Abstract
PURPOSE: To prevent the production of sulfuric acid and the deposition of carbon, by increasing the exhaust gas recycle ratio of an exhaust gas recycle purifier for a compression-ignited internal combustion engine having auxiliary chambers when the engine is idling or under a low load.
CONSTITUTION: Each of the plural cylinders #1W4 of the compression-ignited internal combustion engine has an auxiliary chamber 7 connected to a main combustion chamber through a hole 6. A fuel injection nozzle 8 is opened into the auxiliary chamber 7. The auxiliary chambers of the cylinders are connected to one another through exhaust gas return passages 12, stop valves 13 and exhaust gas expansion pipes 11. A bypass 20 is provided in an intake passage 9. The quantity of new intake, which is conducted through the bypass, is controlled by a negative pressure control valve 23 which is driven through a diaphragm 25a by negative presure picked up through a negative pressure pipe 27 opened at the downstream side of a control valve 19. Said stop valve 13 is opened in response to an increase in the load upon the engine.
