<p>PROBLEM TO BE SOLVED: To eliminate evaporated fuel gas adsorbed in adsorbent in a charcoal canister without using the other power in a cylinder direct fuel injection type internal combustion engine. SOLUTION: A part of suctioned air pressurized by a supercharger 14 flows through a bypass passage 20 including a canister 17. At this time, bypass valves 21 and 22 are opened and a solenoid valve 19 is closed. As for a difference in pressure for flowing the suctioned air, it may be taken out from the front and rear of a throttle valve 13 in an intake pipe 5 or may be generated by providing an exhaust throttle valve in an exhaust pipe 10, rotating a turbine due to a difference in pressure in the front and rear of the exhaust throttle valve, and using a compressor driven by it. Moreover, an injection amount of a fuel injection valve 6 is adjusted in accordance with an amount of the eliminated and evaporated fuel gas.</p> |
