BI-TURBOCHARGER INTERNAL COMBUSTION ENGINE WITH EXHAUST GAS RECYCLING

摘要

The invention relates to an internal combustion engine comprising several cylinders arranged in two rows and two turbochargers driven each by the exhaust gases from the cylinders of one cylinder row. The inventive engine is provided with a system for recycling the exhaust gases, which comprises two conduits designed for guiding the exhaust gases and used to separate the fraction to be recycled of exhaust gases from the cylinders of one cylinder row, upstream from the respective turbocharger, and to convey said fractions to a common recycling conduit for conveying the gases to be recycled to an air supply, downstream from the turbochargers. The exhaust gas recycling valve comprises plugging members which are used to adjust the amount of exhaust gases to be recycled. Said plugging members comprise blocking means which can suppress the communication between the two exhaust gas recycling conduits.
