Abstract
Separation of carbon dioxide from the exhaust of an internal combustion engine, the production of hydrogen from water, and reformation of carbon dioxide and hydrogen into relatively high-octane fuel components.
Claims14
An internal combustion engine comprising:
- an engine control system in communication with said engine that detects and evaluates the presence of engine knock;
- a carbon dioxide separator to separate carbon dioxide from internal combustion engine exhaust;
- a condenser and electrolyzer to separate water from said engine exhaust and provide hydrogen;
- a reformer that converts said separated carbon dioxide and hydrogen into one or more high octane fuel components;
- wherein said engine control system is configured to introduce said one or more high octane fuel components into said engine upon determination that said engine requires said one or more components to mitigate and/or prevent engine knock.
2 more elements
A method of operating an internal combustion engine comprising:
- injecting fuel into a combustion chamber to form an air-fuel mixture and combusting said mixture and forming exhaust gas;
- providing a carbon dioxide separator and separating carbon dioxide from said exhaust gas;
- separating water from said exhaust gas and converting said water into a supply of hydrogen;
- combining said separated carbon dioxide and hydrogen and forming one or more high octane fuel components;
- providing an engine control system that detects and evaluates the presence of engine knock;
- mitigating or preventing engine knock by introducing said one or more high octane fuel components into said internal combustion engine.
