摘要： A cylinder of an internal combustion engine is communicated with intake ports. Each of intake valves and each of fuel injection valves are provided to a corresponding one of the intake ports to inject fuel into a combustion chamber through a curved portion and an opening of the corresponding intake port. An injection axis of each fuel injection valve intersects with a surface of the corresponding intake valve placed in a close position at an intersecting point that is located on an upstream side of a central axis of the corresponding intake valve.

摘要： A catalyst for purifying exhaust gas is provided in an exhaust pipe of an engine. When air-fuel ratio dither control is performed, an ECU calculates a requested torque to be generated by combustion of the engine based on an accelerator opening angle or the like operated by a driver. An MBT estimated torque corresponding to MBT (Minimum advance for the Best Torque) in each case is calculated, and a spark timing retard limit estimated torque corresponding to a spark timing retard limit in each case is calculated. An air-fuel ratio amplitude amount in the air-fuel ratio dither control is calculated based on the calculated requested torque, the MBT estimated torque, and the spark timing retard limit estimated torque. An early activation of a catalyst is realized.

摘要： When a constant driving voltage is applied to a motor driving an EGR valve so that the EGR opening degree is varied, an angular speed of the EGR valve becomes minimal at a position where the driving torque of the EGR valve becomes maximal. In view of this, while an opening degree of the EGR valve is varied with a constant driving voltage applied to the motor, the EGR opening degree where the angular speed becomes minimal is learned as a full-close position.

The sub-fuel is lower than main-fuel in concentration of alcohol. Each of multiple first fuel injection valves is provided to each of the cylinders for injecting fuel. Each of multiple second fuel injection valves is provided to each of the cylinders for injecting fuel. A fuel inlet portion supplies at least sub-fuel to each of the first fuel injection valves and each of the second fuel injection valves.

摘要： In an engine torque loss computing section, a pump loss computing section computes a pump torque loss, and a frictional loss computing section computes a frictional torque loss. The pump torque loss and the frictional torque loss are summed to obtain an engine torque loss. Furthermore, a torque loss correction amount computing section computes a torque loss correction amount, and a correction amount changing section changes the torque loss correction amount based on a result of determination of whether fuel cut-off is currently executed. The torque loss correction amount is added to the uncorrected initial engine torque loss to obtain a corrected engine torque loss.

摘要： While an engine is an idling state and an EGR opening degree is increased stepwise from a specified opening degree, a variation in engine speed (a standard deviation in engine speed) is repeatedly computed. After that, a specified step amount is successively reduced from the EGR opening degree and the variation in engine speed is successively computed until the EGR opening degree becomes less than or equal to a specified value. Then, a maximum value of the EGR opening degrees where the variation in engine speed becomes minimum is learned as the full-close position.
