Bosch adblue pre heater Kit F01C600244

An AdBlue preheater in a car is a component designed to heat the AdBlue fluid before it enters the selective catalytic reduction (SCR) system. AdBlue is a liquid solution made of urea and deionized water that is used in diesel engines equipped with SCR technology to reduce harmful nitrogen oxide (NOx) emissions. The preheater ensures that the AdBlue fluid reaches the optimal temperature range before it is injected into the exhaust system.

The AdBlue preheater plays a crucial role in maintaining the effectiveness of the SCR system. When the engine is cold, the AdBlue fluid can freeze or become too viscous, which can disrupt its flow and lead to inconsistent emissions reduction. The preheater warms up the AdBlue fluid, preventing freezing and ensuring it remains in a consistent form, ready to react with the NOx emissions in the exhaust gases. By preheating the AdBlue fluid, the preheater ensures that the SCR system can operate efficiently and effectively in reducing harmful pollutants emitted by the diesel engine.
