New diesel engine boasts low consumption and high efficiency, decreasing emissions of contaminating particles by 80%

11/18/2020 / By Virgilio Marin

European researchers have developed an improved diesel engine that’s more eco-friendly and efficient than current models, paving the way for greener and fuel-efficient vehicles. During a project meeting held in Austria, the researchers said that the new engine uses less fuel and emits 80 percent fewer contaminating particles than the current legal limits.
Developing eco-friendly, efficient diesel engine

The DiePeR project was headed by Austrian automotive firm AVL and received funding from the European Union (EU)’s Horizon 2020 program, a research and innovation initiative. According to project coordinator Jesús Benajes of the Polytechnic University of Valencia (UPV), the objective of DiePeR was to search for the optimal combination of innovative concepts and existing technology in a bid to lessen noxious emissions and improve fuel consumption.

One of the main challenges in achieving this goal is optimizing the functioning of the engine’s components in different driving situations. Co-researcher Jaime Martín, Benajes’ colleague at UPV, explained that the post-treatment systems that lower particulate emissions are very sensitive to the temperature of exhaust gases, which varies considerably when driving in a city or on the motorway.
