Description

The invention relates to mechanical engineering, in particular to engine-building, namely to starting devices of internal combustion engines, and can be used on vehicles.

The purpose of the invention is to increase the reliability of engine start.

The drawing shows the electrical circuit of the proposed device.

The electric starter includes a battery 1, a starter 2 with a high-voltage winding (not shown) core, a brush-collector node 3, a high-voltage excitation series winding 4, an additional low-voltage winding (not shown) core, a second brush-collector node 5 and an additional low-voltage serial winding 6 excitation. The device also contains a capacitor battery 7, a voltage converter 8, a pull relay 9 with closing contacts 10 and 11, a starter switch 12. The capacitor battery 7 is connected to the battery 1 via the voltage converter 8, the high-voltage starter excitation winding 4 is connected to the capacitor battery 7 via the closing contact 10 t of the relay 9 that is connected to the battery 1 via a switch

12 starter, the additional low-voltage winding 6 of the starter is connected to the battery 1 via an additional closing contact 11 of the relay 9. The device can be equipped with keys 13 and 14. The key 13 is installed between the capacitor battery 7 and the high-voltage winding 4 of the starter, and the key 14 is between the accumulator battery 1 and the excitation low-voltage winding 6.

The device works as follows.

Before starting the engine, the capacitor battery 7 is charged by the battery 1 through the voltage converter 8. After charging the capacitor battery 7 to the required voltage value, the converter 8 stops operation.

The keys are locked for engine start.

13 and 14 and the starter switch 12 is pressed. The fuse relay 9 operates and closes contacts 10 and 11. At the same time, the starter 2 is energized from two sources:

the high voltage is supplied from the capacitor battery 7 and the low battery from battery 1. The capacitor battery 7 is discharged through the high voltage winding 4 and the high voltage winding of the core. The battery on the battery is discharged through an additional low-voltage field coil 6 and an additional box coil. Engine scrolling occurs

internal combustion.

Using the keys 13 and 14, you can disconnect the high-voltage or low-voltage power supply circuit of the starter 2, choose various options for the proposed

Devices: start from a battery, start from a capacitor battery, start from two energy sources.
