1. Способ работы двигателя внутреннего сгорания с объемным смесеобразованием и воспламенением от сжатия, включающий одноразовый впрыск топлива на долевых режимах или многофазный впрыск топлива с одним основным и одним или несколькими предварительными впрысками в камеру сгорания во время фазы сгорания или непосредственно после фазы сгорания воспламенившейся предварительной смеси, отличающийся тем, что за счет управления опережением подачи топлива в цилиндр двигателя количества фаз впрыска, амплитуды давления и продолжительности впрыска, соотношения количества топлива в каждой фазе и пауз между фазами впрыска достигают совмещения фазы максимальной скорости тепловыделения с фазой максимальной скорости увеличения объема цилиндра во время рабочего хода, находящихся в диапазоне 22-25 градусов поворота коленчатого вала за ВМТ.1. The method of operation of an internal combustion engine with volumetric mixture formation and compression ignition, including a single injection of fuel in fractional modes or multiphase fuel injection with one main and one or more preliminary injections into the combustion chamber during the combustion phase or immediately after the combustion phase of the ignited preliminary mixture characterized in that due to the control of the advance of the fuel supply to the engine cylinder, the number of injection phases, pressure amplitude and duration ska fuel ratio at each phase and injection pauses between phases reach the phase combination of maximum heat release rate with the phase of the maximum rate of increase in volume of the piston during the working stroke, being in the range of 22-25 degrees of crank TDC. 2. Способ по п. 1, отличающийся тем, что количество фаз многофазного впрыска может составлять от одной до пяти.2. The method according to p. 1, characterized in that the number of phases of multiphase injection can be from one to five.
