Abstract
PURPOSE: To ensure reliable ignition of air-fuel mixture in each combustion chamber by an ignition plug and thus suppress generation of NOx without adversely affecting the engine operation performance with such a construction that the re-circulated exhaust gas is distributed over the lagging side of each combusion chamber.
CONSTITUTION: In a rotary engine, which has first and second cylinders 23 and 24, and in which the phase of the rotor 3 in the first cylinder 23 and that of the rotor 3 in the second cylinder 24 differ from each other by 180° in terms of the angle of the common output shaft 14, a first EGR duct 31 connecting a first exhaust duct 27 connected to an exhaust port 6 of the first cylinder 23 to a second intake duct 26 connected to an intake port 5 of the second cylinder 24 and a second EGR duct 32 connecting a second exhaust duct 28 connected to an exhaust port 6 of the second cylinder 24 to a first intake duct 25 connected to an intake port 5 of the first cylinder 23 are provided, and on-off valves 33 and 34 are mounted on the respective EGR ducts 31 and 32
