    Abstract: PROBLEM TO BE SOLVED: To improve a structure of a reciprocating internal combustion engine by a means simple and advantageous in cost so as to achieve good total efficiency and a stable operation condition. SOLUTION: In an engine provided with at least one exhaust gas recirculation device 16 provided with at least one cylinder 2 capable of being connected to a charged air distribution pipe 4 and an exhaust gas collecting pipe 6, at least one exhaust gas turbocharger 7 driven by exhaust gas from the exhaust gas collecting pipe 6 and compressing charged air supplied to the charged air distribution pipe 4, and a compressor 20 mixing exhaust gas partial quantity branched out of exhaust gas separating from the exhaust gas collecting pipe 6 to charged air in a downstream of the exhaust gas turbocharger 7 and pumping exhaust gas partial quantity mixed to charged air, since the compressor 20 of the exhaust gas recirculation device 16 can be driven by a turbine 19 energized by drive air branched out of charged air compressed by the exhaust gas turbocharger 7 as partial air quantity and heated by exhaust gas partial quantity while exhaust gas partial quantity to be recirculated is simultaneously cooled, good total efficiency and stable operation condition are achieved.

    Abstract: PROBLEM TO BE SOLVED: To reduce energy consumption of an exhaust valve actuator for a large-size two-cycle diesel engine. SOLUTION: The actuator is movable between a close position and an open position, and is provided with a double-acting hydraulic piston having a hydraulic chamber for closing and a hydraulic chamber for opening. A double-acting spring member is connected to the double-acting hydraulic piston, and forms a spring mass system together with the mass of a spindle of the exhaust valve actuator and other members interlocking with it. The double-acting spring member stores energy while the exhaust valve actuator is parallelly moved between the close position and the open position in the longitudinal direction, and prepares for the next propulsion of the exhaust valve actuator to the opposite direction. An on/off type hydraulic valve alternately performs connection to a high pressure source of the hydraulic chamber for closing, connection to a tank of the hydraulic chamber for opening, and connection to the opposite direction. When the exhaust valve actuator is in the open position, and the hydraulic chamber for opening is connected to the high pressure hydraulic fluid source, closing force of the double-acting spring is balanced with opening force of the hydraulic chamber for opening.

    Abstract translation: 要解决的问题：为了降低大型二冲程柴油发动机的排气阀致动器的能量消耗。 解决方案：致动器在关闭位置和打开位置之间可移动，并且设置有具有用于关闭的液压室和用于打开的液压室的双作用液压活塞。 双作用弹簧构件连接到双作用液压活塞，并与排气阀致动器的主轴的质量和与其互锁的其它构件一起形成弹簧质量系统。 双作用弹簧构件在排气门致动器在关闭位置和纵向方向上的打开位置之间平行移动时存储能量，并且为排气阀致动器的下一个推进准备相反的方向。 开/关型液压阀交替地连接到液压室的高压源，用于关闭，连接到用于打开的液压室的罐，并且连接到相反的方向。 当排气阀致动器处于打开位置，并且用于打开的液压室连接到高压液压流体源时，双作用弹簧的闭合力与用于打开的液压室的打开力平衡。 版权所有（C）2009，JPO＆INPIT
