A configuration for a V type double overhead cam shaft engine comprising a crank shaft, a left cylinder bank with a left bank cylinder head, and a right cylinder bank with a right bank cylinder head, wherein: (a) a left bank intake cam shaft is fitted to said left bank cylinder head and a right bank intake cam shaft is fitted to said right bank cylinder head, said left bank intake cam shaft being substantially identically formed to said right bank intake cam shaft and being fitted in reversed alignment thereto; (b) a left bank exhaust cam shaft is fitted to said left bank cylinder head and a right bank exhaust cam shaft is fitted to said right bank cylinder head, said left bank exhaust cam shaft being substantially identically formed to said right bank exhaust cam shaft and being fitted in reversed alignment thereto; (c) a pair of the same type of said cam shafts are driven in a determinate phase relationship with said engine crank shaft; (d) a pair of left bank gears, with the same number of teeth, are provided one on said left bank intake cam shaft and one on said left bank exhaust cam shaft, and mesh together so as to rotationally couple together said left bank intake cam shaft and said left bank exhaust cam shaft in a determinate phase relationship; (e) a pair of right bank gears, with the same number of teeth, are provided one on said right bank intake cam shaft and one on said right bank exhaust cam shaft, and mesh together so as to rotationally couple together said right bank intake cam shaft and said right bank exhaust cam shaft in a determinate phase relationship; and (f) at said left cylinder bank and at said right cylinder bank, the number n of teeth of the phase difference of said pairs of gears is determined by the equation: n=(gamma/180°)N where gamma is the phase difference angle of the intake cam shaft and the exhaust cam shaft, and N is the number of teeth on the gears.

A configuration for a V type double overhead cam shaft engine comprising a crank shaft, a left cylinder bank with a left bank cylinder head, and a right cylinder bank with a right bank cylinder head, wherein: (a) a left bank intake cam shaft is fitted to said left bank cylinder head and a right bank intake cam shaft is fitted to said right bank cylinder head, said left bank intake cam shaft being substantially identically formed to said right bank intake cam shaft and being fitted in reversed alignment thereto; (b) a left bank exhaust cam shaft is fitted to said left bank cylinder head and a right bank exhaust cam shaft is fitted to said right bank cylinder head, said left bank exhaust cam shaft being substantially identically formed to said right bank exhaust cam shaft and being fitted in reversed alignment thereto; (c) a pair of the same type of said cam shafts are driven in a determinate phase relationship with said engine crank shaft; (d) a pair of left bank gears, with the same number of teeth, are provided one on said left bank intake cam shaft and one on said left bank exhaust cam shaft, and mesh together so as to rotationally couple together said left bank intake cam shaft and said left bank exhaust cam shaft in a determinate phase relationship; (e) a pair of right bank gears, with the same number of teeth, are provided one on said right bank intake cam shaft and one on said right bank exhaust cam shaft, and mesh together so as to rotationally couple together said right bank intake cam shaft and said right bank exhaust cam shaft in a determinate phase relationship; and (f) at said left cylinder bank and at said right cylinder bank, the number n of teeth of the phase difference of said pairs of gears is determined by the equation: n=(gamma/180°)N where gamma is the phase difference angle of the intake cam shaft and the exhaust cam shaft, and N is the number of teeth on the gears.
Claim 3
Dependent Claim
