Sensors

BorgWarner is a leading supplier of automotive grade sensor technologies for gasoline and diesel engines, which play a key role in increasing fuel efficiency, and performance while reducing emissions. 

Our portfolio provides manufacturers with Exhaust sensor technology.

Exhaust Sensors

EGTS Sensor

Temperature sensors

Overview

The Exhaust gas temperature sensor (EGTS) measures the temperature of the exhaust gas, helping to protect critical components from overheating, as well as enhancing the DPF regeneration process.

Our sensors feature a robust design, extremely fast activation times and a broad temperature range, for a long-lasting, high performing part.

Features / Benefits

  • Accurate temperature detection – ranging from -40°C to +900°C
  • Fast response time - <11 milliseconds to jump 300°C
  • Robust, closed tip design highly resistant to heat, vibration and contamination
  • Platinum thin film RTD offers greater protection, response times and accuracy

Ammonia (NH3) Sensor

Ammonia (NH3) sensor

Overview

The Ammonia (NH3) sensor is an exhaust sensor providing direct measurement of ammonia for Selective Catalytic Reduction (SCR) dosing control and On-Board diagnostics.

The sensor output can be used to provide feedback to the SCR system helping higher engine-out NOx calibration for improved fuel economy.

Features / Benefits

  • Enables closed-loop urea closing control for optimized NOx reduction efficiency in SCR systems
  • 0-100 ppm ammonia concentration measurement range
  • Sensor electrical OBD included in the sensor electronics

Oxygen (O2) Sensors

Oxygen sensor

Overview

The Oxygen (O2) sensor, or lambda sensor, measures oxygen in a vehicle's exhaust. It is responsible for maintaining a balance between air and fuel for optimal emissions. Too much fuel produces hydrocarbons and carbon monoxide. Too little fuel produces nitrogen-oxide pollutants.

Our New Gen2 oxygen sensors are the smallest and lightest on the market, allowing for greater packaging flexibility. They also deliver the industry’s fastest light-off time - for quicker, closed-loop, control activation.

Features / Benefits

  • Smallest and lightest oxygen sensors on the market
  • Fast light-off time for closed loop emissions control during cold start
  • Dual-layer protection shield and special coating protects from contaminants and water shock with no heater delay at cold start
  • Stainless steel housing tested up to 15 years/150,000 miles for durability and environmental compliance

Particulate Matter (PM) Sensors

Particulate Matter (PM) sensor

Overview

The Particulate Matter (PM) sensor is an exhaust sensor which measures cumulative particulate mass used for on-board diagnostics (OBD) and helps detect leakage in the diesel particulate filter (DPF).

The integrated heater maximizes sensor regeneration across a wide range of operating conditions.

Features / Benefits

  • Compact sensor design
  • Fast response time
  • Equipped RTD (Resistive Temperature Device) element
  • Allows for closed loop heater control for accurate sensor regeneration
  • Plausibility diagnostics capable
