专利摘要:
A diesel cycle internal combustion engine having at least one cylinder with coplanar induction and exhaust valves and a precombustion chamber, in which the cylinder head is formed with a recess defining a combustion chamber with a projection on the crown of the piston, both the recess and the projection having a triangular cross section with respective upper surfaces being inclined at different angles from one another with respect to the longitudinal axis of the cylinder and respective side surfaces being inclined at substantially the same angle as one another with respect to the longitudinal axis of the cylinder. 公开号:SU1075992A3 申请号:SU782651748 申请日:1978-08-15 公开日:1984-02-23 发明作者:Бурджо Антонио 申请人:Фиат Ауто Сочиета Пер Ациони (Фирма); IPC主号:
专利说明:
The invention relates to mechanical engineering, namely engine building, in particular, to designs of internal combustion engines with prechambers. Diesel cycle internal combustion engines are known that contain a block of cylinders whose axes are located in the same plane, a head housed in the head of the ancestor of the measure, inlet and exhaust valves and a main combustion chamber whose main part is made with a triangle-shaped cross section in the cylinder head, provided with upper and lateral surfaces, the upper surface is orthogonal to the valve stem and formed by valve sockets, and the lower surface is bounded by the upper surface of the protrusion and the bottom of the piston, о.bred in the direction of the upper surface of the groove in the head, located at an angle to it and mated with the flat surface of the peripheral part located on the side remote from the prechamber, the flat surface of the peripheral part of the bottom, adjacent to the bottom surface of the cylinder heads, the surfaces are orthogonal to the axis of the cylinder, and the side surface of the main combustion chamber is located near the side bevel of the protrusion on the bottom of the piston at the position of the piston at the upper dead point And. However, the known internal combustion engines with a prechamber placed to the side of the main combustion chamber do not provide a homogeneous combustion of the mixture in connection with non-optimal placement, the shape of the precumulus and, therefore, turbulence of the fuel when exiting the prechamber into the main combustion chamber. The aim of the invention is to optimize the shape of the combustion chamber by ensuring complete and rapid combustion. The goal is achieved by the fact that the upper surface of the groove of the axle plate is 1215 ° with the lower surface of the cylinder head and with the upper surface of the protrusion on the bottom of the piston 2-10, and the angle between the longitudinal axis of the cylinders and the axis of the precamera is equal. The drawing shows the internal combustion engine, the cut. The engine contains a block 1 of cylinders 2, the longitudinal axes 3 of which are located in one plane, the head 4 of cylinders 2, placed in head 4, prechamber 5 with its axis b, main combustion chamber 7, the main part of which is made with a triangular cross-section bounded the side surface 8 of the groove and the top surface 9 of the groove in the head 4, intake and exhaust valves (not shown, the axis 10 which is parallel to each other, and perpendicular to the upper surface 9 of the groove formed by the valve slots 11. Bottom surface The groove is bounded by the upper bore 12 of the protrusion 13 on the bottom 14 of the piston 15 facing the top surface 9 of the groove of the head 4. The protrusion 13 on the bottom 14 of the piston 15 is mated with the flat surface of the peripheral part of the bottom 14 adjacent to the bottom surface 16 of the cylinder head 2. The bottom surface 16 of the head 4 and the flat surface of the bottom 14 are perpendicular to the axis of the m 3 cylinder 2, the side surface 8 of the groove is part of the side surface: the main combustion chamber 7, located in From the side bevel 17 of the protrusion 13 on the bottom 14 of the piston 15, the angle between the top surface 12 of the protrusion 13 and the bottom of the piston 15 and the top surface 9 of the groove is 2-10, the angle between the longitudinal axis 3 of the cylinders 2 and the axis 6 of the precamera 5 is 20i5 and the angle between the top surface 12 of the groove and the bottom surface 16 of the head 4 is made equal to 1215. When the engine is running, fuel is injected into the pre-chamber 5. After its ignition, the combustion products through the channel in the pre-chamber 5 enter the cylinder 2 of the engine. The pre-chamber channel is located on the side surface 18 of the main combustion chamber 7 near the side bevel 17. The optimal shape of the combustion chamber ensures complete and rapid combustion of the fuel.
