非道路国四柴油机控制系统开发与试验
Development and Testing of Control System for Non road National IV Diesel Engine
基于高性能的32位单片机SPC57平台，开发出基于一种改进的氮氧化物(NOx)排放预测算法的非道路国四柴油机控制系统软件。此算法作为 NOx排放预测模型建立的基础，通过自适应改变步长以应对不同空速下，考虑对流项、外加源项以及耗散项对广义连续方程的影响，在MCU的时间片内，实现对整个SCR后处理催化器的计算预测。主控策略设计引入了国际通用的V模式开发方式，基于TargetLink代码生成工具开发完成。基于编译平台完成系统软件的集成工作。整个软件控制…查看全部>>
Based on the high-performance 32-bit microcontroller SPC57 platform, an improved nitrogen oxide (NOx) emission prediction algorithm has been developed for the control system software of non road national four diesel engines.This algorithm serves as the basis for establishing a NOx emission prediction model, adaptively changing the step size to cope with different airspeed conditions, considering the effects of convection, external source, and dissipation ter…查看全部>>
