off-highway and industrial equipment
markets. The 4JJ, which is used by
several hydraulic excavator manufacturers, has become available for general applications and is suitable for use
in mobile and stationary machinery, the
company said.
The 4JJ engine is an inline four-cylinder diesel available in ratings of 67
and 101 hp for power generation applications and 84 to 130 hp for industrial
applications. The engine has bore and
stroke of 95. 4 mm x 104. 9 mm for an
overall displacement of 3.0 L.
The engine initially debuted in
pickups and cab-forward commercial trucks, and Isuzu has produced
more than 400,000 since its introduction. The industrial engine shares
the block, crankshaft, pistons and
the connecting rods with the truck
engine, providing significant economy of scale benefits, Isuzu said.
The off-highway engine has a different cylinder head and top end, gear
case, flywheel housing and oil pan
arrangement.
The engine incorporates an overhead cam design with four valves
per cylinder and a full-authority common rail fuel injection system with a
compact, cooled EGR system. The
fuel system, supplied by Denso, can
provide up to five injection events and
has all of the capabilities of the typical common rail system, the company
said. All of the engines incorporate
open crankcase breather systems
and engines rated above 100 hp typically include charge-air cooling.
Dimensions of the 4JJ engine in
a standard configuration are 38. 4 in.
long (including fan), 29.09 in. wide and
33. 1 in. high. Dry weight is 705 lb.
According to the company, suitable
mobile applications for the 4JJ diesel include skid-steer loader, ag tractors, wheel loaders, backhoe loaders,
asphalt pavers and directional drills.
Beyond power generation, stationary
applications could include air compressors, dewatering and irrigation pump
sets, and wood chippers.

Emissions Technology
Since its launch in 2004 the JCB
Dieselmax engine has undergone
continual development. More than
150,000 engines are now working in
the field globally, the company said.
The latest developments will see
the Dieselmax engines past the Tier
4 interim/Stage 3b legislation that
will come into effect for engines of
this size in 2012, and JCB said they
are well set for Tier 4 final/Stage 4 in
2014.
JCB said as many engines within
the 75 to 175 hp range are used in a
variety of applications where equipment is operated under variable light
loads, there can be concerns about
DPF regeneration, with the engine
management system having to force
the regeneration process by burning
additional fuel.
To achieve the next round of
emissions regulations, JCB Power
Systems has worked closely with
JCB Ecomax
