SCR ready for 2011 - Ready for 2011 : Volvo Penta

The 2011 exhaust emission legislation in Europe and US can present major challenges to operators and Original Equipment Manufacturers. Volvo Penta is committed to making this transition as simple as possible by offering engines with:

Low fuel consumption
Easy and compact installation
High power output
Low service requirements

The off-road engine range uses SCR (Selective Catalytic Reduction) technology to comply with 2011 EU stage 3B and EPA Tier 4i emission regulations. The engines also deliver substantial cost savings in both equipment manufacturing and operational use.

Volvo SCR emission systems are already well proven since its introduction in 2006 in high volume applications.

Lower fuel consumption and easier on-site maintenance
High efficiency combustion results in low fuel consumption (5-10% compared to today’s engines) and extremely low levels of particulate matter (PM) – but high levels of nitrogen oxides (NOx). The NOx is converted into harmless nitrogen gas and water vapour by automatically adding up to 5% AdBlue®, to the exhaust gases and then passing this through a catalytic converter.

As the SCR cat is designed to last the life of the engine, there is no increase in service intervals or costly downtime.

Easier installation
The Volvo SCR system has the same (or lower)cooling demand than today. This has the advantage of minimising noise levels and the cost of the radiator package. A smaller radiator also allows OEMs the flexibility to accommodate the cooling system in space sensitive installations.

Maximising power output
Another benefit of turning more energy in the fuel into mechanical power (less heat rejection) is that the power output can be maximised for a given engine displacement. This results in smaller engine sizes, reduced costs and simplified installations.
