  • Patent number: 10208651
    Abstract: In certain embodiments, a unique method and pre-combustion chamber (PCC) structure may ensure very efficient flame propagation of lean fuel-air mixture in natural gas engines by reducing the amount of fuel admitted to the PCC. A PCC may include an enclosed volume of 1-3% of the main combustion chamber volume, with a spark plug and a fuel passage located opposite one or more PCC discharge nozzles to create a relatively richer fuel-air mixture with relatively lower turbulence in the spark plug region and a relatively leaner fuel-air mixture with relatively high turbulence in the nozzle region, which can be reliably and efficiently ignited, resulting in a high velocity flame jet/torch emerging from the prechamber into the main chamber. The PCC may be threaded with a 22 mm×1.5 or ??-18 thread size, to allow the PCC to be screwed into a cylinder head in place of a spark plug.

  • Patent number: 8050848
    Abstract: A method and system for igniting a lean fuel mixture in a main chamber of an internal combustion engine by igniting a rich air-fuel mixture in a pre-combustion chamber which is fuelled using a controlled valve. For a stable and consistent ignition of the main chamber and simultaneous reduction of emission of the internal combustion engine, a closed loop control adjusts the fuel amount and the fuelling time for the pre-combustion chamber in order to achieve a light off in an optimal time window and by sufficient ignition energy.
