    Abstract: PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine, which can suppress variation in an intake air amount between cylinders while sufficiently exerting the effect of improving fuel economy.
    SOLUTION: When detected variation in lift amount and detected variation in working angle between cylinders are larger than a reference value, a mean value of valve closing timing of an intake valve on the most advanced side and valve closing timing of the intake valve on the most delayed side is calculated (a step 112). Target valve closing timing of the intake valve is set so that the calculated mean value becomes the bottom dead center (a step 114). Since the variation in position of a piston in closing the intake valve becomes minimum, the variation in intake air amount between cylinders is sufficiently suppressed. Valve closing timing of an exhaust valve is set to be the same as valve opening timing of the intake valve or to be on the more delayed side than the valve opening timing of the intake valve (a step 116).

    Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection control device capable of sufficiently improving the fuel consumption and the exhaust emission in starting an engine in the cylinder injection-type spark ignition internal combustion engine.
    SOLUTION: When the engine is started, the homogeneous combustion is performed first by starting the fuel injection from an auxiliary fuel injection valve 9 injecting the fuel into an engine intake system, without injecting the fuel by a main fuel injection valve 7 for directly injecting the fuel into a cylinder, and then the fuel injection of the later half of a compression stroke by the main fuel injection valve is started to execute the stratification combustion after the fuel injection of the later half of the compression stroke by the main fuel injection valve becomes available following the rise of the fuel pressure in an accumulation chamber 20 after the first explosion.

    Abstract: PROBLEM TO BE SOLVED: To provide a negative pressure control device and a control method for internal combustion engine capable of ensuring a sufficient negative pressure at a brake booster without causing a damage at an operation of the internal combustion engine. SOLUTION: A brake booster 18 for increasing a brake step force making an intake manifold negative pressure generated in a suction passage 34 at the downstream side of a throttle valve 36 as a motive power source is provided. A pressure sensor 38 for outputting a signal corresponding to a brake negative pressure BVAC applying to a negative pressure chamber 22 is arranged at a negative pressure accumulation tank 32 provided on the way of a negative pressure feed piping 26 for communicating the negative pressure chamber 22 of the brake booster 18 with a surge tank 28. In the case where the brake negative pressure BVAC is lacked at the time when a starting of internal combustion engine is begun, the internal combustion engine 10 blown up to a higher rotation as compared with a first idle state. Thereafter, the throttle valve 36 is maintained to a whole close state at a period until the internal combustion engine 10 is transferred to the first idle state.

    Abstract: PROBLEM TO BE SOLVED: To provide a cylinder injection type spark ignition internal combustion engine capable of securing engine start, and preventing deterioration of combustion due to lowering of fuel pressure in a accumulator after the engine start. SOLUTION: This cylinder injection type spark internal combustion engine has a plurality of cylinders, and the plurality of cylinders is divided into at least a first cylinder group #1 and #2, and a second cylinder group #3 and #4. Fuel is supplied to the first cylinder group from a first accumulator 51, and fuel is supplied to the second air cylinder group from a second accumulator 52. An engine driven type high pressure pump 11 is connected to the first pressure accumulator and the second accumulator, and another booster mechanism 20 is also connected to the first accumulator. The booster mechanism raises the fuel pressure in the first accumulator to the fuel pressure for enabling favorable fuel injector at the engine start.
