FIELD: internal combustion engines.
SUBSTANCE: disclosed are methods and systems for blowing coal filter for fuel vapours. In one example, when the supercharged engine is in operation, the method may include controlled use of compressed air from the engine inlet port for blowing fuel vapours accumulated in the coal filter. Further, in the absence of supercharging for blowing of the carbon filter, air from the inlet channel can be controlled. Swirled fuel vapours and sucked-in air can be fed into zone upstream of compressor at operation with supercharging or into intake manifold at operation without supercharging.
EFFECT: invention can be used in the internal combustion engines.
