Abstract
A method for operating an oxycombustion engine system includes passing a nitrogen-depleted gas, a fuel, and a recycled exhaust gas into a combustion chamber, combusting a mixture of the nitrogen-depleted gas, the fuel, and the recycled exhaust gas, thereby producing an exhaust gas including carbon dioxide, detecting a pressure of the recycled exhaust gas passed to the combustion chamber, determining whether the detected pressure of the recycled exhaust gas is less than a configurable pressure threshold, and in response to determining that the detected pressure of the recycled exhaust gas is less than the configurable pressure threshold, increasing the pressure of the recycled exhaust gas passed to the combustion chamber.

1-27. (canceled)
An oxycombustion engine system comprising:
- a combustion chamber;
- a mixing chamber in selective communication with the combustion chamber;
- a filtration chamber in communication with the mixing chamber, the filtration chamber comprising a filtration medium structurally configured to separate nitrogen from air;
- a recycled exhaust pressure sensor, wherein the recycled exhaust pressure sensor is structurally configured to detect a pressure of a recycled exhaust gas passed to the mixing chamber;
- at least one of a valve and a blower;
- and
- a controller communicatively coupled to the recycled exhaust pressure sensor and the at least one of the valve and the blower, the controller comprising a processor and a computer readable and executable instruction set, which when executed, causes the processor to:
- receive a signal from the recycled exhaust pressure sensor indicative of a pressure of the recycled exhaust gas passed to the combustion chamber;
- determine whether the detected pressure of the recycled exhaust gas is less than a configurable pressure threshold;
- and
- in response to determining that the detected pressure of the recycled exhaust gas is less than the configurable pressure threshold, direct the at least one of the valve and the blower to increase a pressure of the recycled exhaust gas passed to the combustion chamber.
An oxycombustion engine system comprising:
- a combustion chamber;
- a mixing chamber in selective communication with the combustion chamber;
- a filtration chamber in communication with the mixing chamber, the filtration chamber comprising a filtration medium structurally configured to separate nitrogen from air;
- a temperature sensor structurally configured to detect a temperature associated with the combustion chamber;
- at least one of a valve and a blower;
- and
- a controller communicatively coupled to the temperature sensor and the at least one of the valve and the blower, the controller comprising a processor and a computer readable and executable instruction set, which when executed, causes the processor to:
- receive a signal from the temperature sensor indicative of a temperature associated with the combustion chamber;
- determine whether the detected temperature is greater than a configurable temperature threshold;
- and
- in response to determining that the detected temperature is greater than the configurable temperature threshold, direct the at least one of the valve and the blower to increase a pressure of recycled exhaust gas passed to the combustion chamber.
