    Cylinder head surface cooling bores 19 (Fig. 1) and valve-seat cooling ducts 32 (Fig. 3) are separate and independently supplied with coolant. In operation, the cooling temperature of the cylinder head coolant is 60 DEG C, whereas the temperature of the valve seat coolant is more than 110 DEG C. Only the exhaust valve seats need be cooled, or both the exhaust valve and the intake valve seats can be cooled. <IMAGE>

    39 According to another embodiment of the invention, the bottom contour comprises a group of channel-cooling zones of the head, each of which is limited by two radial planes of two adjacent valves intersecting on the longitudinal axis of the cylinder, each group of cooling channels being formed by one radial internal channel and several connected to him, the external channels located on the periphery of the head in the radial direction. Pr | This external channels communicated with the channels of the cooling sleeves using channels made in the lower part of the head. Fig. 1 shows an axial section through a divided into upper and lower parts of the cylinder head and the upper part of the cylinder liner in figure 2 - section AA, in figure 1; on fig.Z - section bb in fig.2; Fig. 4 is a section B-B in Fig. 3. A cylinder head consists of a top-25 lower lower part 1, lower part 2 fastened together, with a cylinder 3, a working piston guiding piston (not shown) by means of screws 4 on a cylinder block not shown . Two recesses 5 and 6 in the upper and lower parts of the head pass parallel to the cylinder liner axis 3, and recesses 5 contain an exhaust valve 7 and recesses 6 - an inlet valve 8. The upper part 1 of the cylinder head has gas channels 9 and a chamber 10, supplying coolant to the channels 9 ,, as well as the notch 11 ,. located coaxially to the cylinder liner 3, with the sleeve 12, passing into the lower part 2, and serving as a housing for an uncoupled fuel injector. Between the upper and lower parts 1 and 2 of the space surrounding the gap, sleeve 12, sealing sleeve 13) allowing the free flow of the bottom head cooling channel 14 and 15 through the cooling medium channels 1b to the chamber 10, and preventing the output from passing through inoBepxHOCTbi. between parts t and 2. Channels 14 and 15 for cooling the bottom of the cylinder head are distributed in a plane in the vicinity of the combustion chamber 17 of the bottom surface 18 of the cylinder head (Fig. 2). This 1 plane lies under the plane in which the cooling channels of the valve seats are located. The cooling of the bottom is divided into four zones, each of which is limited by two radial planes intersecting on the longitudinal axis 19 of the cylinder. Each such cooling zone is assigned a group of cooling channels Ik and 15. Each of these groups consists of a radial internal channel I and three communicating with it, located along the periphery in the radial direction of the external channels 15 closed to the outside by threaded plugs 20, Internal channels lA through connecting channels 16 communicating with those provided, on the one hand, between the sleeve 12 and the lower part 2, an annular channel 21, which in turn communicates with the chamber 10. The external channels 15 communicate with the cooling channels 22 of the relief channel 23 and casing 24 made of the head. The casing and the lower part of the head are made in one stage, and the casing 24 perceives the tensile forces of the sleeve 3 of the cylinder. The channels 23 are closed down by means of threaded plugs 25 and through channel 26 and radial c-rings 27 communicate with cooling channels 22 made in the cylinder liner 3. 29. Along the outer circumference of each ring of the 28-valve seat between the latter and the limiting surface of the recess, there is a lower annular bore 30 facing the seating surface 29 of the valve and the upper annular channel 31, which is The canal with the channel 30 through the recesses 32. The inlet channel 33 leads from the periphery surface of the lower part 2 of the cylinder liner to the lower annular channel 30 and the outlet channel 34 from the upper annular channel to the outside. By completely separating the cooling cycle of the channel seats from the cooling cycle of the head bottom, it is possible to calculate them independently of each other. The cooling temperature and the flow rate of the cooling medium can be selected as desired. In addition, relatively small amounts of cooling means are required to cool the valve seat. In the head cooling cycle, the cooling medium flows as follows: from the cooling channels 22 of the cylinder liner 3 through the annular channel 26, the radial channels 27 and the channels 23. Next, the cooling medium flows through the external channels 15 through the internal channels J4, while cooling , the bottom of the head, after which it passes through the channels 16 and the ring channel 21 enters 10, the cooling medium in the channels for cooling the bottoms of the cylinder head has a temperature of 120 to 130 ° C and the flow rate through the internal channels is more than 1 m / s ... saddle cooling cycle The means flows through the inlet channel 33 into the lower channel 30 and at the same time cools the corresponding surface 29, then through the recesses 32 - 3 the upper annular channel 3 and through the outlet channel 3 to the peripheral surface of the lower part 2 of the cylinder head. The channels 33 and 3 at their outer ends are connected with unsupported supply and discharge lines to which they are connected
    SOS. In the described embodiments of cooling;, the upper part 1 is preferably made of gray iron or nodular cast iron, and the lower part 2 is made of steel or cast steel. Casing 2 can be made as a separate part, from gray cast iron or steel casting.
