Abstract: Disclosed herein is an exhaust insulator structure for a multi-cylinder engine of a vehicle. The structure includes an exhaust manifold, an exhaust gas purifier, and a heat insulator. The engine is able to switch its mode of operation from an all-cylinder operation in which all of four cylinders thereof are activated to a cylinder-cutoff operation in which two of the four cylinders are deactivated to serve as idle cylinders and the other two cylinders are activated to serve as active cylinders, or vice versa. The exhaust manifold includes: idle-cylinder-connected branched exhaust piping communicating with the idle cylinders; and active-cylinder-connected branched exhaust piping communicating with the active cylinders. A portion of the heat insulator facing the active-cylinder-connected branched exhaust piping has an opening that lets air blowing against the vehicle traveling into the heat insulator.

Abstract: A management server refers to a server information management DB that stores therein information on a plurality of virtual servers generated from a plurality of virtual images and information on software that operates on the virtual servers, and selects other virtual server in conjunction with a particular virtual server from the plurality of virtual servers based on information on the particular virtual server generated from a predetermined virtual image and information on software that operates on the particular virtual server. The management server extracts a patch to be applied to the particular virtual server based on patches applied to the other virtual server.

Abstract: A configuration management apparatus acquires a value of a configuration information item from a collection target apparatus to thereby manage the configuration of the collection target apparatus. To that end, the configuration management apparatus includes a determining unit and an acquiring unit. The determining unit determines an acquisition timing of acquiring the configuration information item based on at least one of reference frequency of the configuration information item being referred to, update frequency of the value of the configuration information item being updated, and load on the collection target apparatus in such a manner as to control the load on the collection target apparatus. The acquiring unit acquires the configuration information item from the collection target apparatus at the determined acquisition timing through cooperation with the collection target apparatus.

Abstract: An administration server executes a process of first acquiring first resource information on a resource used by a function executed on a server to which a patch is to be applied. Then, the administration server executes a process of second acquiring second resource information on a resource accessed by the patch when the patch is executed. Thereafter, based on the first resource information acquired at the first acquiring and the second resource information acquired at the second acquiring, the administration server executes a process of determining whether to apply the patch.

Abstract: Two turbochargers are arranged vertically near a one side of a crank-shaft direction at a one-side face of an engine body so that the large-size turbocharger is located above the small-sized turbocharger, and an exhaust-gas purification device is arranged an open space made on the other side of the crank-shaft direction so that its exhaust inlet is located above and its outlet is located below. Accordingly, the turbochargers and the exhaust-gas purification device can be arranged compactly and the layout of some devices around the engine can be facilitated.

Abstract: A skirt section of the cylinder block is shortened to the height of the rotational center of the crank shaft. To the bottom end of the skirt section is the lower cylinder block whose bottom end is coupled to the oil pan. The inner space of the lower cylinder block section is divided by plural partition walls extending transversely between the side walls of the lower cylinder block section. A bearing cap supporting the crank shaft has a boss section projecting transversely and a threaded hole is formed in the boss section. Further, the bottom end of the bearing cap has a threaded hole having an opening facing bottom. The lower cylinder block section is further provided at its side wall with a hole through which the side portion of the bearing cap is connected to the side wall of the lower cylinder block section. The bottom end of the bearing cap is connected to the side wall of the lower cylinder block section.

Abstract: A cylinder block including an upper block, a crankshaft and a lower block, has a plurality of bearing caps secured to the upper block so as to support the crankshaft for rotation. A generally rectangularly-shaped lower block casing is provided with a first reinforcing rib, located below each bearing cap and extending upright so as to connect opposite side walls of the casing, and a second reinforcing rib, extending from a fitting bracket. A transmission casing is fitted to the cylinder block through the fitting bracket. The second reinforcing rib terminates approximately below one of the bearing caps. The first reinforcing rib associated with the one of the bearing caps is separated from the bearing caps. The first reinforcing ribs are provided with structural stiffnesses such that a first reinforcing rib which is farther away from the one of the bearing caps than another first reinforcing rib has a lower structural stiffness than the other first reinforcing rib.

Abstract: An oil pan for a vehicle engine is cast to have shallow and deepened bottom oil pan sections and an integral fitting flange to which a transmission case is attached. The fitting flange is formed with bosses for receiving bolts to tightly attach the oil pan to an engine block of the vehicle engine. First or outer reinforcing ribs extend along the center line of the bosses. Second or back reinforcing ribs are arranged correspondingly to the outer reinforcing ribs. Bolts pass through the bosses and tighten the oil pan to the bottom of the cylinder block of the vehicle engine.
