초록 ▼

A system has an engine. The engine has a combustion chamber, a pre-combustion chamber apart from the combustion chamber, and an opening spanning between the combustion chamber and the pre-combustion chamber. The engine also has a first fuel supply system adapted to supply liquid fuel to the pre-combustion chamber and a second fuel supply system adapted to supply a second, different fuel to the combustion chamber. In certain instances, an oxygen supply system supplies oxygen into the prechamber.

대표청구항 ▼

1. A system, comprising: an engine comprising: a combustion chamber;a pre-combustion chamber apart from the combustion chamber;an opening spanning between the combustion chamber and the pre-combustion chamber;a first fuel supply system adapted to supply liquid fuel to the pre-combustion chamber; anda second fuel supply system adapted to supply a second, different fuel to the combustion chamber, the second fuel supply system comprising a fuel gas fuel injector with an outlet to the pre-combustion chamber. 2. The system of claim 1, where the liquid fuel is diesel fuel. 3. The system of claim 1, where fuel gas comprises natural gas, biogas, landfill gas, or methane. 4. The system of claim 1, comprising a glow plug in the pre-combustion chamber. 5. The system of claim 1, where the first fuel supply system comprises a liquid fuel injector with an outlet to the pre-combustion chamber. 6. The system of claim 1, where the first fuel supply system is adapted to supply the liquid fuel as a pilot fuel to ignite the fuel gas; and where the second fuel supply system is adapted to supply the fuel gas to the combustion chamber as a primary fuel. 7. The system of claim 6, where the second fuel supply system is adapted to supply the fuel gas to the combustion chamber at a lambda of 1.5 or greater. 8. The system of claim 6, where the first fuel supply system is adapted to supply the liquid fuel as a primary fuel. 9. The system of claim 1, comprising an oxygen supply adapted to supply an oxygen flow to the pre-combustion chamber. 10. The system of claim 1, where the opening spanning between the combustion chamber and the pre-combustion chamber comprises a jet aperture. 11. A method, comprising: operating an engine on liquid fuel supplied directly into a pre-combustion chamber of the engine, the pre-combustion chamber residing apart from a combustion chamber of the engine; andoperating the engine on the liquid fuel supplied directly into the pre-combustion chamber of the engine and a second, different fuel supplied into the combustion chamber, the second fuel supplied into the combustion chamber through the pre-combustion chamber. 12. The method of claim 11, where the liquid fuel is diesel fuel. 13. The method of claim 11, where operating the engine on liquid fuel supplied directly into the pre-combustion chamber and the second fuel supplied into the combustion chamber comprises igniting the second fuel with the liquid fuel. 14. The method of claim 13, where the second fuel comprises fuel gas. 15. The method of claim 13, comprising supplying an oxygen flow directly to the pre-combustion chamber.
