METHOD TO START UP INTERNAL COMBUSTION ENGINE AND STARTER FOR ITS REALISATION Russian patent published in 2014 - IPC F02N5/04 

FIELD: engines and pumps.

SUBSTANCE: invention relates to the field of propulsion engineering, namely, to start-up of piston internal combustion engines (ICE) of transport machines. The substance of the invention consists in the fact that the first electric motor 1 is used to speed up a flywheel 2, and then an electromagnetic coupling 3 is switched on, transferring torque from the flywheel 2 to the ICE shaft through it. Simultaneously with speeding of the flywheel 2 they rotate the ICE shaft by the second electric motor 6, besides, at the first moment of time the electromagnetic coupling 3 is shortly started, provided that the rotor of the second electric motor 6 is fixed. At the following second moment of time the electromagnetic coupling 3 is started, provided that the average speed of rotor rotation in the second electric motor 6 exceeds the specified level, in the opposite case the electromagnetic coupling 3 is switched on at the following third moment of time. The starter comprises the first electric motor 1 with the flywheel 2, connected via the electromagnetic coupling 3 and the reducer 4 with an output shaft, on which a driving gear 5 is installed. Besides, the reducer 4 is placed between the electromagnetic coupling 3 and the driving gear 5, and also the second electric motor 6, the rotor of which is installed on the shaft that connects the electromagnetic coupling 3 and the reducer 4.

EFFECT: increased reliability of start-up under various temperatures of environment.
