    摘要: In a general aspect, an ignition circuit can include a control circuit that is coupled with an engine control unit (ECU) to receive a command signal from the ECU. The control circuit can include a multi-pulse generator configured to, in response to the command signal, generate a multi-pulse drive signal. The multi-pulse drive signal can include a first pulse cycle having a first duty cycle, a second pulse cycle having a second duty cycle, and a dwell period during which the multi-pulse drive signal continuously remains at a logic high value. The control circuit can be configured to provide the multi-pulse drive signal to an ignition switch coupled with the control circuit to receive the multi-pulse drive signal.

    摘要: An igniter includes a switch element and a switch control apparatus. An ignition signal IGT is input to an input line of the switch control apparatus. A high-frequency filter removes high-frequency noise from the input line. A voltage comparator compares an output voltage VFIL of the high-frequency filter with a reference voltage VREF, so as to generate a judgment signal SDET. A driving stage controls an on/off switching operation of the switch element according to the judgment signal SDET. An off-state dead-time circuit prohibits the switch element from turning off during a predetermined dead time after the judgment signal SDET transits to a negated level that corresponds to the off state of the switch element.

    摘要: A high frequency generating device used in a plasma ignition apparatus according to an embodiment includes a high frequency output unit, an output control unit, a current detecting unit, and an abnormality detecting unit. The high frequency output unit outputs a high frequency. The output control unit shifts a state of the high frequency output unit from a non-output state to an output-ready state of the high frequency. The current detecting unit detects a current that flows through a power-supply path to the high frequency output unit. The abnormality detecting unit detects output abnormality of the high frequency in the non-output state when a value of a current detected by the current detecting unit in the non-output state exceeds a non-output threshold.

    摘要: The size of the plasma produced by a plasma-generating device that generates plasma using electromagnetic (EM) radiation is enlarged. The plasma-generating device has an EM-wave-generating device that generates EM radiation, a radiation antenna that emits the EM radiation supplied from the EM-wave-generating device to a target space, and a receiving antenna located near the radiation antenna. The receiving antenna is grounded such that an adjacent portion that is close to the radiation antenna has a higher voltage while the EM radiation is emitted from the radiation antenna. The plasma-generating device generates plasma in the target space near the radiation antenna and the adjacent portion by emitting EM radiation from the radiation antenna.

    摘要: An engine control unit with distributed processing includes a main ECU and remote modules with sensor inputs and ignition and injector outputs. A bidirectional asynchronous CAN data bus and a square wave timing signal operatively connect the components. Synchronous ignition and ignition data and asynchronous sensor and control data are concurrently transmitted between components using CAN messaging. Synchronicity is accomplished using the timing signal. The rising edge of each pulse triggers dwell and injection start times, and the falling edge triggers ignition. Injection and dwell time values, the cylinders to dwell and fire, and the injectors to energize, are transmitted using CAN messaging. The remote modules process the control messages and timing signal and generate the appropriate ignition, injector, and pulse width modulation control signals. Alternatively, time stamp capabilities of the CAN bus topology are used for synchronization. The system and methodology simplify interconnection, using fewer wires and enhancing aesthetics.
