Embodiment Construction

[0033] Embodiments described herein relate to controlling a compression ignition engine and aftertreatment of exhaust gases produced by the engine. Specifically, some embodiments relate to controlling compression-ignition engines such that when the engine is running producing power at or near its capacity, NO x emissions. Additionally, some embodiments relate to improving the transient response required for compression ignition engines with exhaust gas recirculation when increasing power and limiting the emissions of nitrogen and oxygen compounds.

[0034] Some embodiments will be described more fully hereinafter with reference to the accompanying drawings in which embodiments are shown. Like reference numerals refer to like parts throughout the drawings. Other embodiments may, however, take many different forms and are not limited to the embodiments described herein. These embodiments are just examples. Rights based herein include the full scope indicated by the claims. ...

Abstract

A method for controlling an internal combustion engine is used for limiting the emission of unfavorable NOX, and the instantaneous power is increased.

Description

[0001] related application [0002] This application claims priority to U.S. Application Serial No. 61 / 540073, filed September 28, 2011, and U.S. Application Serial No. 61 / 557077, filed November 8, 2011, the contents of which are incorporated by reference in their entirety here. [0003] field of invention [0004] The invention relates to the operation of compression ignition internal combustion engines and exhaust gas aftertreatment to limit nitrogen oxide emissions. Embodiments relate to operation in which the power of the engine is increased momentarily. [0005] technical background [0006] Internal combustion engines are widely used to drive electric generators, motor vehicle engines, and the like. Exhaust emissions from internal combustion engines and their impact on the environment are a growing concern. Because of these concerns, several regulations have been adopted to limit the amount of various exhaust gases that may be emitted into the environment from these e...
