ends of the connected intake pipes.
A method of producing an intake manifold for an internal combustion engine comprising a plurality of intake pipes and a connecting manifold which connects the intake pipes, said method comprising blow-molding the intake pipes and connecting manifold from synthetic resin as a single, unitary piece.
