Description

Signal transmission line configuration structure of oxygen sensor

This creation is about a signal transmission line configuration structure of an oxygen sensor, especially a signal transmission line configuration structure of an oxygen sensor with a pipeline fixed structure formed on the footrest.

Today’s commonly used personal transportation vehicles generally include automobiles and locomotives. The locomotive type of transportation is a two-wheeled, three-wheeled or four-wheeled vehicle that generates power from an engine and mainly uses the handle to control the direction. It is simple to operate, convenient to move, and cost-effective. The feature of low cost has become the most commonly used means of transportation.

The main purpose of the oxygen sensor (Oxygen Sensor or O2 Sensor) installed in the exhaust system of locomotive engines is to monitor the "air-fuel ratio" of gasoline and oxygen in the engine. The information of the oxygen content in the exhaust gas detected in the tube is sent back to the engine control unit (ECU: Engine Control Unit) of the locomotive. Too much oxygen means that the air-fuel ratio is too lean, and too little oxygen means that the air-fuel ratio is too rich. If it is too lean, the engine control unit will drive the injector to inject more fuel to enrich the gas. If the air-fuel ratio is too rich, the engine control unit will control the injector and make it inject less fuel, so that the engine control unit will quickly Under the control of the operation, the most appropriate air-fuel ratio can be adjusted quickly, so that every drop of oil can play the best efficiency and achieve fuel-saving effect. Therefore, the oxygen sensor can be used to determine whether the exhaust gas in the exhaust pipe is too rich or too lean.

Locomotive engines are the main source of locomotive power. Good engine design is particularly important. Among them, the configuration of pipelines is one of the key points of the design. The pipelines include wires, signal transmission lines, gas pipes, oil pipes, water pipes, etc., and most of the pipeline connections are Connectors or sensors use various pipelines as a communication bridge to maintain the functioning of the entire vehicle.

In addition, when a locomotive is running, the engine and the frame will move relative to each other, along with pulling the pipelines connected between the frame and the engine. Therefore, it is necessary to fix the pipelines in the design to prevent the pipelines from rubbing against each other and cause damage, while being tidy. The pipeline configuration can facilitate the installation and maintainability of subsequent projects, which are factors that need to be considered in the design.

For locomotives currently on the market, the fuel injection engine must have an upstream oxygen sensor inside to detect the exhaust pollution value. It is usually installed upstream of the catalytic converter in the exhaust channel to detect the exhaust pollution value. Feed back to the Electronic Control Center (ECU), which controls the air-fuel ratio of the engine by controlling the amount of fuel injected by the injectors to maintain the most suitable mixing ratio in each operating state. As pollution regulations become more and more stringent, the traditional upstream oxygen sensor cannot monitor the degradation of the catalytic converter. Therefore, a downstream oxygen sensor must be installed downstream of the catalytic converter to detect the degradation of the catalytic converter. degree.

The signal transmission line of the oxygen sensor is the key to transmitting the exhaust pollution value. Its trend and fixed storage are relatively important. In addition, if the signal transmission line is configured with an excessively long suspended section, it is easy to be used in an environment where the vehicle is highly vibrated. , Causing fatigue and fracture inside the signal transmission line, making maintenance difficult, and misjudgment of exhaust pollution value detection; and because there are two oxygen sensors on the exhaust channel at the same time, the signal transmission line is likely to cause misinstallation and signal during maintenance.
