摘要： The ignition system (10) of an engine (particularly for a UAV) has a primary (10a), and a secondary (10b) ignition system to provide redundancy for ‘get you home’ capability should the primary ignition system fail. The secondary ignition provides a lower energy or shorter duration spark than the higher energy or longer duration sparking of the primary ignition system, and is retarded relative to primary sparking. Timing of the secondary sparking can be advanced in the event of primary sparking failure. Fuelling strategy can be shifted from a leaner stratified charge to a richer homogenous charge when relying just on the secondary ignition system for ignition. The secondary ignition system can be of a lower spark energy and/or duration than the primary ignition system, avoiding the cost, complexity and weight of replicating the primary ignition system, and to improve packaging within the engine housing, particularly within the limited payload and space limits of a UAV.

摘要： A corona ignition system including a corona igniter, an energy supply, and a frequency detector is provided. The energy supply provides energy to the corona igniter during corona events which are spaced from one another by idle periods, during which no energy is provided to the corona igniter. During the idle periods, the frequency detector obtains the resonant frequency of the corona igniter from at least one of an output voltage and an output current of the energy stored in the corona igniter. The resonant frequency measured during this idle period is dependent only on the corona igniter, and not any other components of the system, and thus is very accurate. The drive frequency of future corona events can then be set based on this accurately measured resonant frequency to achieve a robust corona discharge.

摘要翻译：提供了包括电晕点火器，能量供应器和频率检测器的电晕点火系统。能量供应在电晕事件期间为电晕点火器提供能量，这些电晕点火器彼此间隔着空闲周期，在此期间电晕点火器没有能量供应。在空闲期间，频率检测器从存储在电晕点火器中的能量的输出电压和输出电流中的至少一个获得电晕点火器的谐振频率。在此空闲期间测量的谐振频率仅取决于电晕点火器，而不依赖于系统的任何其他组件，因此非常准确。然后可以基于这种精确测量的谐振频率设置未来电晕事件的驱动频率，以实现稳健的电晕放电。

摘要： Ignition delay in a diesel engine is reduced or eliminated by a fuel injector or igniter nozzle which includes energy supplying fuel conditioning means at the point of fuel injection into a cylinder. A preferred embodiment includes an electrically-conductive injection valve reciprocable in a conductive nozzle body and seatable on a valve seat to stop fuel flow through nozzle orifices. The injection valve is electrically insulated from the body except at its contact with the valve seat and is connected to an electrical charge, at least during opening of the valve. An electrical spark discharge is thus generated between the injection valve and the valve seat upon opening of the valve. Initially injected fuel passes through the arc and is conditioned by the spark energy to ignite almost immediately by compression ignition upon entering the engine cylinder and thus essentially eliminate diesel ignition delay.
摘要翻译：通过燃料喷射器或点火器喷嘴减少或消除柴油发动机中的点火延迟，燃料喷射器或点火器喷嘴包括在燃料喷射到气缸中的点处的能量供应燃料调节装置。优选的实施例包括导电喷射阀，该导电喷射阀可在导电喷嘴主体中往复运动并且可在阀座上定位，以阻止燃料通过喷嘴孔流动。喷射阀除了与阀座的接触之外与主体电绝缘，并且至少在阀的打开期间连接到电荷。因此，在打开阀时，在喷射阀和阀座之间产生电火花放电。最初喷射的燃料通过电弧并被火花能量调节，以便在进入发动机气缸时几乎立即点燃，从而基本消除柴油点火延迟。

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： In an ignition control apparatus (30), a control unit (319) controls switching elements so as to supply a primary current to the other end side of a primary winding (311a) opposite to one end thereof connected to a DC power source (312) by discharging (which is performed by turning on a second switching element (314) stored energy from a capacitor (317) during ignition discharge (which is started by turning off a first switching element (313). In particular, the control unit controls the second switching element or the third switching element so as to provide variability to the amount of stored energy discharged from the capacitor according to an operating state of an internal combustion engine.

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。
