Description

2. A cylinder head according to claim 1, wherein the circumference of the valve seat is located outside the center of the cylinder, and part of the intake sector is limited. The invention relates to mechanical engineering, namely engine building, and can be used in internal combustion engines. directing or deflecting flow 5 of the working medium.

The aim of the invention is to improve the engine workflow by optimizing the turbulence of the working charge in the cylinder 10

Fig. 1 shows the cylinder head of an internal combustion engine, a longitudinal section J in Fig. 2, section A-A in Fig. 1} in Fig. 3, the same, another embodiment; 15 in FIG. 4 is a section BB in FIG. 3,

The head contains an inlet channel 1.3 of which the seat 2 of the intake valve 3 is installed. The axis 4 of the valve 3 is displaced relative to the axis 5 20 of the cylinder 6. In the output section of the channel 1 before the seat 2 between the walls 7, 8 there are stationary guide vanes 9, B projections onto plane 10 perpendicular to valve axis 25 4 output edges of blades 9 located on one side of line 11 drawn through axis 5, 4 cylinders and valve seats (Fig 2) are located at acute angles, cL, 30

13, 14), conducted through the points corresponding to the ends of the blades 15, The exit edges of the blades 16, located on the other side of the line 11, are perpendicular to the radii 17, 18, 19 and t, d, drawn from the axis 5 of the cylinder 6 to the points , respectively The ends of the blades 16, In the embodiment shown in FIG. 3, the axis 5 of the cylinder 6 is located outside the circumference of the valve seat 2, In this case, part of the sector of the inlet channel 1, bounded in the projection on the plane 10, tangents 20, 21 5 of cylinder 6 (FIG. 3), free from blades 9 and partially throttled by a streamlined protrusion 22 (FIG. 4) forming the jacTb walls of channel 1.

When the engine is operating, the charge coming out of the intake channel 1 (Figs. 2, 3) forms a vortex in the cylinder, which ensures an efficient flow of the working process.

The invention provides improved engine workflow by optimizing charge movement in the cylinder without reducing cylinder filling.
