Automobile oxygen sensor is a key feedback sensor in the control system of electric injection engine. It is also a key part to control automobile exhaust emission, reduce automobile pollution to environment and improve the quality of automobile engine fuel combustion. The oxygen sensor is installed on the engine exhaust pipe.
Application: Cars

China's industrial robot market is mainly concentrated in aerospace, automotive, auto parts, motorcycles, electrical appliances, engineering machinery, petrochemical, electric power and other industries.
China's robot market is growing rapidly, and the International Robotics Federation predicts that by 2014 China will become the world's largest robot market. However, China's robot industry has just begun, and international giants occupy nearly 80% of the market share in the Chinese market. According to the statistics of the Higher Industrial Research Institute (GGII), there were 33,000 industrial robots in China in 2012, including 22,000 imported robots, accounting for 66.67%. Among them, ABB has the largest market share, followed by FANUC, Yaskawa and KUKA.
The robot industry chain is mainly divided into three parts: upstream is component production, downstream is robot assembly, and finally system integration application. In the business model, there are more than 1,000 system integrators in the domestic robot industry, which are outsourcing or OEM, providing turnkey projects for customers, but fewer companies involved in the development and production of key components. At present, there are only a few local leading enterprises such as Xinsong.
It is difficult to open the domestic robot market because the manufacturing cost is too high, and due to the lack of core technology of key components, the parts of domestic robots are basically dependent on imports, and the cost is high, so the cost performance is low, and customer acceptance is not high. The downstream market cannot open the scale. It is reported that in 2012, the annual output of domestic industrial robot enterprises was less than 500 units, and the sales of local brand robots was only 11,12 units, with a market share of only 4%. Most of the market was occupied by joint ventures and wholly-owned brands.
However, the capital market has been popular with robotic concept stocks. Due to the frequent spread of foreign technology and technology news, since June 25, 18 of the 19 robot concept stocks have outperformed the Shanghai Composite Index in the same period, of which 14 stocks have accumulated during the period. The increase is more than 10%, accounting for 73.68%.
A: The only way to know if the O2 sensor is functioning normally is to check its responsiveness to changes in the air/fuel mixture, by Voltage Measurement or Waveform Simulation.
Use a 10-megaohm digital voltmeter. Hook up the voltmeter's red probe to the sensor's signal wire and the black probe to engine ground. (Use back probe method, DO NOT pierce the wire.) For a good sensor, voltage should fluctuate constantly between 0.1 and 0.9 volts after starting the engine for 2 or 3 minutes.
The analysis believes that the robot industry will be an emerging large-scale high-tech industry emerging after automobiles and computers. The "Twelfth Five-Year Plan" is a key turning point in the development of China's industrial robot industry. The state's policy support for the robot industry is gradually increasing, and market demand will develop in a blowout manner. The demand for industrial robots will be 15% to 20% per year. increase.
