I'm with MAN Diesel & Turbo and here is a cross section view of our ultra long stroke G95ME two cycle marine propulsion diesel engine which have no camshafts. The exhaust valves and fuel injection are hydraulicly actuated by a computer controlled servo system. The largest examples have a bore of 95 cm (37.5 inch) and stroke of 346 cm (11.35 feet). The 12 cylinder version of this engine produces 112,000 hp @ 85 rpm.
