Abstract

An intake system for a combustion engine has at least two rows of cylinder heads, each of which features an intake manifold with individual pipes leading to the cylinders. The intake manifolds are connected to one another through transverse ducts equipped with switching valves as well as to an air supply duct leading to one of the transverse ducts, which features a throttle valve to regulate the air volume. The air supply duct is preferably comprised of a double-fluted distributor pipe leading to one of the transverse ducts. A throttle valve housing is connected upstream of the distributor pipe, and an interior wall is integrated into the distributor pipe, thereby dividing the interior space thereof into two interior ducts of virtually equal cross section.
