Abstract: The invention relates to a method and device for controlling an internal combustion engine comprising an inlet pipe leading to a cylinder input where a gas input valve is placed. Said engine also comprises a drive for the gas input valve which makes it possible to adjust a gas input valve lift for at least two values. The engine also comprises an injection valve for metering fuel and a spark plug which controls the crankshaft angle of air-fuel mixture ignition. Said internal combustion engine is controlled in a following manner: a fuel is metered at least once during the intake stroke of a cylinder when the valve lift (VL) passes from one value to the other and at least one final injection is carried out in a dosing manner only when the valve lift (VL) is really carried out.

Abstract: An internal combustion engine is equipped with a variable actuation system for the intake valves including a chamber of fluid under pressure interposed between the intake valve and the respective controlling cam, and a solenoid valve whose opening causes the pressure chamber to discharge such as to determine the rapid closure of the valve by effect of the respective biasing spring means, even when the respective cam would tend to keep the valve open. The variable valve operation system is used in combination with the use of cams controlling the intake valves shaped in such a manner as to give rise to an intake valve lift profile including a boot portion at substantially constant lift. Such boot portion is provided in the initial part of the intake valve opening cycle, in advance with regard to the TDC, in the case of a supercharged direct-injection petrol engine. In the case of a diesel engine, on the contrary, the boot portion is provided in the final part of the intake valve opening cycle, after the BDC.

Abstract: A method for distributing lock pin ejections evenly over all the switchable mechanisms in a plurality of switchable mechanisms: establishing a limiting number of lock pin ejections; designating a primary switchable mechanism for the mode change upon command from an engine control module (ECM); employing the designated primary switchable mechanism until the limit is reached; designating another switchable mechanism a primary; employing the second primary mechanism until the limit is reached again; and designating sequentially each of the remaining switchable mechanisms as primary switchable mechanisms, each until the limit is reached again. The ECM counts the activation commands and switches the primary designation when the limit is reached so that each mechanism has the same exposure to ejections, and the number of ejections per mechanism is evenly distributed. If ejection detection means is available, the ECM may accumulate actual ejections for each mechanism and schedule the primary designation change thereupon.

Abstract: A method of controlling an intake air passage of an internal combustion engine is provided. The intake air passage cyclically communicates to a combustion chamber of the internal combustion engine, thereby inducting fresh air into said combustion chamber. The cyclic communication of the intake air passage to the combustion chamber generates a pressure wave in the intake air passage. The method comprises reducing an effective length of a transmission path of the pressure wave in an upstream direction of the intake air passage as a desired air flow to the combustion chamber decreases. In accordance with the method, the effective length of the pressure wave transmission path is reduced as desired air flow decreases. With the reduced effective length, the pressure wave bounces back and forth between ends of the transmission path more often before the next cyclic communication. The more bouncing attenuates the pressure wave at the next cyclic communication. Therefore, the cylinder air charge can be stabilized when the desired air flow is decreased.

Abstract: An internal combustion engine having cylinders capable of selectively resting during engine operation is capable of eliminating step increases in engine output when the number of operative cylinders is changed. The internal combustion engine includes a plurality of cylinders divided into two or more groups, at least some of the cylinders being restable. A throttle valve of each of the cylinders is independently operable on the basis of the group to which the cylinder belongs, and the number of resting cylinders is controlled according to the throttle grip opening. The throttle valve opening is different between the groups, except for the full opening condition and the full closure condition of the throttle valve, and an ECU is provided for opening the throttle valve of the next cylinder group before the throttle valve opening of the former cylinder group reaches the full opening condition.
