The story of the Tier 4 Final engines started in January, 2011, when Volvo Penta introduced its range of engines compliant with Tier 4 Interim/Stage 3B – all based on the Selective Catalytic Reduction (SCR) technology. They were well received by the market. But the off-road equipment industry were also well aware that within less than 3 years they had to go from the Interim stage to the Final stage – a substantial 80% reduction of the NOx – from 2.0 g/kWh to 0.4 g/kWh. They were also facing the additional challenge of re-designing their machines for installing new engines and after-treatment systems from their suppliers. Revolutionising
Volvo Penta chose to keep it simple
To meet the new, stringent emission requirements of Tier 4 Final, Volvo Penta soon found that the well-tested and well-proven SCR technology was superior. Apart from meeting all the new emission standards, it would make life easier for all the equipment manufacturers already employing this technology.
David Hanngren, Manager Product Planning Industrial at Volvo Penta, explains: “With our new Tier 4 Final engine range, we will meet our customers’ primary objectives: no re-generation, limited installation challenges, continuous optimised fuel consumption and low operating costs. With as few and as simple changes as possible, we aim to make our customers’ job as easy as possible”, and adds: “This is probably the best EGR system in the world”.
The “light” EGR system added to the engines has provided further emission reduction. It will, at the same time, help keep the SCR catalyst operating at an optimal temperature. By avoiding a costly Diesel Oxidation Catalyst (DOC), installation is greatly simplified.
A new, solid engine range
The Volvo Penta Tier 4 Final engine range for off-road applications consists of five basic engines. Thanks to the SCR system it has been possible to meet the new emission standards with only a limited number of technical changes. Here, the component commonality of the engines is particularly valuable to OEMs who include several engine sizes in their product applications.
All the engines in the new range will be on display at Bauma 2013, 15–21 April, in Munich. They will also be ready for delivery in 2014 – but already today they are ready for the OEM’s drawing-boards.
More Volvo Penta news at Bauma
At Bauma, Volvo Penta will also introduce the new, automatic Start/Stop Function for industrial equipment. It turns off an idling engine after a pre-set time span, and when the driver activates any machine control the engine starts immediately and the work can continue. This Volvo Penta innovation will help operators to reduce their fuel costs with up to 5%!
Volvo Penta will also launch the new Industrial Extended Coverage, IXC – a programme that allows operators and equipment manufacturers to not only guard themselves from long and costly downtimes in the long term, but also to tailor the agreement in accordance with specific conditions and requirements.
Mining industry people attending Bauma will most certainly focus on Volvo Penta’s new range of engines approved for underground mining applications; nine Tier 2 engines and nine Tier 4i engines with outstanding ventilation rates.
A fourth novelty is the Volvo Penta Oil Analysis – an easily performed analysis that will enable operators to increase the intervals between services from every 500 hours to every 1,000 hours – a massive improvement which will pay off already in the short term.
