A ‌PM sensor‌ (Particulate Matter sensor) is a device that detects and measures the concentration of microscopic solid or liquid particles suspended in the air. Here's a breakdown of its key aspects: Function & Purpose‌ It specifically targets particulate pollutants like ‌PM2.5‌ (particles ≤ 2.5 ... Read More

Symptoms of a faulty exhaust gas temperature sensor may include the following issues: ‌Engine starting difficulties‌, especially when cold, due to improper signal transmission to the engine control unit ‌Unstable or rough idling‌, such as fluctuating RPMs or vibrations, caused by incorrect air-fuel ... Read More

The ‌exhaust temperature sensor‌ is a critical component in modern engine management systems with the following functions: Temperature Monitoring‌ Continuously measures exhaust gas temperatures in the exhaust system (e.g., near the turbocharger outlet or catalytic converter) and transmits real-time ...

In the case of a NOx sensor failure, the vehicle can usually still travel short distances, but it needs to be repaired as soon as possible to avoid potential risks. The following is a specific analysis and suggestions: Feasibility and precautions Feasibility of short-term driving NOx sensors are ... Read More

The AdBlue pump is an important part of the diesel vehicle exhaust aftertreatment system, and mainly undertakes the following core functions: Accurate metering and delivery of urea solution‌ The AdBlue pump accurately calculates and delivers the required amount of urea solution to the exhaust system ... Read More

The high price of AdBlue (diesel exhaust fluid) pumps is mainly caused by the following factors: 1. Technical complexity and production standards Precision manufacturing requirements AdBlue pumps need to work with the SCR (selective catalytic reduction) system, and the injection accuracy directly ...
