Cylinder block

摘要

A one-piece cylinder block for a water-cooled internal combustion engine with two rows of cylinders in a V-arrangement has a longitudinal duct for supplying cooling water. The block is preferably made by a diecasting process. The longitudinal duct is connected to the coolant spaces of the cylinders which are located between a cylinder sleeve and an outer jacket surrounding the latter. The longitudinal duct is disposed between the rows of cylinders in the cylinder block and at least one opening is provided in the region of the coolant spaces for each cylinder. These openings are cast in the casing walls of the cylinder block. Since they are disposed directly adjacent the longitudinal duct, they extend essentially radially to the cylinders.
