As explained by DieselNet in the article “Exhaust Gas Temperature Sensors,” exhaust gas temperature (EGT) sensors are essential in today’s internal combustion engines—particularly for monitoring, managing, and protecting exhaust aftertreatment systems. These sensors ensure thermal-sensitive components like turbochargers, diesel particulate filters (DPFs), and selective catalytic reduction (SCR) systems operate safely and efficiently.
Why EGT Sensors Are Critical
In both diesel and petrol engines, knowing the precise temperature of the exhaust gas stream is vital. In diesel engines, DPFs, SCR systems, and NOx adsorber catalysts (NAC/LNT) rely on temperature data to initiate regeneration or chemical reduction processes. In petrol engines, especially those with three-way catalysts (TWC), engine management strategies are built around optimal catalyst temperature ranges.
