Abstract

The invention belongs to the field of automobile engines, in particular to an automobile engine oxygen sensor voltage collection system. Aiming at the existing problems that the voltage of the oxygen sensor cannot be collected and the replacement of the oxygen sensor is inconvenient, the following scheme is proposed, which includes the engine, oxygen Sensor, voltmeter, can line and on-board computer. The oxygen sensor is connected to the engine, the voltmeter is connected to the oxygen sensor, and the voltmeter is connected to the on-board computer through the can line. There are two wires welded on the oxygen sensor, two wires One side of the oxygen sensor is socketed with the same plug-in, and the plug-in is plugged into the voltmeter, a clamping plate is fixedly socketed on the oxygen sensor, and a clamping block is fixedly installed on the engine. The present invention can collect the voltage of the oxygen sensor through the setting of the voltage changer, and then can know the state of the oxygen sensor, and can know it in time when it is damaged. At the same time, the oxygen sensor is easy to disassemble and assemble, so that the oxygen sensor can be easily replaced when it is damaged. .

Description

technical field [0001] The invention relates to the technical field of automobile engines, in particular to an automobile engine oxygen sensor voltage acquisition system.
