摘要： PROBLEM TO BE SOLVED: To provide a lubricating device of a supercharger capable of stably preventing oil leakage regardless of the operation state of the supercharger.
SOLUTION: The lubricating device 1A comprises a pair of oil seals 21, 22 for preventing oil leakage between a compressor chamber 6 and a bearing chamber 7 mounted with a distance in the axial Ax direction of a rotation shaft 4 on a partition wall 9 formed for sectioning the compressor chamber 6 of a turbocharger 2 and the bearing chamber 7 to receive oil supply and having a through-hole 9a for inserting the rotation shaft 4. A communication path 23 is provided for connecting a space S formed between the outer circumferential surface of the rotation shaft 4 and the inner circumferential surface of the through-hole 9a between the pair of the oil seals 21, 22, with an oil returning path 10 for returning the oil supplied to the bearing chamber 7 to an oil pan 11.

摘要： PROBLEM TO BE SOLVED: To properly raise the temperature of a catalyst in a twin turbo-system. SOLUTION: This control device for an internal combustion engine with superchargers operates a second supercharger by regulating a supercharging pressure using an exhaust gas changeover valve when the temperature of the catalyst is equal to or less than a predetermined one in an operating range in which only a first supercharger is to be operated and the supercharging pressure must be regulated using an exhaust gas bypass valve, and supplies a supercharging air by the operation of the second supercharger to the upstream side of the compressor of the first supercharger. The intake air heated by the operation of the second supercharger is supplied to the upstream side of the compressor of the first supercharger by operating the second supercharger using the exhaust energy which is disposed off by a Waste gate. Consequently, the temperature of the exhaust gas can be raised by raising the temperature of the intake air, and the temperature of the catalyst can be raised. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：适当提高双涡轮增压系统中催化剂的温度。解决方案：用于具有增压器的内燃机的控制装置通过使用排气切换阀调节增压压力来操作第二增压器，当催化剂的温度等于或小于预定值时，在工作范围内仅使用第一增压器并且使用废气旁通阀来调节增压压力，并且通过第二增压器的操作将增压空气提供给第一增压器的压缩机的上游侧。通过第二增压器的运转而加热的进气通过使用废弃物排出的排气能量操作第二增压器而被供给到第一增压器的压缩机的上游侧。因此，可以通过提高进气的温度来提高废气的温度，并且可以提高催化剂的温度。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a technology for avoiding a bad effect in the case of opening a low-pressure exhaust side bypass valve in a multi-stage supercharging system for internal combustion engine. SOLUTION: This multi-stage supercharging system for internal combustion engine includes: a high-pressure turbocharger; a low-pressure turbocharger; a low-pressure exhaust side bypass passage bypassing a low-pressure turbine; and a low-pressure exhaust side bypass valve for controlling the exhaust quantity flowing in the low-pressure side bypass passage. In the case of requiring catalyst warm-up (S101-YES) and opening the low-pressure exhaust side bypass valve, when a predetermined condition relative to reduction of the number of revolution of a low-pressure compressor is satisfied (S102-NO), the low-pressure exhaust side bypass valve is closed (S104).
