Volvo Penta at Bauma 2013: A new, exciting Start/Stop function – and an update of the coming Tier 4 Final engine range

When the doors to Bauma 2013 will open on 15 April, Volvo Penta is ready for an exciting follow-up of the new Tier 4 Final engine range and for displaying engine features like the Start/Stop function – the latest Volvo Penta innovation that will help operators to significantly reduce their fuel costs.

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 NO_x – 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.
