A diesel particulate filter is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine
What is AdBlue?
One of the latest techniques used to clean up diesel emissions is known as selective catalytic reduction (SCR). A solution of urea in water is used to treat exhaust gases and remove harmful pollutants,
The fluid used in most vehicles is known as AdBlue.
The EGR system works by recirculating exhaust gases back into the engine in order to lower cylinder temperatures and NOx emissions. The EGR pressure feedback sensor or Delta Pressure Feedback Sensor, detects the pressure changes in the EGR system.
