INTERNAL COMBUSTION ENGINE START-UP SYSTEM Russian patent published in 2011 - IPC F02N11/08 

FIELD: engines and pumps.

SUBSTANCE: internal combustion engine (ICE) start-up system includes storage battery (1), ignition switch (2), starter (3), first (4) and second (5) diodes, current-limiting resistor (6) and capacitive energy storage (1). The latter (1) is charged from the first output of storage battery (1) through in-series connected current-limiting resistor (6) and the first diode (4). The second outputs of storage battery (1) and energy storage (1) are connected to each other and form negative bus of power supply (1). The first power contact of starter (3) is directly connected to the first output of storage battery (1). The second power contact of starter (3) is connected to negative bus of power supply (1). Pin of starter (coil of pulling switch) is connected through ignition switch (2) to connection point of current-limiting resistor (6) and cathode of the first diode (4). Anode of the second diode (5) is connected to the first output of capacitive energy storage (7). Cathode of the second diode (5) is connected to connection point of current-limiting resistor (6) and cathode of the first diode (4).

EFFECT: design optimisation of internal combustion engine start-up system.
