FIELD: engines and pumps.
SUBSTANCE: group of inventions relates to a split exhaust in an exhaust system of a boosted internal combustion engine. Methods and system for a supercharging engine having a divided exhaust system are described. One method includes reducing detonation by delivering a mixture consisting of purge air and exhaust gases discharged from the cylinder towards the end of the exhaust stroke. This mixture is fed to the compressor inlet through the compressor inlet valve.
EFFECT: technical result is increase in the engine reliability.
