摘要： A spacer (14) arranged inside a water jacket (13) which is formed to surround peripheries of cylinder bores (12a) in a cylinder block (11) of an internal combustion engine includes support legs (14e, 14f, 14g, 14h) extending in an up-and-down direction from a spacer main body part (14a) which partitions the water jacket (13) into an upper and lower cooling water passages. The support legs (14e, 14f, 14g, 14h) are disposed in opposite end portions in a cylinder row line (L1) direction, where the temperatures of the cylinder bores (L1) tend to be lower. Accordingly, even if the flow of cooling water is more or less inhibited by the support legs (14e, 14f, 14g, 14h) and the cooling effect deteriorates, it is possible to prevent the temperatures of the respective cylinder bores (12a) from becoming different by suppressing the influence to a minimum.

摘要： The present invention relates to an insert (10, 110) for a cylinder sleeve (20, 120, 220) or for a cylinder (222) of an internal combustion engine (30, 130, 230) for reducing the diameter of the cylinder sleeve (20, 120, 220) or of the cylinder in the region (21, 221) of the upper dead center position of a piston (33, 233) guided into the cylinder sleeve (20, 120, 220) or the cylinder. According to the invention, the insert (10, 110) is in the form of an open, pretensioned ring with a ring joint (11, 111), and is held radially by its outwards acting radial forces and axially by a recess (121; 221) in the cylinder sleeve (20, 120, 220) or the cylinder (222) in such a way that the radial surface pressure around the circumference is approximately constant, wherein the ratio of the ring wall thickness (d) to the internal diameter (D) of the cylinder sleeve or the cylinder amounts to between 0.001 and 0.02.

摘要： A water jacket spacer is inserted into a water jacket. The water jacket spacer comprises an expansion member, a plate-shaped holder to which the expansion member is fixed, and a leaf spring that abuts the inner wall of the water jacket. The leaf spring projects from a face on the holder on the side opposite of the expansion member. The holder curves to match the shape of the water jacket. The position of the water jacket spacer in the water jacket is maintained by the biasing force of the leaf spring.

摘要： A communication unit (200) for use in a communication system is provided which includes a hopping mechanism (114, 144) which hops communication frames over a plurality of carrier frequencies according to a predetermined hopping pattern. At least one of the communication frames preferably includes a synchronization channel time slot having data bits from which the predetermined hopping pattern may be derived. In addition, a communication unit (100) is provided which includes a signal acquisition mechanism (142) for initially acquiring a predetermined hopping pattern that specifies the sequence over which hop frames are hopped over a plurality of carrier frequencies. Also, this communication unit (100) includes a hopping mechanism (134, 144) for hopping receiving frequency according to the predetermined hopping pattern such that a control channel may be detected. In an alternative embodiment, either communication unit may derive the predetermined hopping pattern from detected global position satellite information (149).

摘要： An internal combustion engine has a cylinder block that has one or more cylinders, hollow-cylindrical cylinder liners that are placed in the cylinders, a piston that reciprocates in each cylinder liner and whose outer peripheral surface between the piston head and the uppermost ring groove forms a top land section, and a liner installation ring that forms in a cylinder an annular step section protruding to the inner periphery side of the cylinder liner and that is installed on either the cylinder block or the cylinder liner with the lower face of the liner installation ring facing the uppermost section of the cylinder liner. The liner installation ring is installed so as to correspond to a position that is the upper end position of the top land section when the piston has reached the top dead center, and the length of the inward protrusion of the liner installation ring from the inner periphery of each cylinder liner is set not less than 0.05 mm and not more than 0.5 mm.
