基于缸内内容确定发动机排出NO<base:Sub>X</base:Sub>的系统和方法
摘要：
一种装置包括发动机模块、缸内内容模块和发动机排出NOx模块。发动机模块配置成解释关于发动机的气缸内的操作状态的发动机缸内数据，其中发动机缸内数据包括发动机转矩、发动机转速、轨道压力和喷射开始。缸内内容模块配置成解释关于发动机气缸内的操作状态的至少一个附加缸内数据点。发动机排出NOx模块配置成响应于发动机缸内数据和至少一个附加缸内数据点来确定发动机排出NOx量。
摘要（英）：

An apparatus includes an engine module, an in-cylinder content module, and an engine out NOx module. The engine module is structured to interpret engine in-cylinder data regarding an operating condition within a cylinder of an engine, wherein the engine in-cylinder data includes an engine torque, an engine speed, a rail pressure, and a start-of-injection. The in-cylinder content module is structured to interpret at least one additional in-cylinder data point regarding the operating condition within the cylinder of the engine. The engine out NOx module is structured to determine an engine out NOx amount responsive to the engine in-cylinder data and the at least one additional in-cylinder data point.
