JCB has brought together ultrahigh
injection pressures of
2,000 bar in the common rail
system, with variable geometry
turbocharging for rapid response
at low rpm, to create a cleaner
more efficient burn. Cooled
exhaust gas recirculation is used
to further reduce emissions,
passing a small amount of the
exhaust gas back through the
engine to cool the combustion
process and reduce Nitrogen
Oxides (NOx) within the cylinder.
However it will be possible
for JCB dealers to recalibrate
the Ecomax engine for use
in less emissions sensitive
territories when sold on the
used equipment market. This
whole life approach to the engine
ensures that JCB equipment
will retain its maximum residual
value, wherever its second
use may be and whatever the
requirements of the markets in
which it may be put to work.
Service
advantages
All Stage IIIB/Tier 4 Interim
engines must run on ultralow
sulphur fuels, and care of
those fuels, to ensure perfect
cleanliness, will be essential to
the smooth running of Stage IIIB
machinery. There will be upgraded
fuel and air filters for Ecomax
engines, plus the Stage IIIB
engines will require a 5 micron
water separator and fuel filter for
the fuel supply line to supplement
the 2 micron engine filter. In
addition a crankcase ventilation
filter must be used, which will
require replacement at 1,500 hour
intervals. JCB Ecomax engines
will however be able to run
on standard engine oils, unlike
engines with after treatment,
which require a more expensive
CJ4 oil to function correctly.

Service costs will not rise
substantially and the Stage IIIB
engines have the same 500
hour service intervals as the
previous models. JCB says that
a typical basket of filters for a
Stage IIIB backhoe loader should
cost around £133, compared to
£90 for a Stage IIIA model. That
relates to an additional cost of
just 3p per hour over a typical
6,000 hour ownership period for
that backhoe loader, an amount
that will be easily offset by the
fuel economy and productivity
benefits of the Stage IIIB engine.
Electronic
Control
Benefits
As the Ecomax engines feature
electronic control, JCB has been
able to fully integrate engine
diagnostics and analysis into
its LiveLink telematic system.
Until now customers have
been able to access location
Bamford's Petrol or Paraffin Engine from 1939. Model Horizontal Petrol, 4hp No 21640
information, service alerts,
engine health alerts and other
critical data, but have not had
full interrogation of the engine.
With the Stage IIIB/Tier 4 Interim
engine LiveLink will provide
improved diagnostics, fuel
economy and work related
data, such as fuel economy in
different working modes. This will
allow customers to more closely
manage the use of equipment,
ensuring that maximum
economy is achieved on site.
JCB is also able to offer ECU
pairing, whereby a machine’s
electronic control unit can be
paired with the LiveLink ECU. In
the event of the LiveLink unit
being removed or disabled, the
machine’s ECU would immobilise
the machine, preventing theft.
Remote PIN management is
an additional benefit, allowing
customers to assign different
PIN codes to different drivers,
or in the case of a hire firm,

customers remotely. This would
prevent a machine that has
been off-hired being used by
non-authorised operators.
“JCB’s investment in engine
technology has resulted in a
market-leading range of engines
that provide increased power
and torque, lower down the rpm
range, yet use less fuel and create
fewer emissions,” said Mr Tolley.
“We have been able to provide
our customers with a solution
to comply with European and
American emissions legislation,
without expensive after treatment
or additives, through the use on
innovative British engineering.
Of course there will be an
additional cost for Stage IIIB/
Tier 4 Interim engines, as they
use sophisticated components
and technologies. However we
feel that the fuel savings and
productivity benefits of the latest
JCB machines will more than
outweigh that initial premium.”
