Outstanding ventilation rates in Volvo Penta’s extended range of engines for mining

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.

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 engine 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 479 hp and the TAD1640/1641/1642VE-B-series which ranges between 551 and 700 hp.

Outstanding ventilation rates

The major part of the 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 551 hp and the TAD1660/1661/1662VE-series between 551 and 700 hp. 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 the users have been increased power and lower fuel consumption – by 5-10% compared with corresponding engines. And since the catalytic converter was designed to last the life of the engine, the Volvo Penta SCR systems haven’t demand any increase in service intervals, or caused any additional downtime.

The SCR system is based on high-efficiency combustion which reduces the fuel consumption and results in extremely low levels of particulate matter (PM), but also in high levels of nitrogen oxides (NOx). The exhaust NOx is converted into harmless nitrogen gas and water vapour. This is made possible thanks to 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 also make exhaust gas filtration (DPF) unnecessary.
