Abstract: There are provided a highly durable and efficient refrigerating apparatus and a lubricating oil composition that uses an HFC type refrigerant and is still free from the problem of thermal hydrolysis of polyol-ester type oil and resulting generation of carboxylic acid and sludge so that the refrigerating apparatus and the lubricating oil composition may be used stably for a prolonged period of time. A lubricating oil composition according to the invention comprises as base oil components a polyol-ester type oil formed by reacting specific polyhydric alcohol with a fatty acid, to which tricresylphosphate and epoxy compound comprising glycidyl ether or carbodiimide are added at respective specific rates. A refrigerating apparatus according to the invention uses such a lubricating oil composition as refrigerator oil and comprises a sealed electric driving compressor whose sliding members are made of a material selected from iron type materials, composite materials of aluminum and carbon, iron type materials surface-treated with chromium nitride and ceramic materials.

Abstract: Present day diesel engines having aluminum piston assemblies are limited to combustion chamber pressures of approximately 12,410 kPa (1,800 psi) whereas the desire is the increase such pressures up to the 15,170 kPa (2,200 psi) range. To reach such levels the instant piston assembly includes a steel piston member having an upper cylindrical portion defining a top surface, a depending tubular wall and an annular cooling recess having one or more machined surfaces or revolution about a central axis. The cooling recess is located beneath the top surface and juxtaposed to the top ring groove for removing heat away therefrom in use. The piston member is preferably forged and subsequently machined to precisely controllable dimensions. Moreover, the piston assembly is preferably of the articulated type and includes a forged aluminum piston skirt connected to the piston member through a common wrist pin.

Abstract: PROBLEMS
Local stress concentration caused by rotational moment transmitted from a crankshaft is eased.
MEANS FOR SOLVING PROBLEMS
A crankshaft (6) and an mounting hole (5) have two main circular arc parts (11, 21) on the same circle; and two connecting parts (12, 22) for connecting the adjacent main circular arc parts (11, 21), and have a cross-sectional shape in which the connecting parts (12, 22) facing each other are substantially parallel. The connecting parts (22) of the mounting hole (5) are formed in the shape of a large circular arc which projects inward. The torque of the crankshaft (6) is transmitted to the mounting hole (5) in a state where the connecting parts (12) of the crankshaft (6) and the connecting parts (22) of the mounting hole (5) which are formed in the shape of a large circular arc come into line contact with each other; therefore, the value of any local stress generated in the mounting hole (5) can be reduced.

Abstract: A piston (20) for an internal combustion engine includes an upper crown (22) and a lower crown (24) that are each fabricated using a same strong material, such as steel and fastened together using a plurality of fasteners (50). The piston (20) provides increased strength resulting in improved design flexibility and smaller sized engines that produce the same amount of power. Piston ring grooves (100, 102, 104) are also provided in either one or both of the upper and lower crowns (22, 24) which control piston combustion height. A deeper combustion bowl (72) is also available with the piston (20).
