摘要： An aged exhaust gas oxygen sensor (EGO) simulator is inserted between an exhaust gas oxygen sensor and an electronic control module for testing the response of fuel control and emission systems to various amounts of exhaust gas oxygen sensor aging/degrading. The sensor signal is input to a summing amplifier where a delay signal is added. Positive and negative summing amplifier outputs go through vernier and decade controls, which add delay, and then to a variable gain inverter. The difference signal is integrated and output to the summing amplifier as the delay signal and output to a ground offset control for shifting the waveform up and down before going out to the control module. The vernier and decade controls add delays to mimic an aged/degraded exhaust gas oxygen sensor.
摘要翻译：在废气氧传感器和电子控制模块之间插入老化的废气氧传感器（EGO）模拟器，用于测试燃料控制和排放系统对不同量的废气氧传感器老化/退化的响应。传感器信号被输入到加法延迟信号的加法放大器。正和负相加放大器输出通过游标和十进制控制，这增加了延迟，然后到可变增益逆变器。差分信号被积分并作为延迟信号输出到求和放大器，并输出到接地偏移控制器，用于在输出到控制模块之前上下移位波形。游标和十年控制增加了模拟老化/降解废气氧传感器的延迟。

摘要： Controlling ignition current in the ignition control system of an internal combustion engine includes determining the amount of time it takes current in the ignition coil to reach a desired or limit value and adjusting the time of starting ignition coil charging before spark firing to be substantially equal to the amount of time it takes ignition coil charging current to reach the desired or limit current value.
