摘要：
A reciprocating internal combustion engine has a pilot mask situated about the intake valve seat and extending into the engine cylinder and a variable camshaft timing drive system which positions the camshaft such that the lift of the intake valve and the height of the pilot mask are approximately equal when the piston is moving at the point of its greatest velocity during the intake stroke.
