    Abstract: A method for heating an exhaust pipe in a motor vehicle, including a plurality of spark cycles performed in succession at a preset frequency, wherein each spark cycle includes injecting a-preset fuel quantity into an injection area inside of an exhaust pipe in a motor vehicle and generating at least one spark between the ends of a pair of electrodes located in proximity to the injection area in order to start combustion.
    Thus, a value of an ionization current flowing between the ends of the pair of electrodes is detected following the extinction of the spark and this ionization current value is compared with a preset reference value.
    Therefore, the presence of combustion in the spark cycle is determined, if the ionization current value is greater than the preset reference value, or the absence of combustion in the spark cycle, if the ionization current value is lower than the preset reference value.

    Abstract: It is disclosed an electronic device to control an ignition coil of an internal combustion engine comprising a high-voltage switch, a driving unit, a bias circuit and an integrating circuit. The high-voltage switch is connected in series with a primary winding of a coil. The driving unit is configured to control the closing and opening of the high-voltage switch. The integrating circuit is interposed between the bias circuit and a reference voltage. The integrating circuit comprises an integrating capacitor. The integrating capacitor is configured, in the case wherein a pre-ignition of the comburent-combustible mixture in the combustion chamber during the phase of charging occurs, to pre-charge during the phase of charging energy in the primary winding and it is configured, in the case wherein the pre-ignition of the comburent-combustible mixture does not occur, to maintain the charge state substantially constant during the phase of charging energy.

    Abstract: An electronic ignition system for an internal combustion engine. The system includes a coil having a primary winding with a first terminal and a second terminal and a secondary winding connected to a spark plug. A high voltage switch is serially connected to the primary winding. A control terminal carries a control signal to control the opening or closing of the high voltage switch. A first switch is interposed between a battery voltage and the first terminal of the primary winding, a second switch is interposed between the first terminal of the primary winding and a reference voltage, a third switch is interposed between the second terminal of the primary winding and said reference voltage. A driving unit is configured to generate signals to control the switches during a charging phase, during a transfer of energy phase, and during a measure phase of ionization current.
