System for reducing engine emissions and backpressure using parallel emission reduction equipment

摘要

An exhaust emission reduction system for a fuel injected engine system has a plurality of emission reduction components configured to process the exhaust gas. The emissions reduction components include of one or more NO_X reduction components and one or more filtration components configured to reduce particulate matter, hydrocarbons and/or carbon monoxide emissions. Each engine cylinder is associated with a respective one of the emission reduction components, such that exhaust gas from each engine cylinder flows through the respective one emission reduction component in parallel with the exhaust gas flows from the other cylinders through their respective emission reduction components.
