摘  要：
Based on the Bosch's LSU4.9 wide-band oxygen sensor, the PID algorithm is designed to control the operating temperature of the oxygen sensor to ensure normal operation of the oxygen sensor. The air-fuel ratio signal of the oxygen sensor is collected in real time and input into the air-fuel ratio control algorithm to complete the air-fuel ratio closed-loop control. Based on the CJ125 driver chip, the drive for oxygen sensor is completed by SPI communication. Based on the six-cylinder heavy-duty natural gas engine, calibration test of the control software of oxygen sensor is completed. The test proves that the software can control the oxygen sensor to accurately collect the signals, and the air-fuel ratio closed-loop control can effectively improve the fuel economy and power performance of the engine.
