A low noise valve train for actuating poppet valves in an internal combustion engines includes a camshaft cam profile including a preopening bluff ramp to compress the valve train prior to opening each valve with its opening ramp and a post closing bluff ramp to quickly release compression of the valve train after closing of each valve with its closing ramp together with opening and closing ramps yielding low velocity opening and closing of the valves. The result is a combination of valve train pre and post compression to obtain low opening and closing velocities for the valves while avoiding extended operation with the valve train compressed by the action of the associated bluff ramps.
