With our Stage V technology, meeting tougher emission standards, we are taking a big step forward towards a more sustainable tomorrow. As input to our Stage V solution, we have listened to our customers to understand their future needs as well as leveraged experience from across the Volvo Group. The result is a new solution designed especially for the Stage V legislation – and for meeting the future needs of our customers’ off-road applications.
Our approach to Stage V follows the Volvo Penta philosophy to design a system with ease in mind – ease of installation, operation and maintenance – and offer a concept adapted to our customers’ working environments. What is more, a system that is optimized for enhanced fuel efficiency and reduced emission levels benefits both customers and the environment.
Watch the clip where Johan Carlsson, Senior Vice President & CTO Volvo Penta, explains the thinking behind the Stage V concept >>
In Volvo Penta’s Stage V concept, the engine and exhaust aftertreatment system (EATS) work in perfect harmony to deliver performance to match customer needs while meeting upcoming emission standards. The high efficiency of the aftertreatment system allows for low engine complexity – the end result is that the technology across the Stage V range is optimized for ease of operation.

Common rail injection system > low noise levels and reduced fuel consumption
Fixed geometry turbo > reduced complexity, improved efficiency, lower fuel consumption
All heat mode devices on the engine > Volvo Penta has selected to use an air inlet throttle, uncooled exhaust gas recirculation (EGR) and an electrical exhaust pressure governor (EPG) for highly effective heat management of the engine. All three heat mode devices work together to enable maximized efficiency of the exhaust aftertreatment and thereby deliver maximized uptime, fuel efficiency and low cooling requirements.
Maximized passive regeneration during normal operation > maximized uptime for the customer
No high temperature regeneration > due to the fact that no sulfur regeneration in the Selective Catalytic Reduction (SCR) catalyst is required> only soot regeneration needed to clean the diesel particulate filter
Volvo Penta’s Stage V engine and EATS are designed to work together to maximize passive regeneration during normal operation. The engine-mounted heat management devices will automatically maintain the exhaust temperature at an optimum level.
The aftertreatment system is flexible – easy to install, operate and maintain. The modular approach ensures that the system can be installed in a number of different configurations and positions.
Here is how it works. Watch the film>>
The aftertreatment system includes the following components:
The Stage V line-up includes all five engines – D5, D8, D11, D13 and D16 – offering the same power range from 105 to 565 kW (143-770 hp) as Volvo Penta’s existing offer for industrial, off-road applications. The new Stage V range ensures installation commonality between different emission levels. The engine program will be consistent, from Stage II to Stage V, which is hugely beneficial for OEMs. Thanks to the compatibility with earlier emission legislations, customers can integrate solutions from across emission stages minimizing the need for re-engineering.
