Method for recirculating part of exhaust gases from exhaust pipe of diesel engine to its inlet has at least one of dampers always maintained open and that other damper closed using drive motor common to dampers

摘要

A controlled valve is located between an engine and its air intake. The valve includes dampers (20,21) arranged in inlet channels (17,18) for the recirculated exhaust gases and air respectively. At least one of the dampers (20,21) always is maintained open and that the other damper (20,21) is closed by a drive motor (22) common to the dampers. Independent claims are included for: (a) a device for recirculating a part of the exhaust gases from an exhaust pipe of a diesel engine (b) a method for regulating of a diesel engine (c) a regulating device for a diesel engine
