ARRANGEMENT FOR STARTING OF DIESEL ENGINE

The invention pertains to the area of electrical engineering and may be used in transportation systems. The object of development is to minimise power losses during the start. The suggested arrangement (fig.1) consists of storage battery (1), starting generator (25, 26) and capacitor's battery (15, 16, 17, 18). Positive terminal of the storage battery with two reed relay contacts group is connected in series with the beginning of two windings winded in opposite direction as to primary winding of transformer (13). The middle point of mentioned winding is connected with negative terminal of the storage battery. Secondary winding of single-phase transformer (13) is connected in series with single-phase rectifierÆs (14) capacitor battery (15, 16, 17, 18), but separate capacitors and corresponding thyristors' (19, 20, 21, 22) switches are connected in series with starting generator (25, 26). The axle of starting generator is tied with Diesel engine accelerator's sensor (29). Sensor's output is connected to control system, which contains summing unit (30), pulse generator (31) and block (32) controlling the closing consequence of thyristors. Besides, permanent magnet (35) separated from the reed relay's contact by air gap is fixed at the oil's engine rotating shaft (34).
