Abstract
The invention relates to a supercharged internal combustion engine having at least two cylinder groups of at least one cylinder each, both cylinder groups being equipped with an exhaust pipe, and the two exhaust pipes being in communication with one another, and having two exhaust gas turbochargers, the turbines of which are connected in parallel, with their compressors connected in series, and having an exhaust gas recirculation line which upstream of one of the two turbines branches off from the exhaust pipe assigned to this turbine and opens out into the common intake line. An advantage of this invention is that it provides a supercharged internal combustion engine which overcomes the drawbacks which are known from the prior art and can be used to realize high exhaust gas recirculation rates and high boost pressures, in particular simultaneously, in all the load ranges of the internal combustion engine.
