Abstract

An exhaust gas line system for an internal combustion engine supercharged by an exhaust gas turbocharger, having a modularly assembled exhaust gas collector pipe (1), which supplies the turbocharger with exhaust gas and is connected to all cylinders of a bank of cylinders via connecting lines (2), the exhaust gas collector pipe (1) being closed at its end distant from the turbine and exhibiting, over its entire length, a nearly constant cross section. It is the object of the invention to create, for a supercharged internal combustion engine, an exhaust gas line system that utilizes the kinetic energy of the exhaust gas in the most loss-free possible fashion for driving the turbocharger. This is achieved by the connecting lines (2) discharging into the exhaust gas collector pipe (1) via a diffusor-shaped inlet opening (3) and by providing a constriction (4) upstream of the inlet opening.
