Scania EU Stage V - a proven and fuel-efficient solution


The EU Stage V engine range from Scania not only fulfils legislation demands in terms of emission levels, but does so with a lowered fuel consumption that minimises both operating cost and environmental impact.

In the spring of 2016 Scania first showcased its solution for the EU Stage V emissions standard, well in advance of the legislation taking effect in 2019.


The range, consisting of 9- and 13-litre in-line and 16-litre V8 engines, is offered at power output levels of 202-566 kW (275-770hp) for industrial applications and 222-528 kW (250-605 kVA) for power generation applications. 


In addition to lowering fuel consumption by up to 5 % for industrial applications (compared to the EU Stage IV solution) and by up to 9 % for power generation applications (compared to the EU Stage IIIA solution), the EU Stage V engine range also offers impressive torque and engine response, making it more agile in terms of performance.


Scania has carefully overseen all strategic steps from engine design and development to assembly, with the development of the engine-management, fuel-injection and emission-control systems, all having been carried out in-house. 


The technical solution is based on Scania´s Euro 6 solution and uses a diesel oxidation catalyst, a selective catalytic reduction unit, and a diesel particulate filter. Because the solution has already been proven, it guarantees high reliability that is further reinforced via traditional Scania strengths such as product quality, parts availability, a comprehensive support network and equipment uptime. For customers, this means higher machine uptime and, in the end, increased revenues.

The key to success

Development of Scania’s EU Stage V solution used computer simulation and other testing to establish which concepts were the most effective. The concepts were assessed according to five main criteria: handling of exhaust emissions, performance and response, fuel efficiency, cost, and engine lifetime.


Thermo management entails keeping the temperature at an optimal level in the aftertreatment system, regardless of the surrounding and operating conditions, while transient response is about how well and how fast the engine builds torque.


The key to success has been the integration of the throttle handling with the variable-geometry turbo (VGT) control strategies, which also works as an exhaust brake. 


Construction equipment manufacturer Doosan, with which Scania has a long-standing cooperation, is one of the companies that have been involved in the field trials to validate engine hardware, software, and calibration. For example, Doosan have tested Scania’s 9-litre 5-cylinder Scania engine, as well as the 13-litre 6-cylinder engine. 

In terms of machine design and engine installation, existing customers can expect an uncomplicated installation due to the fact that the platform and footprint remain unchanged from the EU Stage IV solution. Further, the DOC and DPF are built in a common container with flexible brackets and the ducts for exhaust in-and outlets can be rotated 360 degrees in order to facilitate the installation process. As always, Scania offers support from application engineers during the design and installation phases.

Product range

Scania’s EU Stage V-compliant engines span from the 9-litre 5-cylinder and 13-litre 6-cylinder inline engines to the 16-litre V8 engine, covering output ranges from 202 kW to 566 kW.


The main components required for the exhaust gas aftertreatment system are: an oxidation converter to cope with HC and CO emissions; a particulate filter to keep the emissions of particulate matter within the legal limits; and an SCR converter to handle NOx emissions – including urea injectors and an evaporator.
