摘要： A system for interfacing with the ECU of an automotive vehicle for optimizing engine control to meet emission requirements or engineering targets for catalytic converter systems includes a secondary controller and an emission analyzer. The secondary controller monitors sensor input to the ECU and actuator output from the ECU so as to mimic an ECU actuator control function by generation of an operating parameter control map(s) functionally identical to that used by the ECU. The emission analyzer receives vehicle sensor input and additional emission data from a bench gas analyzer to similarly produce not only the parameter control map but also emission maps correlated to the operating parameter control map which are systemically changed to optimize emission conversion by the vehicle's catalytic converter system and modify the operating parameter control map. The modified control map is inputted to the secondary controller which bypasses the ECU to control the actuator function in accordance with the modified control map. Emission maps are subsequently generated and the modified control map further modified until conversion of emissions by the vehicle's catalytic converter system is optimized. The system permits engine control to assure emission regulation compliance without knowledge of the ECU's code while also providing design optimization of the catalytic converter.
摘要翻译：用于与机动车辆的ECU接口以便优化发动机控制以满足排放要求或催化转换器系统的工程目标的系统包括二级控制器和排放分析器。次级控制器监视ECU的传感器输入和ECU的执行器输出，以通过生成与ECU使用的功能相同的操作参数控制图来模拟ECU执行器控制功能。发射分析仪从台式气体分析仪接收车辆传感器输入和附加发射数据，以类似地产生参数控制图，而且还产生与操作参数控制图相关的发射图，其被系统地改变以优化车辆催化转化器系统的排放转换并修改操作参数控制图。改变的控制图被输入到旁路ECU的二次控制器，以根据修改的控制图来控制致动器功能。随后产生排放图，并且改进的控制图进一步修改，直到车辆催化转化器系统的排放转化得到优化。该系统允许发动机控制，以确保排放调节的合规性，而不需要了解ECU的代码，同时也提供催化转化器的设计优化。

In some embodiments, the multi-zoned catalysts contain both radial and axial zones. The zones can be formed by deposition of segregated coating compositions (or washcoats) containing platinum group metals and pollutant adsorbent materials to form layers along the length and radius of the honeycomb substrate. The invention also relates to exhaust gas treating systems that incorporate the multi-zoned catalysts.
