Exhaust gas ducting system in a multi-cylinder internal combustion engine supercharged on the dynamic head principle

摘要

In the case of an exhaust gas ducting system in a multiple cylinder internal combustion engine supercharged on the dynamic head principle an exhaust gas manifold is connected to the turbine of an exhaust gas turbocharger, into which manifold connecting pipes leading away from the cylinder head side exhaust gas outlets of the engine open. That area at which a connecting pipe opens into the exhaust gas manifold is designed as a short diffuser. In addition a baffle plate having approximately the form of a cone and designed to promote the flow is arranged in the mouth area of each connecting pipe as part of such a short diffuser, the cone of the plate partially projecting into the mouth area of the associated connecting pipe.
