    Abstract: PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine capable of precisely controlling an air-fuel ratio for each cylinder independently of an opening/closing state of a WGV (waste gate valve) in a multi-cylinder internal combustion engine with a supercharger having the WGV.SOLUTION: It is determined whether or not a WGV 40 is opened (steps 100 to 102). As a result, when the WGV 40 is closed, a transport lag time used in controlling an air-fuel ratio is set to a value corresponding to an exhaust path length passing through a turbine 301 (step 104). When the WGV 40 is opened, the transport lag time used in controlling the air-fuel ratio is set to a value corresponding to an exhaust path length passing through an exhaust bypass passage 38 (step 106). The cylinder corresponding to an output signal of an air-fuel ratio sensor 52 is identified on the basis of the set transport lag time, and air-fuel ratio control for feeding back the output signal of the air-fuel ratio sensor 52 to calculation of a fuel injection amount of the identified cylinder is executed (step 108).

    Abstract: PROBLEM TO BE SOLVED: To speedily supply evaporated fuel into a cylinder even at a low-temperature start for improving the starting performance in a control device of an internal combustion engine.SOLUTION: An engine 10 includes a normal fuel tank 32, an evaporated fuel tank 36, a tank ejection valve 38 and an evaporated fuel supply valve 40 or the like. At starting, an ECU 60 supplies, to a surge tank 20, the evaporated fuel stored in the evaporated fuel tank 36 during the operation of the engine. When the evaporated fuel runs short at the starting, fuel is ejected into the evaporated fuel tank 36 from the tank ejection valve 38 while the normal fuel ejection is prohibited, and the evaporated fuel supply valve 40 and an atmospheric air introduction valve 42 are opened simultaneously with the fuel ejection. Thereby, the evaporated fuel can be quickly supplied into the cylinder, not only when a sufficient amount of the evaporated fuel is stored at the starting but even when the evaporated fuel runs short.

    Abstract: PROBLEM TO BE SOLVED: To promptly supply vaporized fuel into a cylinder even at low temperature start, and to improve starting performance.SOLUTION: An engine 10 includes a normal fuel tank 32, a vaporized fuel tank 36, an in-tank injection valve 38, a vaporized fuel supply valve 40, an in-tank ignition plug 44 or the like. An ECU 60 supplies the vaporized fuel to a surge tank 20 at the start-up while accumulating the vaporized fuel during the drive of the engine in the vaporized fuel tank 36 in advance. Furthermore, when the vaporized fuel is insufficient at the start-up, the ECU first burns the vaporized fuel remaining in the vaporized fuel tank 36 by using the in-tank ignition plug 44, and then injects the fuel into the vaporized fuel tank 36 which is heated by combustion from the in-tank injection valve 38. By this arrangement, even if inevitably generating the vaporized fuel at the start-up, the vaporized fuel can efficiently be generated in a short time, and the generated vaporized fuel can promptly be supplied into the cylinder.

An air phase chamber 36B and a liquid phase chamber 36C are formed in the vaporized fuel tank 36. An ECU 70 supplies the vaporized fuel to a surge tank 20 at the start-up while accumulating the vaporized fuel generated during the drive of the engine in the air phase chamber 36B in advance. By this arrangement, the starting performance can be improved. Furthermore, the fuel is injected from the in-tank injection valve 38 on assumption that liquid phase fuel may remain in the liquid phase chamber 36C at the generation of the vaporized fuel, and the vaporized fuel can be generated even at cold staring. Furthermore, the vaporized fuel generated in the liquid phase chamber 36C during the drive is replenished to the air phase chamber 36B, and a large volume of the vaporized fuel can be accumulated in the air phase chamber 36B as much as possible.

    Abstract: PROBLEM TO BE SOLVED: To improve startability by supplying vaporized fuel into a cylinder even at a low temperature start.SOLUTION: An engine 10 includes a normal fuel tank 32, a vaporized fuel tank 36, an in-combustion chamber injection valve 44, a vaporized fuel supply valve 46, or the like. A fuel chamber 40 and an air chamber 42 are demarcated by a free-piston 38 in the vaporized fuel tank 36. An ECU 70 supplies the vaporized fuel stored in the fuel chamber 40 during an operation of the engine to an intake path 12 upon starting. The vaporized fuel is thereby quickly supplied into the cylinder even at a low temperature start. Further, the vaporized fuel is stored in the fuel chamber 40 while being separated from the air, and the air introduced into the tank in accordance with the remaining amount of the vaporized fuel may be accommodated in the air chamber 42. Accordingly, a vapor concentration of the vaporized fuel is stabilized because air is not mixed therein upon generation of the vaporized fuel or during storage.
