摘要： PROBLEM TO BE SOLVED: To reduce friction loss, and to prevent deterioration of rolling service life due to abrasion by preventing an edge load.
SOLUTION: In a rocker arm 12 of the roller rocker arm type valve gear 10, a roller 24 is turnably supported by a roller pin 26 via a plurality of needle rollers 22. A diametrally enlarged part 30 with a diameter enlarging from a roller 24 width direction center part side toward both end part sides is formed on roller 24 width direction both ends in an inner circumferential face of the roller 24. When there is an error of alignment during manufacture, or due to operating conditions or the like, and an outer side roller 24 is tilted by abutting with a cam, edge loads tend to occur in respective axial (a roller 24 width direction) end parts of the inner circumferential face of the roller 24, and the plurality of needle rollers 22. But, since the diametrally enlarged part 30 is formed on the roller 24, even if the roller 24 is tilted, the edge loads do not increase in the axial end parts of the inner circumferential face of the roller 24, and the plurality of needle rollers 22.

摘要： PROBLEM TO BE SOLVED: To provide a roller rocker arm for maintaining fluid lubrication and reducing friction loss even under low speed and high oil temperature operation condition wherein an oil film between sliding surfaces becomes thin.
SOLUTION: An inside roller 22 and an outside roller 24 are coaxially and rotatably supported on the rocker arm 12 and are arranged in a double ring shape. A crowning surface portion 30 and a chamfer 32 serving as inclined surfaces are formed at opposite ends in a width direction of an outer peripheral surface of the inside roller 22. Because of the crowning surface portion 30 and the chamfer 32 formed on the outer peripheral surface of the inside roller 22, even when the outside roller 24 is tilted, an edge load does not increase at axial ends of an inner peripheral surface of the outside roller 24 and the outer peripheral surface of the inside roller 22 and oil film breakage is not caused. Wear resistance which is an advantage of a plain bearing is kept high and fluid lubrication is maintained even under the low speed and high oil temperature operation condition so that an increase of friction loss can be prevented.

摘要翻译：要解决的问题：即使在滑动表面之间的油膜变薄的低速和高油温操作条件下，也提供一种用于保持流体润滑并减少摩擦损失的滚子摇臂。解决方案：内侧辊22和外侧辊24同轴并可旋转地支撑在摇臂12上，并配置成双环状。在内侧辊22的外周面的宽度方向的相对端形成有作为倾斜面的凸面部30和倒角32.由于凸面部30和倒角32形成在外周面上即使在外侧辊24倾斜的情况下，外侧辊24的内周面和内侧辊22的外周面的轴向端部的边缘负荷也不会增加，油膜破损也不会造成的。作为滑动轴承的优点的耐磨性保持高，并且即使在低速和高油温操作条件下也保持流体润滑，从而可以防止摩擦损失的增加。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a cylinder lubricating device capable of providing good lubricating performance in a cylinder of an engine, especially a diesel engine using fuel as lubricating oil.
SOLUTION: The cylinder lubrication device 20 is provided with a high pressure fuel injection valve 19 injecting fuel into the cylinder 21 of the engine 1 at high pressure, and a low pressure fuel injection valve 24 injecting fuel into the cylinder at low pressure. The low pressure fuel injection valve 24 is supplied with fuel by a lubrication pump supplying fuel as lubricating oil to an engine lubrication system such as a periphery of a cylinder head and a periphery of a crankshaft. Injected fuel can be adhered on a cylinder liner 22 without evaporating the same by injecting fuel into the cylinder 21 at low pressure. Consequently, fuel evaporates on the cylinder liner 22 to avoid getting into a dry condition to reduce friction.

摘要： PROBLEM TO BE SOLVED: To provide a piston ring which exerts characteristics corresponding to a light oil lubrication type diesel engine that uses a fuel such as light oil as a lubricant. SOLUTION: A piston ring (1) comprises an expander (6) on the inner peripheral side of a piston ring body (5). The expander (6) is formed by incorporating a circumferential length adjusting mechanism (8) in a coil spring (7) formed in a ring. The circumferential length adjusting mechanism (8) comprises a rod (9) of which a flange (9a) is provided at the central part, and a left side support part (10a) and right side support part (10b) for supporting the rod (9). A shape memory member (11) of shape memory alloy which is formed in coil is arranged between the left side support part (10a) and the flange (9a). A bias spring (12) is arranged between the right side support part (10b) and the flange (9a). Thus, the pressurizing force of the expander(6) in radial direction against the piston ring body (5) is smaller in a high temperature state than in a low temperature state.
