FIELD: engines and pumps.
SUBSTANCE: method for dose control of fuel injected into combustion chamber 2 of internal combustion engine (ICE) is proposed, according to which the injection of fuel dose, corresponding to the load on the ICE, into the combustion chamber, the fuel injector drive control system switches a setter 26 of injected fuel dose into the corresponding position of load which is set on the internal combustion engine. The control system then monitors the actual position of the ICE piston 1 and at the moment, when it is required to supply fuel to the ICE combustion chamber, it sets the control valve 14 for controlling the working medium flow to a position, in which the working medium enters the upper space of the fuel injector drive piston 17 from accumulator 6. The fuel injector drive piston 17 moves down and connects to a fuel injector plunger 21 and moves together with it down till it rests against a projection of injector 26 of injected fuel dose, thereby fuel injected into the ICE combustion chamber corresponding to given ICE power is limited.
EFFECT: increased accuracy of dosing.
