Abstract
Изобретение относитс к машиностроению и позвол ет повысить вихре- образование путем уменьшени аэродинамического сопротивлени системы, а также снизить стоимость изготовлени впускных систем. Система впуска содержит по меньшей мере два впускных канала 1 и 2, расположенных на разной высоте под углом к надклапан- ной камере 3, и дроссельную заслонку 4, размещенную в верхнем впускном канале 1, тангенциально сопр женном с надклапанной камерой 3. Последн выполнена в виде тела вращени , впускные каналы в местах сопр жени с надклапанной камерой вьшолнены цилиндрическими , а нижний канал сопр жен с надклапанной камерой тангенциально , причем сопр жени впускных каналов с надклапанной камерой расположены с разных сторон относительно ее оси. На режимах частичных нагрузок заслонка 4 впускного канала 1 закрыта, и рабочий зар д поступает в цилиндр двигател по впускному каналу 2, тангенциальное расположение которого относительно камеры 3 обеспечивает интенсивное завихривание зар да. При работе двигател на режиме полной мощности заслонка 4 открыта и верхний впускной канал 1 образует вихрь, противодействующий и направленный под некоторым углом к вихрю, образованному нижним каналом 2, а суммарна интенсивность вихр минимальна. При этом в результате взаимодействи двух направленных под некоторым углом вихрей поток рабочего тела турбулизуетс , что повышает интенсивность сгорани . 3 з.п. ф-лы, 3 ил. % (Л с ел елThe invention relates to mechanical engineering and allows increasing the vortex formation by reducing the aerodynamic resistance of the system, as well as reducing the manufacturing cost of the intake systems. The intake system contains at least two inlet channels 1 and 2 located at different heights at an angle to the supra-valve chamber 3, and a throttle valve 4 placed in the upper inlet channel 1 tangentially associated with the suprapalted chamber 3. The latter is made in the form The bodies of rotation, the inlet channels in the places of interface with the supravalanal chamber are filled with cylindrical, and the lower channel are conjugated with the suprapalanted camera tangentially, and the conjugations of the inlet channels with the suprapalar chamber are located on different sides its axis. In partial load modes, the damper 4 of the intake channel 1 is closed, and the working charge enters the engine cylinder through the intake channel 2, the tangential position of which relative to the chamber 3 provides for an intense turbulence of the charge. When the engine is operating at full power, the flap 4 is open and the upper inlet channel 1 forms a vortex, opposing and directed at a certain angle to the vortex formed by the lower channel 2, and the total intensity of the vortex is minimal. At the same time, as a result of the interaction of two vortices directed at a certain angle, the flow of the working fluid is turbulized, which increases the intensity of combustion. 3 hp f-ly, 3 ill. % (L ate
