Abstract
A reciprocating internal combustion engine has at least one camshaft for actuating intake and exhaust valves and a camshaft drive for rotating the camshaft and for adjusting the rotational timing of the camshaft with respect to the crankshaft. A charge motion control valve and the variable camshaft timing mechanism are both used to selectively impart angular momentum to charge entering the engine's cylinder(s).
