IN 2011,
Volvo was one of the first diesel engine manufacturers to receive stage 3B and Tier
4i certificates for its entire engine line-up. Later, the Volvo Penta 13L Tier 4i diesel engines were
the first engines to be certified by the United States Mine Safety and Health Administration
(MSHA) and the Canada Centre for Mineral and Energy Technology – Mining and Mineral
Sciences Laboratories (CANMET-MMSL).
A full range
With its new extended – and completed – range of engines for mining applications Volvo
Penta has made it easier for manufacturers of machines and vehicles for mining. Now, no one
has to dig any deeper to find a perfect Volvo Penta engine match for any given installation.
All in all the new engine line-up consists of 18 engine variants, nine certified for Tier 2 and nine
certified for Tier 4i. The Tier 2 engines are the TAD 941/1340/1341/1342/1343/1344VE-series
ranging from 300 to 479hp and the TAD1640/1641/1642VE-B-series which ranges between
551 and 700hp.
Outstanding ventilation rates
A major part of total costs in underground mining is ventilation of the mine. This fact is cause
enough for manufacturers and mining operators to pay close attention to the remaining nine
Volvo Penta Tier 4i engines in the new range. With a ventilation rate of around 30 CFM/hp,
they deliver the maximum ventilation rate available for a conventional diesel engine. In other
words: it doesn’t get any better.
The Tier 4i engines in the new range are the TAD1360/1361/1362/1363/1364/1365VE-series
going from 348 to 551hp and the TAD1660/1661/1662VE-series between 551 and 70hp. All
these Volvo Penta Tier 4i engines are equipped with a SCR (Selective Catalytic Reduction) unit.
Selective Catalytic Reduction
The SCR technology is the choice Volvo Penta has made to comply with current and future
emission legislation. Since Volvo Penta introduced its first SCR engines in 2006, the benefits for
users have been increased power and lower fuel consumption – by five to10% compared with
corresponding engines. And, since the catalytic converter was designed to last the life of the
engine, Volvo Penta SCR systems haven’t demanded an increase in service intervals, or caused
any additional downtime.
The SCR system is based on high-efficiency combustion that reduces fuel consumption and
results in low levels of particulate matter (PM), and in high levels of nitrogen oxides (NOx).
The exhaust NOx is converted into harmless nitrogen gas and water vapour. This is made
possibleby the SCR system which automatically injects up to 5% AdBlue
®
, a diesel exhaust
fluid, to the exhaust gases. The gases are then passed through a catalytic converter before
they are emitted to the environment. The extremely low levels of particulate matter in the
emissions make exhaust gas filtration (DPF) unnecessary.
Volvo Penta’s
extended
range of
engines
for mining
Above:
The new Volvo Penta engine range for
mining applications provide outstanding
ventilation rates.
With the introduction of a
number of new engine variants,
Volvo Penta can now offer the
mining industry a complete
range of engines approved for
underground mining applications.
The selection of nine Tier 2
engines and nine Tier 4i engines
– which provide outstanding
ventilation rates – enable
manufacturers and users of
mining equipment to make the
perfect Volvo Penta engine choice.
