Abstract: Provided is an engine control device which can suppress a shortage of output terminals of the control unit and an increase of costs even in a multiple-cylinder internal combustion engine equipped with ignition energy supply units of two systems. An engine control device controls a multiple-cylinder engine in which ignition energy supply units of two systems are provided for every cylinder. A signal is transmitted through a common signal line to a plurality of ignition energy supply units of one system among the ignition energy supply units of the two systems to control the ignition energy supply units of the one system.

Abstract: In an ignition coil for an internal combustion engine, a spark plug is incorporated which has an insulator including an insulator head that has no corrugation. The ignition coil has a coil body part generating high voltage and a joint part, which holds therein a conducting member electrically connecting the coil body part and a spark plug. The joint part has a plug cap into which the insulator head of the spark plug is inserted and which is formed of an elastic member having a cylindrical shape. The plug cap has a close-contact part whose inner peripheral surface is closely brought into contact with an outer peripheral surface of the insulator. The close-contact part has a tip end-side close-contact part positioned at a tip end side with respect to a middle position in an axial direction, and a base end-side close-contact part positioned at a base end side with respect to the middle position. At least part of the base end-side close-contact part is provided with a strong strained force part that has strained force for fastening the insulator head, the strained force being stronger than strained force of all portions of the tip end-side close-contact part.

Abstract: Operating a gaseous fuel engine includes injecting a pilot charge directly into a combustion chamber in an engine, and igniting one spray plume of the pilot charge. A flame front is propagated to other pilot spray plumes to produce an ignition flame for igniting later injected main charge spray plumes. Injection of the pilot and main charges is by way of the same fuel injection orifices.
