A reduction method for a catalytic converter in an exhaust system of an internal combustion engine for reducing the oxygen content in the catalytic converter, in particular after an overrun fuel cutoff mode of the internal combustion engine, the method including first injection of fuel into a first…

The present invention is directed at the integration of a solid oxide fuel cell (SOFC) into the exhaust stream of an internal combustion engine aided by the upstream injection of a fuel, such as a hydrocarbon fuel. The internal combustion engine may be advantageously operated in a lean condition…

Provided is an exhaust-pipe injection system capable of accurately monitoring a lowered injection pressure generated in a fuel line due to exhaust pipe injection and appropriately perform feedback control for the exhaust injection amount. The exhaust-pipe injection system includes: an exhaust pipe…
