CV & HEV Detecting Sensor-Product-奕微科半導體

Premium quality, manufactured to a high-level standard

Our CV & HEV detecting sensors keep the exhaust and fuel systems under real-time watch. The NOx Sensor measures nitrogen oxides in the exhaust gas and the Common Rail Pressure Sensor measures fuel rail pressure in diesel engines, so the Engine Control Unit (ECU) can manage emissions, fuel efficiency and engine performance.

Key functions

01
Real-time measurement

Measures nitrogen oxide concentration in the exhaust gas, or fuel rail pressure in the common rail system, in real time.
02
ECU-controlled adjustment

Readings go to the Engine Control Unit (ECU), which adjusts the exhaust after-treatment system (such as SCR) or the fuel injection accordingly.
03
Efficiency and emissions

Optimized combustion helps improve fuel efficiency and engine performance while reducing emissions and environmental pollution.
04
Diagnostics

The vehicle's diagnostic system uses the sensor data to detect problems and generate diagnostic trouble codes (DTCs) for accurate problem identification.

Products

NOx Sensor

Measures the concentration of nitrogen oxides (NOx) in a vehicle's exhaust gas, with specifications that follow the Continental spec.
