Abstract: A piston and an engine are provided that includes various precise configuration parameters, including dimensions, shape and/or relative positioning of combustion chamber features. More particularly, configuration parameters for a piston crown and a piston bowl located within the piston crown are provided. The piston bowl configuration results in a combustion process that yields decreased heat transfer to a cylinder head of the internal combustion engine as well as reduced NOx emissions.

Abstract: A diesel fuel composition is disclosed, as well as a method for reducing NOx and smoke emissions from a diesel engine at minimum fuel consumption which comprises adding to the diesel engine at least one diesel fuel or blending component for a diesel fuel which has a combination of a low T50 in the range of from 190°C to 28O°C, a high cetane number in the range of from 31 to 60, and optionally a high distillation curve slope in the range of from 58°C to 140°C, which combination is effective to afford a combination of the lowest NOx and smoke emissions at the lowest fuel consumption at independent engine control values for the diesel engine that are optimum to afford production of a combination of the lowest NOx and smoke emissions at the lowest fuel consumption, whereby the NOx and smoke emissions from the diesel engine are reduced by at least 10% and 15%, respectively.

Abstract: A system includes an engine, an exhaust conduit for the engine, a first SCR catalyst fluidly coupled to the exhaust conduit, and a second SCR catalyst fluidly coupled to the exhaust conduit at a position downstream of the first SCR catalyst. The system further includes an ammonia sensor positioned between the first and second SCR catalysts. A reductant doser is positioned upstream of the first SCR catalyst. The system includes a controller that determines an amount of NH 3 present from the NH 3 sensor, and computes an actuator response function from at least one operating condition of the first SCR catalyst. The actuator response function includes a reductant injector response as a function of the amount of NH 3 , and the actuator response function includes a response discontinuity. The controller further determines a reductant injection amount from the amount of NH 3 and the actuator response function, and provides a reductant injector command.
