Volvo Penta Helps Oems Meet Their Toughest Environmental Challenge

Press Information

Volvo Penta helps OEMs meet their toughest environmental challenge.

In 2014, manufacturers of off-road original equipment will face a major challenge.
Will their products be ready and competitive when the much stricter Tier 4 Final/Stage 4 environmental standards come into force? For customers of Volvo Penta, the demanding journey towards 2014 will be more like a walk in the park: Volvo Penta will keep it simple – for the OEMs.

Within less than 3 years, the off-road equipment industry must go from Tier 4 Interim/Stage 3B to Tier 4 Final/Stage 4. This means a massive 80% reduction of the NOx – from 2.0 g/kWh to 0.4 g/kWh. It also means a huge challenge to the manufacturers regarding the re-design of their machines for installing new engines and after-treatment systems from their suppliers – provided they’re not customers of Volvo Penta.

Volvo Penta will keep it simple

On 1 January, 2011, Volvo Penta introduced its range of engines compliant with Tier 4 Interim/Stage 3B. This solution was based on the Selective Catalytic Reduction (SCR) technology. For 2014, we will meet the much more stringent Tier 4 Final standards using the same well-tested and proven technology. A further development of the SCR catalyst has improved the NOx conversion to levels unheard of just a few years ago. Adding a “light” EGR system to the engines provides further emission reduction and will at the same time help keep the SCR catalyst operating at an optimal temperature.

The innovative EGR system on the engines is lightly cooled or not cooled at all. This serves two purposes: First of all, it will not add extra cooling requirements to the existing cooling system. Secondly, it will not be subject to exhaust gas condensation and thus the potential corrosion that can lead to downtime.

By avoiding a costly Diesel Oxidation Catalyst (DOC), installation is greatly simplified.

“This is probably the best EGR system in the world”, says David Hanngren, Manager Product Planning Industrial at Volvo Penta, and adds:

“With our new Tier 4 Final engine range, we will also 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.”

A whole new engine range

The new Volvo Penta 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 engines in the range will be ready for delivery in 2014, but they will be on display – and ready
for the OEM’s drawing-boards – at the Intermat exhibition in Paris, in April, 2012:

D5 is a completely new Volvo Penta design. It’s a 5-litre, 4-cylinder, 105-160 kW engine with a
max torque of 900 Nm.

D8 is also an entirely new Volvo Penta design. This is an 8-litre, 6-cylinder, 160-235 kW engine
with a max torque of 1,300 Nm.

D11 is a new version of a proven Volvo Penta design. This 11-litre, 6-cylinder, 235-285 kW engine has a max torque of 1,950 Nm.

D13 is a powerful 13-litre, 6-cylinder, 285-405 kW engine with a max torque of 2,650 Nm.

D16 is the most powerful engine in the range. This 16-litre, 6-cylinder, 405-565 kW engine has
a max torque of 3,200 Nm.

For the present, all engine data is preliminary.

Uptime is king

Volvo Penta supplies equipment manufacturers all over the world with high-performance engines and power systems – but that is just one part of the deal. For the OEM and, not least, the end user, Volvo Penta’s service and support network is as important as product performance, because when it comes to product qualities, uptime is king.

The fact that these engines are developed, manufactured and serviced by one company is vital for the overall performance of every application. Volvo Penta’s continuously expanding service network – currently close to 700 dedicated Industrial service dealers – is therefore a vital part of these products. With service agreements, scheduled maintenance and preventive repairs, we help customers optimise machine uptime even further. No product benefit can compensate for downtime.

Focus on the environment and selected segments

With environmental care as one of the Volvo Group’s core values, the environmental focus comes natural to Volvo Penta. We have been well ahead when it comes to meeting new, tougher emission regulations. This is once again emphasised with the new Tier 4 Final engine range for 2014.

Over the years, Volvo Penta has served a large number of industries with engines and power systems – and will continue to do so. Now, the aim is to increase focus on the Electric Power Generation segment and the off-road segments Materials handling, Construction and Raw material exploration.

THE SCR SYSTEM

The SCR (Selective Catalytic Reduction) 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). Here, the smartness of the system is revealed: 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 it is emitted to the environment. The extremely low levels of particulate matter in the emissions also make exhaust gas filtration (DPF) unnecessary.

AdBlue® is a registered trademark of the Verband der Automobilindustrie e.V. (VDA ).
