The overall objective of the REWARD (Real World Advanced Technologies for Diesel Engines) project is to develop the know how, intellectual property and technical capabilities to produce cleaner, highly efficient Diesel powertrains and aftertreatment technologies for future light duty vehicles. Growing road traffic in Europe entails detrimental effects on the environment and public health, to a level that is becoming unsustainable, whilst generating a large contribution to climate change. This outcome is in despite of increasingly stringent emission standards being introduced.The challenge is to develop a new generation of engine technologies able to comply with stricter post-Euro-6 emissions limits under real-driving conditions, whilst complying with future legislation on CO2 emissions, air quality and producing significantly less noise.

Customer Benefit

The project addresses a range of vehicle classes: A, B, C, D and E passenger cars and light commercial vehicles (LCVs) up to 3,500 kg. The project is focussing on cost-effective high-volume production solutions that deliver better than Euro 6 limits under Real Driving conditions (EU6 RDE). REWARD is funded through the European Commission’s Horizon 2020 framework and the consortium consists of 16 different partners from 10 European countries.


Holistic approach for the improvement of the engine cycle and combustion


Various technologies, friction and wear reduction measures, exhaust gas aftertreatment concepts, fuel efficient 2-stroke and 4-stroke Diesel engine concepts, will be advanced to TRL 6 or 7 and integrated into three demonstration vehicles. A full calibration and assessment of the vehicles with their underlying technologies will take place to prove the capability for real driving emissions below the upcoming Euro 6 limits, a 25% friction reduction across the entire engine operating range, a significantly higher lifetime durability and a more than 5% improved overall fuel efficiency. The impact of the cost effectiveness and high volume production suitability of the applications will also be demonstrated.  

Ricardo is responsible for vehicle, engine and aftertreatment system simulation, exhaust thermal management simulation and exhaust thermal management experimental results.
