FIELD: machine building.
SUBSTANCE: methods and systems have been proposed for improving control over the ratio of the amount of air to the amount of fuel purge. Fuel vapour and gases from the fuel vapour reservoir and the engine crankcase are selectively blown into certain selected groups of cylinders or one cylinder of the engine and not blown into the remaining engine cylinders. Then the exhaust gases are fed into the engine inlet through the system of exhaust gas recirculation (EGR) from a selected group of cylinders or one cylinder, from where the specified recirculated exhaust gases are sucked into the remaining engine cylinders and into the selected group of cylinders. Invention allows to achieve improved combustion in the cylinders and improved engine performance.
EFFECT: invention can be used in fuel supply systems of internal combustion engines (ICE).
