Volvo Tier 4 Final engine technology
reduces NOx 80 percent
olvo Tier 4 Final technology Volvo launched its Tier 4 Final technology – which
includes its D4, D6, D8, D11, D13 and D16 diesel engines – at ConExpo-Con/
Agg 2014. The engines, which deliver 5-percent fuel savings compared to previ-
ous models, feature selective catalytic reduction (SCR) technology cooled external
exhaust gas recirculation (CEGR) that are designed to reduce NOx levels by 80 per-
cent compared to Tier 4 Interim. The new engines power the company's G Series
articulated haulers, G946C motor grader and H Series wheel l.

BOMAG's vibratory tampers work
for highway patching
BOMAG's new line of vibratory tampers have low-operating
weights and can perform compaction jobs. The vibratory
tampers can be used for highway patching in which a roller
would be too large or for soil or backfi ll compaction in
tight areas. The company offers three models in the new
line: the BT60, BT65 and BVT65. The BT60, designed for
use in confi ned spaces, weighs 128 pounds and delivers
up to 3,372 pounds of impact force, while the BT65, cre-
ated for high-compaction demands, weighs 150 pounds
and delivers 3,822 pounds of impact force. The BVT65 is
designed for occasional use in typical applications, weighs
143 pounds and delivers 3,597 pounds of impact force.
The BT60 has a 9-inch standard operating width, while
the BT65 and BVT65 each have an operating width of 11
inches. Four interchangeable shoe sizes (6, 9, 11 and 13
inches) are available as optional equipment. betterroads.com/

Case 821F, 921F wheel loaders meet
Tier 4 Final standards
Case Construction Equipment's 821F and 921F wheel loaders have been up-
dated to meet Tier 4 Final emission standards. The wheel loaders are equipped
with a selective catalytic reduction (SCR)-only solution that treats emissions
separately with diesel exhaust fl uid (DEF) and does not require the engine to
re-circulate exhaust gas. This, Case says, optimizes combustion and machine
performance, lowers engine temperatures and eliminates maintenance and
downtime associated with fi lter replacement and regeneration.
Each loader has a best-in-class 6.7-liter engine that also provides quick
throttle response and impressive torque. The 821F and 921F wheel loaders
produce 212 and 241 net peak horsepower, respectively.
