How they work

EGTS Scematic B

The exhaust gas temperature sensor (EGTS), which is located in front of Diesel Oxidation Catalyst (DOC) and/or in front of Diesel Particulate Filter (DPF), detects exhaust gas temperature and converts it into a voltage and feedback engine ECU with the voltage signal in order to control engine condition to effectively reduce emission.

With the improved temperature detection performance of EGTS, post injection control and particulate matter loaded amount estimation is enabled in DPF regeneration control, resulting in cleaner emissions, as well as increased fuel efficiency due to less fuel required in the DPF regeneration process. In addition, catalyst deterioration and over heat protection is ensured in catalyst control.
