摘要： An ignition unit (4) of an internal combustion engine (1) is equipped with an ignition coil (21) including a primary coil (21a) and a secondary coil (21b), an igniter (22), and a secondary current detection resistor (23). By means of the secondary current detection resistor (23), an engine controller (10) detects a current value (Idis) of the secondary current immediately after completion of capacitive discharge. The current value (Idis) is correlated with a gas pressure between electrodes at ignition timing, and thus an in-cylinder pressure (Pign) can be estimated from the current value (Idis). An amount of time-dependent change (”µ) in compression ratio, caused by accumulation of deposits, is calculated based on the in-cylinder pressure (Pign) at the ignition timing.

摘要： An ignition apparatus includes a cylindrical core made from magnetically-permeable material and a C-shaped magnetic return path structure that is made from a stack of silicon steel laminations. A tightly controlled air gap is provided between one leg of the C-shaped structure and an end face of the core, forming a magnetic circuit having a high magnetic permeability, which overall reduces the number of primary winding turns needed, thereby reducing the amount of copper wire. In addition, the circular cross-section of the core reduces the mean length per turn (MLT) of the primary winding because the primary winding can be wound directly on the core, which in turn also reduces the MLT of the secondary winding. The reduced MLT also reduces the amount of copper wire. The structure may be replaced using a magnetically-permeable, U-shaped shield.
摘要翻译：点火装置包括由导磁材料制成的圆柱形芯和由一叠硅钢叠层制成的C形磁返回路径结构。在C形结构的一条腿和芯的端面之间设置紧密控制的气隙，形成具有高磁导率的磁路，这总体上减少了所需的初级匝数，从而减少了铜线。此外，由于初级绕组可以直接缠绕在芯上，芯的圆形横截面减小了初级绕组的平均长度（MLT），这又降低了次级绕组的MLT。减少的MLT也减少了铜线的数量。该结构可以使用磁性可渗透的U形屏蔽来代替。

摘要： A control apparatus for an internal combustion engine according to the present invention includes a spark plug (30) for igniting an air-fuel mixture in a cylinder, and is configured to be capable of measuring a discharge voltage of the spark plug (30). The control apparatus calculates a turbulence intensity index value that indicates the turbulence intensity of in-cylinder gas based on a predetermined frequency component extracted from a discharge voltage during at least a part of a discharge duration leading up to ignition and, in accordance with the turbulence intensity index value, adjusts the ignition energy that is supplied to the spark plug (30) during a combustion duration in a cycle in which the turbulence intensity index value is calculated.

摘要： To alleviate or eliminate a problem of unburned fuel discharged to the outside of a cylinder in a case in which an air fuel mixture is insufficiently combusted in a combustion chamber. During the expansion stroke in which a high voltage is applied to an ignition plug via an ignition coil, and a spark discharge is caused to occur at the ignition plug, thereby the air fuel mixture in the combustion chamber is ignited and combusted, in a case in which deterioration of combustion state is detected, a microwave electric field is created in the combustion chamber prior to an opening timing of an exhaust valve at an end stage of the expansion stroke, thereby plasma is generated and enlarged in the combustion chamber.

摘要： An ignition system for an internal combustion engine comprises an ignition transformer with two primary windings (L P1 , L P2 ). The ignition system is designed to generate, for a given ignition event, a unipolar current (I SEC ) through the secondary winding (L SEC ) by way of a control circuit (20) that is configured to first energize and deenergize the first primary winding (L P1 ) to establish a first electrical arc across the spark-plug electrodes (14) and, when the current (I SEC ) in the secondary winding reaches, or drops below, a current threshold (I SEC_TH ), repeatedly energizes and deenergizes the second primary winding (L P2 ) to establish a plurality of second current pulses across the electrodes in order to maintain the burn phase.
