Abstract
Embodiments disclosed herein relate to internal combustion engines, combustion systems that include such internal combustion engines, and controls for controlling operation of the combustion engine. The internal combustion engine may include one or more mechanisms for injecting fuel, air, fuel-air mixture, or combinations thereof directly into one or more cylinders, and controls may operate or direct operation of such mechanisms.
Claims22
1-27. (canceled)
A controller for operating an internal combustion engine that includes one or more combustion chambers and an output shaft rotatable in response to combustion of fuel in the combustion chambers, the controller comprising:
- a processor;
- and
- a memory coupled to the processor and containing computer-executable instructions that, when executed by the processor cause the controller to perform the acts of:
- receiving one or more operation inputs related to an operating parameter of the internal combustion engine;
- receiving one or more inputs from one or more sensors;
- determining an amount of air to inject into the one or more combustion chambers of the internal combustion engine;
- and
- operating at least one of one or more air injectors or one or more air valves to inject air into the one or more combustion chambers of the internal combustion engine in a manner that produces predetermined combustion volumes in corresponding ones of the one or more combustion chambers.
(canceled)
A computer controlled internal combustion engine system, comprising:
- an internal combustion engine including:
- an output shaft;
- one or more combustion chambers;
- an energy conversion mechanism configured to convert a pressure increase in the one or more combustion chambers into rotation of the output shaft;
- and
- one or more air injectors operably connected to corresponding ones of the one or more combustion chambers, mechanically decoupled from the output shaft, and configured to unobstructedly inject air into the one or more combustion chambers;
- a controller operably coupled to the one or more air injectors, the controller being configured to:
- receive one or more operation inputs related to an operating parameter of the internal combustion engine;
- receive one or more inputs from one or more sensors;
- determine the amount of air to inject into one or more combustion chambers of the internal combustion engine;
- and
- operate one or more air injectors to directly inject air into the one or more combustion chambers of the internal combustion engine in a manner that produces predetermined combustion volumes in corresponding ones of the one or more combustion chambers.
A method of operating an internal combustion engine, the method including:
- receiving one or more operation inputs related to an operating parameter of the internal combustion engine;
- receiving one or more inputs from one or more sensors;
- determining the amount of air to inject into one or more combustion chambers of the internal combustion engine;
- producing a predetermined combustion volume in corresponding ones of the one or more combustion chambers by injecting a predetermined amount of air into the one or more combustion chambers of the internal combustion engine by operating one or more air injectors operably connected to the one or more combustion chambers;
- injecting a predetermined amount of fuel into the one or more combustion chambers of the internal combustion engine;
- and
- combusting the fuel in the one or more combustion chambers, thereby rotating an output shaft of the internal combustion engine.
