Two-stage precombustion chamber for large bore gas engines

In certain embodiments, a two-stage precombustion chamber may be used to reduce engine nox levels, with fueled precombustion chambers, while maintaining comparable engine power output and thermal efficiency. One or more fuel admission points may be located in either the first prechamber stage or the second prechamber stage. ... Prometheus Applied Technologies Llc

Lean-burn pre-combustion chamber

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. ...
