Abstract

PURPOSE:To perform cooling of a part between valves without forming a drilled hole by partitioning the cooling water jacket of a cylinder head into upper and lower chambers by means of a partition plate, communicating the lower part of the partition plate to the cylinder block side, forming an outlet in the upper part thereof, and forming upper and lower through-holes between two exhaust gas ports. CONSTITUTION:A cooling water jacket 3 is formed in a cylinder block 1 and a cylinder head 4 is fastened against the cylinder block. The cooling water jacket 11 of the cylinder head 4 is partitioned into lower and upper cooling water jackets 11a and 11b by means of a partition plate 12. Cooling water is introduced from the cooling water jacket 3 through a through-hole 13 and is caused to flow out through the upper cooling water jacket 11b. A cooling water pass hole 14 is formed in a spot where the partition plate 12 is extended through a sleeve 5 and in a portion between exhaust gas ports 8 and 9 and cause intercommunication of the cooling water jackets 11a and 11b. This constitution causes positive cooling of parts between intake air ports 6, 7 and exhaust gas ports 8, 9, respectively.

2. Description of the Related Art In recent internal combustion engines, in order to improve the output and the like, one cylinder is provided with two intake valves and two exhaust valves, and a four-valve type is provided. However, in this four-valve internal combustion engine, two intake ports each having an intake valve and two exhaust ports each having an exhaust valve are provided close to each other, so that the valves of the cylinder head are mutually connected. Since the temperature in the space between the exhaust valves becomes higher, especially in the space between the two exhaust valves, heat cracks occur in the parts of the cylinder head between the valves, and the heat in the cylinder head Thermal adverse effects such as large distortion occur.

However, it is necessary to form a drill hole for flowing the cooling water in the portion between the valves so that each drill hole is formed from the outer side surface of the cylinder head.
It has to be drilled using a fairly long drill tool, which not only requires a great deal of work,
Since it is necessary to close the opening of the drill hole to the outer surface of the cylinder head, there is a problem that the manufacturing cost is significantly increased.

Moreover, since the holes between the valves must be formed with a considerable thickness in order to form the drill holes in the parts between the valves, the weight of the cylinder head is reduced. It is considerably improved, and furthermore, the layout of each of the four valves will be limited by drilling holes from the outer surface of the cylinder head with respect to the parts between these valves. There was also a problem that the layout of each valve could not be set arbitrarily.
