Abstract

PURPOSE:To enable to reduce the passage sectional area of a primary suction air passage and increase an eddy current generating effect in a combustion chamber by a constitution wherein the exhaust reflux gas is induced into a cylinder under the suction stroke thereof only through a secondary suction air passage by so-called secondary side leak phenomenon. CONSTITUTION:In the internal-combustion engine, of which carburetter is consisting of a primary carburetter 2 for light load and a secondary carburetter 4 for heavy load, a reflux port 28 is opened at a down-stream position of a secondary choke valve 12 for a secondary suction air passage 8 for the heavy load and this reflux port 28 is communicated with the introducing port 22 of an exhaust passage 20 through an EGR control valve 26. A BPT (an exhaust pressure transducer) 30 is communicated with the EGR control valve 26 and it is constituted so that a primary negative pressure is introduced from a sensing port 32 provided at the part of a primary choke valve 10. According to this constitution, the reflux gas from the exhaust passage 20 is counter-flowed to the direction of the cylinder under the suction stroke thereof and is induced into respective cylinders from the secondary suction air passage 8 by so-called secondary side leak phenomenon.
