Abstract
There are provided systems and methods for the use of rich limit extenders, and in particular pre-chamber assemblies, for increasing the ability of a spark-ignition engine to operate under fuel-rich conditions. In embodiments the pre-chamber assemblies are combined with spark-ignition engines as a reformer in a gas-to-liquid system for converting a combustible fuel source into synthesis gas. Embodiments of the reformers having pre-chambers provide a synthesis gas product having a H2/CO ratio, with increased H2 concentrations.
Claims7
A device for extending the rich operating fuel limit of an engine, the device comprising:
- a. a body defining a pre-chamber cavity;
- b. an ignition source in communication with the pre-chamber cavity;
- c. an inlet conduit, wherein the inlet conduit has a first end configured for receiving an oxidation source gas and a second end configured to provide the oxidation source gas to the pre-chamber cavity, and wherein the inlet conduit has a check valve located between the first end and the second end;
- d. the pre-chamber cavity having a first end and a second end, wherein the second end has a nozzle having a plurality of holes;
- and,
- e. the body configured for attachment to an engine.
