Across the globe, emission standards are tightening for vehicle manufacturers, thus accelerating the need for global engine manufactures to employ additional emission reduction strategies.
Since the majority of emissions are generated during the initial start of engine operation and during extended idle conditions, the addition of an integrated exhaust thermal management system in front of the catalyst enables rapid light-off and efficient NOx conversion through the full range of operating conditions.
The sensor is used in the FCS (Fuel Control Subsystem) of a Cold start Thermal Unit which is using a diesel burner to heat-up the exhaust line upstream the SCR system.
The main function of the Pressure & Temperature Sensor is the exact measurement of the Diesel fuel pressure for optimal quantity calculation and to allow di-agnostic purposes (OBD). Both pressure sensor and combo pressure & temperature sensor are available.
