FIELD: machine building; engine building.
SUBSTANCE: invention can be used in the internal combustion engines. Disclosed is a method for a supercharged engine. Electronic controller (12) controls the opening of common shutoff valve (CSV) (24) on the basis of conditions of engine (10) operation in idle mode with maintenance of engine operating conditions in idle mode. Also, the CSV opening degree is controlled based on each flow of the ejection flow through aspirator (22) and the crankcase ventilation flow. Crankcase ventilation flow comes from crankcase (144). Ejecting flow and crankcase ventilation flow are mixed with each other in unit (98) between aspirator and inlet header (44) and pass through CSV when CSV is open. Disclosed are an engine system and a supercharged engine method.
EFFECT: technical result consists in improvement of fuel efficiency.
