SYSTEM FOR ELECTRIC STARTING OF INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

FIELD: automotive industry. SUBSTANCE: system had battery 1, starter 2 constructed as DC electric motor, low-voltage capacitor battery 7, device for controlling starting provided with the relay having normally open contact 4 and diode 8, anode coupled to the positive pole of battery 7, high-voltage capacitor battery 14 the operating voltage of which at least is two times higher than the voltage of the storage battery, voltage converter 15 with low-voltage and high-voltage leads, switching unit 13 with two normally closed and one normally open contacts, two additional diodes 7 and 10, smoothing throttle 11 and current transformers 12 mounted on the supplying wire of the starter and connected with the input of the switching unit. The positive output of the low-voltage battery is connected to one of the low- voltage outputs of the voltage converter and to the starter through the first diode, throttle and relay contact connected in series. The negative output is connected with the other low-voltage output of the voltage converter through the first normally closed contact of the switching unit. The positive output of the high-voltage capacitor battery is connected with one of the high-voltage outputs of the voltage converter and to the point of connection of the throttle with the cathode of the first additional diode through normally open contact of the switching unit and the second additional diode connected in series. The negative output is connected with the negative output of the storage battery and with the other high-voltage output off the voltage converter through the second normally closed contact of the switching unit. The cathode of the first diode is connected with the point of connection of the first additional diode and throttle. When the crankshaft of the engine begins to rotate owing to the energy of the low-voltage capacitor battery, the high- voltage battery connected in a time delay through a smoothing filter rapidly and smoothly accelerates the crankshaft up to the higher speed of rotation. EFFECT: enhanced reliability. 2 dwg
