FIELD: engine engineering. SUBSTANCE: circuit is formed of voltage doubler with rectification and unit for charge accumulation connected to it. The doubler is based on two diodes. Each of the diodes is connected with a resistor in parallel. The charge accumulation unit is made up as two accumulation capacitors connected in series. One of the inputs of the circuit is the point where the capacitors are interconnected. The other input is a point where the diodes are interconnected in parallel: cathode of the first diode and anode of the second diode. The output of the circuit used to connect the circuit to the spark ignition system (the secondary winding of the ignition coil) is a point where the cathode of the second diode and the second plate of the first capacitor are interconnected. The second plate of the other capacitor is connected with the anode of the first diode and with common supplying bus. The inputs of the circuit are connected with the outputs of the plasma ignition system, e.g., with the output of the secondary winding of the inverter transformer, the outlets being connected with the input of the spark ignition system. The polarity of the diode between the input and output of the circuit is direct with respect to the input of the spark ignition system. EFFECT: enhanced reliability. |
