Abstract

Изобретение относится к области машиностроения, а именно к двигателестроению. Задачей изобретения является повышение удельной мощности и топливной экономичности работы двигателя, а также снижение количества токсичных продуктов сгорания в выхлопных газах. Задача изобретения решена тем, что в форкамерном двигателе с непосредственным впрыском топлива в цилиндр и принудительным зажиганием форкамера с объемом цилиндра дополнительно соединена с помощью запального канала, выходящего в объем цилиндра у стенки цилиндра, в области над вытеснительной поверхностью днища поршня и имеющего конусообразное расширение у выходного сечения в объем цилиндра. Кроме того, задача изобретения решена тем, что в форкамерном двигателе с непосредственным впрыском топлива в цилиндр и принудительным зажиганием распыливающее отверстие топливовпрыскивающей форсунки размещено в объеме цилиндра у выходного сечения запального канала с направлением оси распыливающего отверстия в основную камеру сгорания по касательной к окружности, центр которой находится на центральной оси основной камеры сгорания, а радиус равен 2/3 радиуса закругления боковой стенки основной камеры сгорания, выполненной в виде тела вращения в углублении поршня, с возможностью истечения струи распыленного топлива из распыливающего отверстия в основную камеру сгорания в направлении, противоположном направлению вращения воздушного потока, поступающего из впускного канала. Задача изобретения решена также тем, что в форкамерном двигателе с непосредственным впрыском топлива в цилиндр и принудительным зажиганием ось соединительного канала направлена в основнуюThe invention relates to the field of engineering, namely to engine. The objective of the invention is to increase the power density and fuel efficiency of the engine, as well as reducing the amount of toxic combustion products in the exhaust gases. The objective of the invention is solved by the fact that in a pre-chamber engine with direct fuel injection into the cylinder and forced ignition, the prechamber with the cylinder volume is additionally connected via an ignition channel extending into the cylinder volume at the cylinder wall, in the region above the piston crown and having a conical expansion at the output section in the cylinder volume. In addition, the task of the invention is solved by the fact that in a pre-chamber engine with direct fuel injection into the cylinder and forced ignition, the spray hole of the fuel-injection nozzle is located in the cylinder volume at the exit section of the pilot channel with the axis of the spray hole in the main combustion chamber tangentially to a circle whose center located on the central axis of the main combustion chamber, and the radius is 2/3 of the radius of the side wall of the main combustion chamber, made in the form of a body rashchenija in the recess of the piston, with possibility of expiration jet of atomized fuel from the spray holes in the main combustion chamber in a direction opposite to the rotation direction of the air stream entering from the inlet channel. The invention is also solved by the fact that in the pre-chamber engine with direct fuel injection into the cylinder and forced ignition, the axis of the connecting channel is directed to the main
