ABSTRACT:
An exhaust manifold for an engine having at least one combustion chamber and multiple exhaust valves arranged on a first plane is provided with a housing formed to provide a longitudinally extending main exhaust gas passage on a second plane terminating in an outlet at one end. A plurality of discrete, laterally spaced, inlet branch passages include a floor and a ceiling which are initially level with the exhaust valve for a distance equal to one-half the width of the inlet branch passage prior to sloping downward toward the main exhaust gas passage. One of the inlet branch passages is positioned at an end of the housing opposite the exhaust gas passage outlet. The remaining inlet branch passages include integrally formed deflector members arranged to provide an angular change of flow direction requiring exhaust gas to enter the main exhaust gas passage in the downstream direction.
