Abstract

PURPOSE: To reduce a discharge amount of harmful exhaust from an engine in a tunnel or the like, by providing a three-way valve in the downstream side of a circulating passage from a pressure regulating valve and selecting operations of the engine optionally from that in the atmosphere to that by regenerative cycle.
CONSTITUTION: There are provided an exhaust valve 11, emitting exhaust gas by communicating an exhaust gas circulating passage 3 to a side of the atmosphere, and an intake valve 12, located immediately before a feed air port 1b and sucking the atmospheric air by communicating the exhaust gas circulating passage 3 to a side of the atmosphere, in the downstream side of the circulating passage 3 from a pressure regulative valve 6. Said intake valve 12 is constituted by a three-way valve closing a section of the exhaust gas circulating passag 3 between the exhaust valve 11 and the intake valve when the intake valve is opened for intake operation. Accordingly, operation of an engine in the atmosphere is performed by closing an oxygen flow rate control valve 5 and opening the exhaust valve 11 and the intake valve 12, while operation of the engine by regenerative cycle is performed by opening the oxygen flow rate control valve 5 and opening the exhaust valve 11 and the intake valve 12.
