An engine comprising a camshaft, the engine coupleable to an auxiliary device driven from the camshaft, the camshaft comprising: a plurality of valve cams each configured to actuate a respective intake valve or exhaust valve of the engine, an angular orientation of the valve cams about the rotational axis of the camshaft defined by the operational requirements of the valves; and an auxiliary device cam configured to actuate a drive element of the auxiliary device via one or more cam lobes, the auxiliary device cam having an angular orientation about the rotational axis of the camshaft, and the drive element having an angular orientation about the rotational axis of the camshaft, wherein the angular orientation of the drive element of the auxiliary device is selected respective to the angular orientation of the valve cams such that each actuation event of the auxiliary device occurs between two successive valve actuation events.

Arrangement for reducing torsional loading of a camshaft

A system and method comprising four valves per cylinder of a multi-cylinder engine is provided to control cylinder intake and exhaust valves independently from other cylinders in response to engine operating conditions. The engine valve deactivation system for the engine may comprise two or more cylinders wherein each cylinder has two exhaust valves and two inlet valves. The system and method may allow for cylinder deactivation and/or high swirl to both be delivered.
