Filed: 2001-11-26
Abstract: <P>PROBLEM TO BE SOLVED: To solve such problems that, though output improvement in a conventional internal combustion engine needs to burn a fuel in an amount as large as possible and also to enhance its combustion efficiency, since the locations of intake and exhaust valves and passages are fixed despite the limited timing of suction and discharge, the place capable of using in a necessary timing is limited and thus, the intake/exhaust efficiencies are poor, and further that, since the layout of wall face of the engine is limited for enhancing the above efficiencies, it is difficult to create the configuration for the above purpose, that is, configuration of a combustion chamber, that for air stream guiding or the like.  <P>SOLUTION: A common valve which is a common inlet or outlet usable for suction, exhaust or other equipment is used in replacement of the valves for a conventional intake/exhaust device installed on the wall face of the internal combustion engine, and the valves and passages branched to suction, exhaust or the like are installed at the outside (in view of a combustion chamber) of the common valve which does not contact the wall face.  <P>COPYRIGHT: (C)2003,JPO
