Title: Internal combustion engine
Inventor: MORI YUKIO
IPC: F02D41/02
Filed: 2004-06-04
Abstract: <P>PROBLEM TO BE SOLVED: To prevent excessive noise from occurring in self-igniting operation.  <P>SOLUTION: This internal combustion engine is formed to be operated in such a state that a so-called "an offset amount ofs" which is a distance between a reference line CL passing a connection point A between a piston 32 and a connecting rod 33 and parallel with the axis of a cylinder 31 and the rotating center P of a crankshaft 35 is equal to a first offset amount ofs1. Since the rotating angle θ1 of the crankshaft equivalent to a period during which the piston 32 moves from a top dead center to a bottom dead center coming next to the top dead center is smaller than 180°, the volume of a combustion chamber 36 is suddenly increased when combustion gas expands in that period. As a result, since a cylinder pressure increase rate is not excessively increased, excessive burning noise does not occur.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
