Abstract (en)
[origin: GB2415745A] An engine has a crankshaft, and a camshaft formed of two concentric rotary members 50, 52 at least one of which carries a group of cams 54. A transmission train drives one of the rotary members 52 in fixed phase relationship with the crankshaft and a phaser 12 serves to enable the phase of the other rotary member 50 to be varied dynamically relative to the phase of the crankshaft and the first rotary member 52. The invention uses the unphased rotary member 52 to drive an auxiliary device 16, such as a diesel pump, so that the reaction torque of the auxiliary device 16 does not affect the operation of the phaser 12.
