1 - GENERAL INFORMATION

Electro-magnetic compatibility (EMC)

Interference may arise as a result of add-on equipment that may not necessarily meet the required standards. As

such interference can result in serious malfunction of the unit and/or create unsafe situations, you must observe

the following:

• The maximum power of emission equipment (radio, telephones, etc.) must not exceed the limits imposed by the

national authorities of the country where you use the machine

• The electro-magnetic field generated by the add-on system should not exceed 24 V/m at any time and at any lo-

cation in the proximity of electronic components

• The add-on equipment must not interfere with the functioning of the on board electronics

Failure to comply with these rules will render the NEW HOLLAND warranty null and void.

1 - GENERAL INFORMATION

Exhaust Gas Recirculation (EGR) - Diesel Particulate Filter (DPF)

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 Oxidation Catalyst (DOC)

• Particulate Matter Catalyst (PM Cat)

• Exhaust gas temperature sensors

• Throttle valve actuator

What is a Particulate Matter Catalyst (PM Cat)?

A PM Cat is a high efficiency flow through filter that works based on an open flow design to allow exhaust gases to

pass through. It is made up of alternating layers of corrugated metal foil on a porous metal fleece. The filter captures

particulate matter long enough for catalytic oxidation. By design, a PM Cat cannot plug up, creating no risk of an

uncontrolled regeneration.

How does it work?

When exhaust enters the DOC, many chemical reactions occur. Nitric Oxide (NO) gas enters the DOC to be oxidized

to nitrogen dioxide (NO2). When it enters the particulate matter catalyst, NO2 oxidizes the particulate matter, creating

a continuous, efficient, passive regeneration. This reaction occurs best between 220 - 480 °C (428 - 896 °F).

What if the exhaust isn’t warm enough?

A special engine management system has been designed for off road applications to maintain the efficiency of the par-

ticulate matter catalyst, even in situations such as prolonged idling, or low-load applications. During these scenarios,

the engine management software will activate an exhaust temperature management mode to maintain the efficiency

of soot reduction. In this mode, the exhaust gas temperature is controlled via management of multiple injections and

control of the air system. This design enhances passive regeneration in low load conditions, and reduces the need

for an incinerating regeneration.

Manual regeneration

If the thermal management system is disabled for prolonged periods of time, depending on exhaust temperatures, soot

may build up within the particulate matter catalyst. If the soot build-up reaches extreme levels, a manual regeneration

initiated by the operator may be necessary. This is enabled through the instrument cluster, and takes about 15 min.

For these reasons, it is recommended to have the thermal management system remain enabled unless the tractor is

in high fire-risk conditions.

US Environmental Protection Agency (EPA) and California Emissions Control Warranty

Statement

NEW HOLLAND warrants to the ultimate purchaser and each subsequent purchaser that the engine is designed,

built and equipped so as to conform with US Environmental Protection Agency regulations applicable at the time of

1-7

1 - GENERAL INFORMATION

manufacture and that it is free from defects in workmanship or material which would cause it not to meet these

regulations for a period of:

•

2 years or 1500 h of operation, whichever occurs first, for engines less than 19 kW (25 Hp).

•

5 years or 3000 h of operation, whichever occurs first, for engines greater than or equal to 19 kW (25 Hp).

NOTE: This warranty applies to all units operated in the United States or Canada.

Coverage

The model year, class of diesel engine, and emission application determination for your engine are identified on the

Emission Control Information Label. This label is affixed to one of the following areas of the engine: the top of en-

gine's rocker arm cover, the right-hand side of the oil pan, and the right-hand side of the engine front gear cover.

The warranty period begins on the date the new equipment is sold to the first retail purchaser. The presence of the

emission control label is the indication that the engine conforms to the applicable standards. Any emission control

system parts which are proven defective during normal use will be repaired or replaced during the warranty period.

The engine owner has responsibility to perform all the required maintenance listed in the Owner's Manual. NEW

HOLLAND will not deny an emission warranty claim solely because no record of maintenance exists; however, a

claim may be denied if failure to perform maintenance resulted in the failure of a warranted part.

It is recommended that replacement parts used for maintenance or repairs be NEW HOLLAND Service Parts to main-

tain the quality originally designed into your emission certified engine. The use of non- NEW HOLLAND parts does

not invalidate the warranty on other components unless the use of such parts causes damage to warranted parts.

The manufacturer is liable for damages to other engine components caused by the failure of any warranted emission

control system part. NEW HOLLAND is not responsible for failures resulting from improper repair or the use of parts

that are not genuine NEW HOLLAND or NEW HOLLAND approved parts.
