Abstract
A tubular exhaust gas manifold for an automotive internal combustion engine comprises pipes with flanges for bolting to the side of the engine to separately receive exhaust gas from individual cylinders, the other ends of the pipes being bunched together and welded to a collector that provides a common mixing and outlet chamber for the gases and has a flange for connection to an exhaust pipe. An air feed means is mounted on the pipes and it takes the form of an air log supported on the pipes by means of the air runner tubes that deliver air separately to the individual pipes.
