Fuel system
Scania’s electronic Engine Management System (EMS) was developed in-house, specifically for our engines. It is designed to stand up to heavy use and harsh conditions and is thus extremely dependable. And it makes a major contribution to cutting fuel consumption and emissions.

The same goes for the Scania XPI injectors, which are at the heart of the most reliable, well-proven fuel injection system on the market. They are designed for tough conditions and can handle fuel of varying quality.

Dual oil filtration system
All Scania engines have a unique oil filtration system that provides maximum filtration and minimum wear. A full-flow paper filter removes large particles while a centrifugal cleaner filters out small particles.

Scania’s oil filtration system remains unchallenged as best-in-class, providing obvious benefits like better operating economy and lower environmental impact.

New emission standards in 2011
Scania offers engines that deliver outstanding operating economy together with the lowest possible environmental impact. In 2011 the stringent emission standards Stage IIIB and Tier 4i will come into force, and when this happens Scania will offer engines that meet these demands. 

Pioneering technology for emission control 
Scania uses two emission control technologies – EGR and SCR – to handle emissions in the most effective way.

With EGR, exhaust gas recirculation, the intake air is diluted with exhaust gases to reduce NOx formation during combustion. With its Euro 5 EGR inline engines, Scania is the first manufacturer in the world to meet Euro 5 standards without exhaust aftertreatment.

SCR, selective catalytic reduction, is an aftertreatment system where a urea solution (AdBlue) is injected into the exhaust flow, causing a catalytic process that reduces NOx. Also the accelerator response is superior to other solutions, which provides for better driveability.

Scania’s legendary V8 engines are equipped with SCR to take driveability and durability to new heights in the high-output segments. Both technologies are part of Scania’s R&D portfolio for future, even tougher, emission standards.

Technology for other fuels
Scania supports the much-needed shift to renewable fuels. This shift can be achieved with existing technology and with fuels that are already available on the market. Scania has delivered trucks and buses with ethanol engines since the late 1980s, and permits its modern engines to run on up to 100% biodiesel (FAME fuel, e.g. RME).  Now our engine customers can benefit from that vast experience.
