Claims (4)

1. Способ работы судового малооборотного дизеля с прямоточно-клапаной схемой газообмена и устройство камеры сгорания для его осуществления, включающий наполнение и сжатие свежего заряда воздуха, впрыск топлива двумя форсунками, смесеобразование, сгорание, рабочий ход, выпуск отработавших газов, отличающийся тем, что впрыск топлива осуществляют по двум диаметрально противоположным направлениям и факелы распыла перпендикулярны оси цилиндра, а выпуск отработавших газов начинают при угле поворота коленчатого вала не более 55° до НМТ и заканчивают при угле поворота не более 55° после НМТ.1. The method of operation of a ship low-speed diesel engine with a direct-flow valve gas exchange scheme and a combustion chamber device for its implementation, including filling and compressing a fresh air charge, fuel injection with two nozzles, mixture formation, combustion, stroke, exhaust gas discharge, characterized in that the injection fuels are carried out in two diametrically opposite directions and the spray flames are perpendicular to the axis of the cylinder, and the exhaust gas is started at an angle of rotation of the crankshaft of not more than 55 ° to the BDC and night with a rotation angle of not more than 55 ° after BDC. 2. Способ по п.1, отличающийся тем, что за счет увеличения диаметра и проходного сечения выпускного клапана осуществляется более позднее начало его открытия, в результате чего увеличивается индикаторная работа газов за цикл и индикаторный КПД двигателя.2. The method according to claim 1, characterized in that by increasing the diameter and the bore of the exhaust valve, a later start of its opening is carried out, as a result of which the indicator work of gases per cycle and the indicator engine efficiency are increased. 3. Устройство камеры сгорания судового малооборотного дизеля с прямоточно-клапанной схемой газообмена, включающее полуколпачкового типа крышку цилиндров с выпускным клапаном в центре, две форсунки для впрыска топлива, поршень, отличающееся тем, что форсунки расположены на диаметрально противоположных сторонах цилиндрической части крышки перпендикулярно оси цилиндра, при этом увеличен диаметр и проходное сечение выпускного клапана, а днище поршня выполнено плоским.3. The combustion chamber of a marine low-speed diesel engine with a direct-flow valve gas exchange scheme, including a half-cap type cylinder cover with an exhaust valve in the center, two nozzles for fuel injection, a piston characterized in that the nozzles are located on diametrically opposite sides of the cylindrical part of the cover perpendicular to the cylinder axis while increasing the diameter and the bore of the exhaust valve, and the piston bottom is made flat. 4. Устройство по п.3, отличающееся тем, что факелы распыла топлива от двух форсунок направлены навстречу друг другу, а длина факела должна быть не более радиуса цилиндра.4. The device according to claim 3, characterized in that the fuel spray from the two nozzles are directed towards each other, and the length of the flame should be no more than the radius of the cylinder.
