Abstract

PURPOSE: To ensure the returning of exhaust gas and prevent an interception valve against dirt by connecting and opening an exhaust-gas returning passage to a suction passage on the operation side and on the other hand introducing exhaust gas into a suction passage on the intermission side from an exhaust passage on the intermission side via an exhaust-gas circulating passage for the operation of all cylinders.
CONSTITUTION: In a cylinder-number-controlled engine which stops operations of cylinders partly for a light load, an exhaust-gas returning passage 14 is connected and opened to an operation-side suction passage 6 in the downstream of a branch point A. Meanwhile, an exhaust-gas returning valve 13 and an exhaust-gas circulating valve 12 respectively provided on ways of an exhaust-gas circulating passage 11 and an exhaust-gas returning passage 14 are connected via a three-way electromagnetic valve 15, by which the negative pressure of an exhaust-gas returning control signal to the exhaust-gas returning valve 13 is supplied to the exhaust-gas circulating valve 12. This construction permits to return exhaust gas for sure in any operation of all cylinders or partial cylinders, and simultaneously prevent at interception valve 10 against dirt.
