Ignition Device Secondary Current Control Circuit

The patent applies dynamics by making the secondary current controllable during continuous spark discharge. The energy supply circuit adjusts the secondary current based on engine operating conditions (such as engine speed and load), transforming the static current flow into a dynamic, adaptable current that optimizes both spark discharge duration and power consumption. This is achieved through control signals from the ECU that regulate the switching element in the energy supply circuit.

The patent changes the parameter of secondary current magnitude during continuous spark discharge. By varying the secondary current parameter according to engine conditions, the system maintains effective spark discharge while reducing unnecessary power consumption. The ECU monitors engine parameters and adjusts the secondary current accordingly, implementing parameter changes to resolve the contradiction between maintaining spark duration and reducing power usage.

The patent implements dynamics by enabling the energy supply circuit to adaptively adjust secondary current based on real-time engine operating conditions. The ECU receives engine parameter inputs (such as crankshaft position, engine speed, and load) and dynamically modifies the energy supply characteristics. This dynamic adjustment ensures sufficient energy delivery across varying engine speeds without requiring overly complex circuit design, as the control logic is integrated into the existing ECU.

The patent employs feedback mechanisms where the ECU continuously monitors engine operating conditions and uses this information to adjust the secondary current in the energy supply circuit. The feedback loop ensures that the ignition system responds appropriately to changing engine demands, maintaining reliable spark discharge across different operating ranges while keeping the circuit design manageable through intelligent control rather than hardware complexity.

The patent applies parameter changes by adjusting the secondary current magnitude based on engine operating conditions. At high engine speeds where higher energy is needed for reliable ignition, the ECU increases the secondary current parameter. At low engine speeds where less energy is required, the ECU reduces the secondary current parameter. This parameter adaptation resolves the contradiction by matching energy supply to actual ignition needs across different operating ranges.

The patent implements partial action by supplying only the necessary amount of energy required for reliable ignition at each operating condition. Instead of continuously supplying maximum energy, the system provides partial energy supply appropriate to the current engine state. This prevents excessive power consumption at low speeds while ensuring sufficient energy delivery at high speeds, optimizing the balance between ignition reliability and power consumption.
