Abstract: A partially deactivatable internal combustion engine has two cylinder banks 2R and 2L having cylinders. Some of the cylinders are deactivatable cylinders capable of deactivated by keeping engine valves for them closed and the rest are continuously working cylinders. A camshaft for a cylinder bank having the deactivatable cylinders drives an engine accessory, i.e. a fuel injection pump, whereby variation of camshaft driving torque can be suppressed.
