Piston engine with a three valve cylinder head

摘要

The engine has a first inlet valve (2) and an exhaust valve (3) in a first half of the combustion chamber and a second inlet valve (2') in the second half with an operating device (7), e.g. an injection nozzle or ignition plug, mounted in the cylinder head between the spin-generating inlet channels (4') and the exhaust channel (5). The operating device is essentially central in the combustion chamber and parallel to the cylinder axis. The three valves are controlled by a camshaft via transfer elements. The first inlet valve and the outlet valve are controlled via rocker levers (10,10'). The second inlet valve is controlled via a push rod (11) or drag lever.
