Abstract: An accessory such as an alternator is mounted to an automobile with a mounting that includes an upper mounting bracket and a lower mounting bracket, these brackets each being connected to the accessory and to the engine. One end of the upper mounting bracket is fixed to a side of the alternator. A length of the upper bracket is provided with an elongated slot and a fastener passing through the slot is fixed to an upper part of the engine such as at a water pump casing, the upper bracket thus being slidable on the fastener to adjust a positioning of the alternator relative to the engine and correspondingly altering a tension in an engine driven accessory drive belt. Because the upper bracket is thus at the accessory inner side, overall engine width is reduced and belt tensioning achieved in more efficient way.

Abstract: An improved lubricating oil passage structure for an engine, which includes: a sub-gallery and a main gallery positioned adjacent to one another in a cylinder block; a head-side oil passage and a journal-side oil passage both being communicated to the main gallery and provided in the cylinder block, in which the head-side oil passage is led to an upper surface of the cylinder block, while the journal-side oil passage is inclined so as be oriented toward a journal portion of a crankshaft; a housing-side oil passage communicated to the journal-side oil passage, the housing-side oil passage being provided in a journal housing section of the cylinder block by the use of a spot facing for a housing bolt, the journal housing section supporting the journal portion; a metal-side oil passage communicated to the housing-side oil passage, the metal-side oil passage being provided in the journal housing section at the rear of a journal metal disposed between the journal portion and the journal housing section; and, a cha
