Abstract: A method and a device for removing the chips of a connecting rod. The large end part of the connecting rod is placed on the step part of a pedestal, and the small end part thereof is placed on a pedestal formed of a vibration damping material. An air vibrator is energized to continuously supply compressed air to vibrate the large end part together with the pedestal until the vibrated large end part is brought into contact with a contact plate member. When chips fall from the rod body and the cap part of the connecting rod, the chips are collected to a transparent collection bag through a suction hose by a dust collector. The operations above are performed in a sound isolation box closed by a cover member. Then, the chips are separated from the broken-out sections of the rod body and the cap part by using, for example, a brush.

Abstract: The Internal-Combustion Engine is set forth, in which when in use there is no lateral component of the force on the piston which is taken up by the slider rolling by the bearings. As a result of this the cylinder compression is improved, power losses on friction are reduced and wear out of the cylinder is decreased. Also due to the absence of the lateral component of the force on the piston, the latter can be made in a relieved version, e.g. without a skirt and with two compressing rings in one groove.

Abstract translation: 内燃机的特征在于，在使用中，在活塞上没有由滑块滚动而被轴承卷绕的力的横向分量。 其结果是提高了气缸的压缩性，降低了摩擦力的功率损失，减少了汽缸的磨损。 而且由于在活塞上不存在力的侧向分量，所以后者可以以缓解的方式制成，例如， 没有裙子，在一个槽中有两个压缩环。

Abstract: A connecting rod includes a rod main body, a small end located at one end of the rod main body and a big end located at another end of the rod main body, the big end including a curved section which is curved so as to become narrower toward the rod main body. The big end is formed of a metal material whose composition is different from that of the rod main body, and is bonded to the rod main body. A joint between the big end and the rod main body is located closer to the small end than is an end of the curved section facing the rod main body.

Abstract: A connecting rod and methods for making the same are disclosed. A method of making a connecting rod may include joining a first connecting rod blank and a second connecting rod blank together. The first connecting rod blank includes a first material, while the second connecting rod blank includes a second material different from the first material. The first and second connecting rod blanks have an interface between the piston pin and crankshaft ends.

Abstract: A member produced by powder forging which retains machinability and improved fatigue strength without having an increased hardness and can retain self conformability after fracture splitting; a powder mixture for powder forging; a process for producing a member by powder forging; and a fracture splitting connecting rod obtained from the member produced by powder forging. The member produced by powder forging is one obtained by preforming a powder mixture, subsequently sintering the preform, and forging the resultant sintered preform at a high temperature. The free-copper proportion in the sintered preform at the time when the forging is started is 10% or lower, and the member obtained through the forging has a composition containing, in terms of mass %, 0.2-0.4% C, 3-5% Cu, and up to 0.4% Mn (excluding 0), the remainder being iron and incidental impurities, and has a ferrite content of 40-90%.
