PROBLEM TO BE SOLVED: To provide a V shape reciprocating internal combustion engine capable of reducing noise and vibration generated due to action difference of pistons in each bank. SOLUTION: In the V shape reciprocating internal combustion engine, piston pin offset is established for each bank to keep direction and magnitude of moment around a piston pin generated to the piston of each bank roughly equal. Consequently, piston slap can be prevented, action difference of pistons of each bank can be reduced and noise and vibration performance can be improved. COPYRIGHT: (C)2006,JPO&NCIPI
