Carbon Dioxide Recirculation System

摘要

A system may include an engine, an exhaust passage, a carbon dioxide capture system, and a dosing valve. The engine includes a combustion chamber. The exhaust passage receives exhaust gas from the engine. The carbon dioxide capture system receives exhaust gas from the exhaust passage and may include a separation device, a pump and a first tank. The separation device removes carbon dioxide from the exhaust gas. The pump pumps the removed carbon dioxide to the first tank. A second tank may receive and store carbon dioxide from the first tank. The dosing valve may be in fluid communication with and disposed downstream of the second tank. The dosing valve may regulate a flow of carbon dioxide from the second tank to the engine.
