摘要： PROBLEM TO BE SOLVED: To prevent deterioration of torque control accuracy in ignition retard control in a variable valve engine in view of that a combustion speed of an air-fuel mixture is largely varied by variation of internal EGR (exhaust gas recirculation quantity) accompanied by valve overlap enlargement and an ignition timing efficiency curve is easily changed in accordance with an operation range when a variable valve engine for variably controlling valve timing and lift in accordance with the operation range is used, and therefore, the conventional technology for performing ignition retard control by a single ignition timing efficiency table cannot cope with the ignition timing efficiency variation, and control accuracy of engine torque is deteriorated. SOLUTION: When performing torque down control by ignition retard, combustion timing is calculated in consideration of valve timing and engine speed in the operation state, and a characteristic of the ignition timing efficiency curve as a reference is corrected based on the difference between the combustion timing and a combustion timing reference value set in advance.

摘要： PROBLEM TO BE SOLVED: To constantly control torque with high accuracy even if the torque developing efficiency of a control parameter related to engine torque is greatly changed depending on an operation area.
SOLUTION: When an engine is controlled, this control device for an engine compensates the engine torque by calculating target torque when changing the control parameter related to the engine torque and adjusting the other control parameter related to the engine torque based on the target torque. Before the other control parameter is adjusted, an operating state when it is assumed that the other control parameter is adjusted is predicted, and predicted developing torque in the predicted operating state is calculated. When deviation between the target torque and the predicted developing torque reaches a predetermined value or larger, a variation in the control parameter is changed and operations of the target torque and predicted developing torque are recalculated.

摘要： PROBLEM TO BE SOLVED: To change variously fuel spray shapes according to an operating condition of a direct fuel injection type engine.
SOLUTION: There provided is a supermagnetostrictive element type injector which controls a rate of change (a rising gradient) in supply current applied to a solenoid for generating a magnetic field that displaces a supermagnetostrictive element or controls a peak value in response to an engine demand. In the supermagnetostrictive element type injector, the larger the rising gradient of the supply current to the solenoid, the faster the lifting velocity of a plunger to permit an spraying initial velocity to be faster, thus enabling penetration to be lengthened. Then, the smaller the gradient thereof, the slower the lifting velocity of the plunger to slow the spraying initial velocity, thus enabling the penetration to be shortened. Further, the higher the peak value of the supply current is rendered, the larger the lifting amount of the plunger can be rendered, to increase a fuel flow volume, thus enabling the spraying to be denser and hard to get crushed. Furthermore, the lower the peak value of the supply current, the smaller the fuel flow volume, enabling the spraying to decrease in density (the spraying easy to get crushed).
