Energy Conservation and Emission Reduction in Automobiles Rely on This New Type of Gas Sensor
Building an ecological civilization has long been a key priority for people’s well-being and an integral part of realizing the Chinese Dream of national rejuvenation. Energy conservation and emission reduction stand as an eternal theme for the development of the automotive industry. Stepping up efforts in this field has become an urgent necessity for the sound and rapid growth of China’s economy. Meanwhile, amid global industrialization, the massive consumption of fossil fuels has exerted severe impacts on the environment.
In the
12th Five-Year Plan for Energy Conservation and Emission Reduction issued by the State Council, the state has refined and quantified relevant measures and targets for key regions and industries. Against this backdrop, the market for emission monitoring instruments including
oxygen sensors, which are used to monitor smoke emissions and combustion efficiency, will see explosive growth.
Generally speaking, automobiles and factories are the major sources of gas emissions. With the growing popularity and rising number of vehicles, environmental and energy issues have become increasingly prominent. For this reason, a growing number of scientists and technicians are applying energy-saving and emission-reduction technologies to new-generation automobiles and developing eco-friendly new power sources. Among these technologies, oxygen sensors help cut energy consumption and exhaust emissions by detecting and analyzing the composition of vehicle exhaust.
Most automobiles today still adopt internal combustion engine powertrains. The complete combustion of fuel directly affects power output and exhaust composition. Insufficient air intake leads to incomplete combustion, resulting in fuel waste and excessive pollutant emissions. Excess air intake, on the other hand, undermines vehicle power.
Oxygen sensors detect oxygen content in exhaust gas and adjust air intake accordingly, which improves combustion efficiency and energy conversion rate, and curbs harmful exhaust emissions.
Vehicle exhaust contains various gases such as oxygen (O₂), carbon monoxide (CO), carbon dioxide (CO₂), lead compounds and sulfur oxides. Specialized sensors are required to detect and regulate these different gases, so as to boost fuel combustion efficiency, raise energy conversion rates and reduce toxic exhaust. Currently, the main gas sensors applied in automobiles are oxygen sensors and carbon dioxide concentration sensors.
The S+AOX developed by
Shenzhen Wuliang Sensor Technology Co., Ltd. is a long-service-life lead-free oxygen sensor specially designed for flue gas analysis. Classified by measuring range and service life, it is primarily used to detect ambient oxygen concentration. It is a widely applied sensor for automotive energy conservation and emission reduction, and also one of the best-selling gas sensors of Shenzhen Sandt.
While the automotive industry opens up a vast market for gas sensors, it also sets strict requirements on technical specifications and cost. Sensitivity, response speed and repeatability are the basic criteria for such sensors.
High measurement accuracy, reliability and low cost are essential for automotive gas sensors: precise measurement enables more accurate operational control; automotive-grade reliability ensures stable performance under extreme conditions including extreme temperatures, humidity, vibration and electrical load. In addition, low cost is a mandatory requirement, as domestic automakers maintain stringent cost standards. These are the core goals that domestic sensor enterprises strive to achieve.
We will continue to provide products that meet stringent quality standards, as well as accurate and reliable gas detection solutions, to fully satisfy diverse client demands in pursuit of the overarching goal of energy conservation and emission reduction.
