OK ED. Time for machinist 101. a 4 stroke cycle GE or EMD prime mover has 4 valves in the cyl. head, 2 intake & 2 exhaust. In a 2 stroke cycle ( EMD 567,645,710 )there are 4 valves also but they're all exhaust valves. at the bottom of the piston stroke there is a ring of holes that open into an airbox that is supplied by the roots blowers or the turbo. then the cylinder fires every time the piston comes up. don't get snake bit, no reed valves. this ain't no chainsaw PS, EMD 2 strokes turn 905 RPM and EMD & GE 4 strokes 1050 RPM [:p]
