PURPOSE:To supply not only purge gas but also gas to be sucked into an engine, in addition to intake air, into respective cylinders by the desired amounts, by supplying purge gas, EGR gas and auxiliary air into intake pipes of respective cylinders. CONSTITUTION:Intake air disperses into respective cylinders after being sucked through a throttle valve 34, and it is sucked into an engine main body 37 and burnt. Combustion gas is discharged as exhaust gas to an exhaust pipe 38. Valves 36 for promoting good combustion are provided on intake pipes of respective cylinders. Fuel to be evaporated from a fuel tank 30 is adsorbed by an absorber 31, separated by air, and sucked into the engine. The amount of intake gas is controlled by a valve 32. Moreover, exhaust gas is guided into the intake pipes by a passage 39 in order to reduce nitrogen oxide, and the amount is controlled by a valve 35. An opening part of a supplying passage 40 for gas is provided in the intake pipe positions of respective cylinders where the distribution becomes most suitable, so as to also serve as a supplying passage for gas from the absorber and EGR gas. |
