INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To stabilize the compression self-ignition combustion by utilizing the reformed evaporation fuel. SOLUTION: This internal combustion engine has a canister 28 for temporarily holding the evaporation fuel from a fuel tank 18 and a mixing chamber (reforming means) 30 for mixing the evaporation fuel purged from the canister 28 with the EGR gas so as to reform the fuel to the property suitable for the compression self-ignition combustion. In the case where a control unit (determining means) 26 determines to perform the compression self-ignition combustion, the reformed evaporation fuel is injected for supply to a combustion chamber 12 of the engine through a second branch purger passage 38.
