Abstract

In an internal combustion engine with an exhaust turbocharger, a bypass line is provided between the intake pipe connected to the charger and situated downstream of the throttle valve and the exhaust pipe opening into the turbine. Arranged in the bypass line is a valve which shuts off the bypass line only when the exhaust gas pressure in the exhaust pipe exceeds the charging pressure in the intake pipe by a certain amount and a connection is having a disadvantageous effect on the performance of the internal combustion engine. Below this pressure range, the valve is open and the connection between the intake pipe and the exhaust pipe is free. In the operating condition of the internal combustion engine in which the charging pressure is higher than the exhaust gas pressure, it is thereby possible for fresh gas from the intake pipe to pass into the exhaust pipe and for automatic supplying of secondary air to take place. If, on the other hand, the exhaust gas pressure is higher than the charging pressure, exhaust gas flows across from the exhaust pipe into the intake pipe, automatic exhaust gas recirculation thus taking place.
