摘要:
A reciprocating piston internal combustion engine with a cylinder housing and cylinder head consisting of one block, in which the block extends over all cylinders of a cylinder row and the cylinder housing essentially consists of an inner wall and of an outer wall; the inner wall, together with a cylinder head delimits the cylinder space and the inner and outer walls are connected with each other by a cross wall arranged approximately at the height of the cylinder head bottom and extending over the entire block.
摘要:
A cooling water duct system for reciprocating piston internal combustion engines, particularly for those engines with several cylinder heads, whose discharge apertures for the cooling water are connected to a common collecting line arranged outside of the cylinder heads whereby the collecting line is secured at the cylinder block below the cylinder head seal and the cylinder heads are provided with a vent bore at the highest place of their cooling water spaces.
摘要:
A reciprocating piston internal combustion engine with a cylinder head and a cylinder housing consisting of one single block, in which the cylinder housing essentially consists of an inner wall defining together with a cylinder head bottom the cylinder space and of an outer wall separated from the inner wall by a cooling space; the cylinder housing is connected with the crankcase by way of bolts or the like whose center longitudinal axes are disposed in or very close to the center of the outer wall while the outer wall extends up to connecting places disposed above the cylinder head bottom; the cylinder head bottom is supported at these connecting places by way of support walls.
摘要:
A cylinder head of an air-cooled internal combustion engine which is provided with a pressure oil channel for the additional cooling of places in the cylinder head that are particularly subjected to thermal stresses; on the inside of the cylinder head the pressure oil channel passes over into a hollow space whereby cooling ribs are arranged at the inner walls of the hollow space.
