7085804C1 | Genuine International® Aftertreatment Doser Control Unit

Functions: 
Precise Def dosing: The DCU meticulously controls the amount of DEF injected into the exhaust stream. It relies on various engine parameters and sensor inputs to optimize the dosing process.   
Fault detection and diagnosis: The DCU is equipped with advanced diagnostic capabilities. It can detect and report any malfunctions or issues within the aftertreatment system, aiding in timely troubleshooting and repairs.
Sensor monitoring: The DCU continuously monitors a range of sensors, including exhaust temperature, pressure, and flow rate. By analyzing this data, it can adjust the DEF dosing accordingly to maintain optimal performance.   
Communication with engine control module (ECM): The DCU communicates seamlessly with the ECM to coordinate engine operation and aftertreatment system functions. This ensures synchronized and efficient operation of the entire system.

This part, the Aftertreatment Doser Control Unit (DCU), is essential for the optimal functioning of the exhaust aftertreatment system in vehicles. It precisely controls the dosage of DEF (urea solution), which reduces harmful emissions, ensures the efficient operation of the aftertreatment system and reduces the risk of malfunctions. By monitoring sensors and detecting errors, the DCU ensures proper engine operation and helps to detect and repair potential problems in time.
