摘要： 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. A more efficient overall combustion characterized by low levels of NOx formation may be achieved by a two-stage precombustion chamber system while generating very high energy flame jets emerging from the second prechamber stage into the main combustion chamber. A first prechamber stage may be substantially smaller than a second prechamber stage. The volumes and aspect ratios of the two prechamber stages, along with the location of the electrodes within the first stage prechamber, the holes patterns, angles and the separate fueling, may be selected to create a distribution of fuel concentration that is substantially higher in the first stage prechamber compared to the second prechamber stage.

摘要： The invention relates to a device for a prechamber unit (10) of a gas engine, comprising a prechamber unit (10) in the form of an elongated body (12) arranged to be placed in an upper part of the engine's cylinder, and where the elongated body (12) comprises a prechamber gas valve (20) and an ignition means (22) arranged side by side, and one or more channels (24) for supply of fuel gas via the prechamber gas valve (20) to a prechamber (26) in a lower part of the elongated body (12). Said prechamber (26) comprises further in the axial direction, an elongated cavity (28) with nozzles (30) placed at the end for supply of ignited fuel gas to the engine's cylinder with the help of the ignition means (22). The elongated cavity (28) in the prechamber (26) is divided into several connected, and in cross-section, graduated or tapered cavities (28a, 28b, 28c), where an uppermost cavity (28a) is widest in the cross-sectional direction and a bottom cavity (28c) is narrowest in the cross-sectional direction.

摘要： An Elevated Expansion-Ratio Internal Combustion Engine has a substantially standard repeating four-stroke sequence for each cylinder, and the Engine includes for each cylinder: an intake valve, a combustion-gas exhaust valve, and a vapor return valve. A return manifold for vapor connects from the return valves of respective ones of the cylinders back into a passage ahead of a beginning portion of an intake manifold. Substantially during a predetermined part of each compression stroke in the sequence of strokes, the return valve opens after a closing of the intake valve, and thereafter closes at a time within the compression stroke corresponding to a predetermined position of the piston in the cylinder.
