Abstract: 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.

Abstract: An exhaust system including a selective catalytic reduction (SCR) component and an oxidation catalyst component. The exhaust system also includes an exhaust treatment fluid injection system for dispersing an exhaust treatment fluid into an exhaust stream at a location adjacent either the SCR component or the oxidation catalyst component, wherein the exhaust treatment fluid injection device includes a common rail that provides the exhaust treatment fluid under pressure to a plurality of injectors that dose the exhaust treatment fluid into the exhaust stream. The exhaust treatment fluid injection device also includes a return rail for returning unused exhaust treatment fluid to the fluid source. Each of the common rail and return rail can be configured to allow drainage of the exhaust treatment fluid as a freeze-protection feature.
