The advantages

Technical Advantages compared with conventional four cycle engines

  • No valves, no valve train, no camshaft

  • Substancial reduction of mechanical noises

  • No limits of engine revolutions caused by valve operation

  • Reduction in engine height and engine compartment dimensions

  • The cylinder block and cylinder head can be manufactured in a single place

  • Reduction of the number of parts required for the creation of the fuel-/air mixture and for the ignition in Otto engines

  • Half the number of injection nozzles and pump parts in Diesel engines

  • Reduction in friction due to elimination of the valve system

  • Reduction in vacuum performance at lower rpm

  • Improved creation of fuel-/air mixture at lower rpm caused by higher flush pressure and higher optimised velocity of introduction of the mixture into the combustion chamber

  • Greater thermal efficiency by half the number of combustion cylinders for a given kilowatt output

  • Higher thermal efficiency caused by higher compression

  • Optimal design of the combustion chambers due to:

    The relation of surface area to volume

    Squeeze flowing in the TDC of the chamber caused
    by an uninterrupted circular form of the squeeze area

    Shorter flame path

  • Constant temperatures in the combustion chambers due to the abscence of very hot exhaust valves

  • Higher heat density in the exhaust channel due to the greater ignition frequency. For high performance engines, if a catalytic converter is required, its operation occurs earlier
