FIELD: engines and pumps.
SUBSTANCE: method for increasing the dispersion of injected fuel into the combustion chamber (2) of internal combustion engine (ICE) by fuel injector single-stroke drive with a drive battery (6) for charging with working medium, liquid or gas, compressed air or fuel mixture in the ICE combustion chamber (2). The ICE includes an engine control system, a spool (14) for working medium flow control, the drive battery (6), a piston (17) of the fuel injector single-stroke drive and two pistons (21, 25) of the fuel injector. The ICE control system sets the spool (14) for working medium flow control to the position at which the working medium from the drive battery (6) is supplied to one of the piston cavities (17) of the fuel injector single-stroke drive. The piston (17) of the fuel injector single-stoke drive starts to move in opposite direction, connects to the plunger (21, 25) of the fuel injector, and arrives to the extreme point of motion together with it. As a result, a fuel dose is injected in the ICE combustion chamber (2). After the arrival of the piston (17) of the fuel injector single-stroke drive and the plunger (21, 25) of the fuel injector in the extreme point of motion, the ICE control system turns the spool (14) for working medium flow control to the position at which the working medium from the drive battery (6) enters the opposite cavity of the piston (17) of the fuel injector single-stroke drive. The piston (17) of fuel injector single-stroke drive starts moving in opposite direction, connects to the plunger (21, 25) of the fuel injector and together with it arrives to the extreme point of motion. As a result, the next fuel dose is injected into the ICE combustion chamber (2).
EFFECT: increased dispersion degree of fuel supplied at initial phase into the combustion chamber.
