exhaust treatment - Product overview
What is Exhaust Gas Recirculation (EGR)?
Your NEW HOLLAND machine is equipped with additional components to comply with national and local exhaust
emissions requirements. EGR works by recirculating a portion of the engine exhaust gasses back into the engine
combustion chamber to lower combustion temperatures.
The main components of the EGR system include:
• EGR valve
• Diesel Particulate Filter (DPF)
• Diesel Oxidation Catalyst (DOC)
• Exhaust gas temperature sensors
• Differential pressure sensor
• Throttle valve actuator
What is a Diesel Particulate Filter (DPF)?
A Diesel Particulate Filter (DPF) is a filter mounted in the exhaust stream. During normal operating conditions, the
exhaust gasses pass through the porous walls of the DPF and trap Particulate Matter (PM) generated by the com-
bustion process of the engine. When channels inside the (DPF) fill up with (PM), the system must be cleaned. The
cleaning process is called regeneration.
How does the regeneration process work?
When the (DPF) becomes restricted, the system will need to be cleaned or regenerated by raising exhaust temper-
atures to burn off the trapped Particulate Matter (PM). This process is usually done automatically. Burned PM will
leave behind traces of ash within the (DPF). The ash must be cleaned out by a NEW HOLLAND dealer outfitted with
machines specifically designed to clean (DPF) systems. See the [**Link to maintenance chart**] for service intervals.
Automatic regeneration
When the DPF enters automatic regeneration mode, the display will indicate "DPF ON". Several conditions need to
be followed to properly let the machine perform this function.
• During this mode do not idle or shut the machine down.
• Hot exhaust gasses will be generated. Use in a well ventilated area away from combustible materials.
• Use the machine under normal work scenarios until the automatic regeneration process has completed.
