    Abstract: An internal combustion engine is equipped with a variable valve control system which is operable to selectively actuate an engine valve using one of two cams of a camshaft, by sliding a rocker arm in the axial direction of a rocker-arm shaft. The system is capable of restricting the axial-direction movement of the rocker arm within a predetermined range, using a simple structure without unduly increasing the number of component parts. Position-restriction portions are formed in a rocker arm, and abut on a trigger arm to restrict sliding movement of the rocker arm within a predetermined amount, when the trigger arm is disengaged from the rocker arm.

    Abstract: An object of the invention is to reduce an HC generated in a so-called fast idle period in which an engine and a catalyst are warmed up, stabilize a combustion and achieve an early activation of the catalyst, at a cold starting time of a cylinder injection type engine. In a control apparatus controlling a cylinder injection type internal combustion engine directly feeding a fuel into a combustion chamber by a fuel injection apparatus attached to a portion near an intake valve, the control apparatus controls the fuel injection apparatus so as to carry out an intake stroke injection, makes a lift amount of an intake valve smaller than a lift amount at a time of a high load, and controls such that an opening timing of the intake valve comes closer to an intake stroke side near an intake top dead center, in a fast idle period of the cylinder injection type internal combustion engine.

    Abstract: There was a problem that various fuel spray shapes cannot be obtained according to operating conditions of a direct injection engine. There is provided a giant magnetostrictive element type injector which controls the change rate (rising slope) or peak value of a supply current applied to a solenoid for magnetic field generation which displaces a giant magnetostrictive element according to requests of an engine. The steeper the rising slope of the supply current to the solenoid, the higher becomes a lifting speed of a plunger, the higher becomes the initial speed of a fuel spray, and the longer the penetration can be. The gentler the rising slope thereof, the lower becomes the lifting speed of the plunger, the lower becomes the initial speed of the fuel spray, and the shorter the penetration can be. Further, the larger the peak value of the supply current, the larger the lift amount of the plunger can be and the larger becomes the fuel flow rate, allowing an increase in fuel spray density (resulting in a fuel spray that is not easily crushed). The smaller the peak value of the supply current, the smaller becomes the fuel flow rate, allowing a decrease in fuel spray density (resulting in a fuel spray that is easily crushed).
