    摘要: A connecting rod as a shaft clamping member includes a rod member and cap, each of which has mating faces at circumferentially opposite ends of a semi-circular recess and which are fastened to each other by bolts by matching the opposed mating faces to each other to define a crank pin hole by the two semi-circular recesses. The rod member and the cap are forgings formed from an aluminum alloy and simultaneously produced by forging powder preforms of the rod member and cap in a cavity having the desired shape of the connecting rod. After forging, the opposed mating faces have an infinite number of recesses and projections which are formed from the flow of the material during the forging and which are in a matched and fitted relation to each other. Thus, any misalignment between and in a direction parallel to the mating faces can be prevented to avoid the generation of a situation that only the rod member receives a stress. This achieves a prolongation in the life of the connecting rod of the aluminum alloy. The composition of the most desirable aluminum alloy includes, by weight, 7% .ltoreq.Fe

    摘要: In a powder forging process, a heated green compact is placed in a stationary die and subjected to a press-forging carried out mainly to reduce the thickness thereof by cooperation of the stationary die with a movable die. The press-forging is performed at two pressing steps. After placement of the green compact into the concave molding portion of the stationary die, the pressing step were carried out. Thus, it is possible to produce a forged product having a high strength and a high toughness. A heated heat insulator also may be placed in the stationary die to provide a temperature-retaining effect to the green compact before and during pressing.

    摘要: A powder preform of aluminum alloy powder is subjected to a heating treatment and then to a compacting and hardening process under a pressure to produce a structural member of aluminum alloy. The aluminum alloy powder used is one having a non-equilibrium phase which shows a calorific value C in a range of C.gtoreq.10 J/g at a temperature-increasing rate of 20 K./min in a differential scanning calorimetry. In the heating treatment, the average temperature-rising rate R.sub.2 from a heat-generation starting temperature Tx (K.) of the aluminum alloy powder to Tx+A (wherein A.gtoreq.30 K.) is R.sub.2 .ltoreq.60 K./min. Thus, the change of the non-equilibrium phase in the powder preform is uniformly performed. In addition, the average temperature-increasing rate R.sub.4 from a processing temperature Tw (K.-B) in the compacting and hardening process to Tw (wherein B.gtoreq.30 K., and Tw-B>Tx+A) is R.sub.4 .gtoreq.60 K./min. Thus, the oxidation of the powder preform is reliably prevented.

    摘要: A heat- and abrasion-resistant aluminum alloy having a grain size of the matrix of .alpha.-aluminum in the alloy not more than 1,000 nm; a grain size of an intermetallic compounds contained in the alloy of not more than 500 nm; and 0.5 to 20% by volume of ceramic particles in the range of 1.5 to 10 .mu.m in particle size and dispersed in the alloy. By this composition, the stress concentration due to the ceramic particles is reduced. Furthermore, because the powders bind well with each other, the heat resistance and abrasion resistance are compatibly improved without decreasing toughness and ductility.

    摘要: A Rankine cycle system having a working medium circulation circuit (110) that includes an evaporator (112), an expander (113), a condenser (114), and a feed pump (115) is provided in which a mixture of oil for lubricating the expander (113) and water, which is a working medium and has become mixed with the oil, is supplied to coalescer type water separating means (118), thus separating the water from the oil. The oil from which water has been separated in water separating means (118) is returned to the expander (113), and the water separated from the oil is returned to the working medium circulation circuit (110). It is thus unnecessary to replenish the working medium circulation circuit (110) with water or replenish the expander (113) with oil.

    摘要: A Rankine cycle system includes a first Rankine cycle (2A) operated by a first working medium and a second Rankine cycle (2B) operated by a second working medium. The first Rankine cycle (2A) is constituted from an evaporator (3A), an expander (4), a condenser (5A) and a supply pump (6A), and the second Rankine cycle (2B) is constituted from an evaporator (3B), the expander (4), a condenser (5B) and a supply pump (6c). The evaporator (3A) in the first Rankine cycle (2A) and the evaporator (3B) in the second Rankine cycle (2B) are disposed at locations upstream and downstream of an exhaust emission control device (8) mounted in an exhaust passage (7) for the internal combustion engine (1). The first working medium has a boiling point higher than that of the second working medium, and the capacity of the pump (6A) in at least the first Rankine cycle (2A) is variable. Thus, the efficiency of recovery of a waste heat from the internal combustion engine by the Rankine cycle system can be enhanced to the maximum, and the activation of the exhaust emission control device can be promoted.

    摘要: In an internal combustion engine, a combustion chamber is provided in a cylinder head on one side of a partition wall, and a heat-insulating layer is provided in the cylinder head on the other side of the partition wall. Cooling passages are provided in a plurality of regions provided with different heat loads in the partition wall, respectively. The flow rate of a cooling medium is set, so that the flow rate in the cooling passage existing in the region of the larger heat load is larger than that in the cooling passage existing in the region of the smaller heat load. Thus, the temperature of an exhaust gas can be maintained at a high level by maintaining the combustion chamber at a high temperature.
