Abstract
Additivation of fuels is gaining more and more importance and is recognized as one of the three components with engines technology and fuels quality to help achieve the stringent requirements corresponding to permanently adapted regulations.
The Laboratory PPMV from the Belgian Ministry of Defence has been involved for years in activities conducted as well by the Military Authorities as the Legislators and the Industrial partners. Different programs have been and are conducted on the influence of additives for fuels. Addressing different concerns linked to the use of engines, the following fields have been examined;
- Single Fuel Concept;
- Use of acetals in fuels;
- Possibilities of FAME
- ..
In this paper, results will be presented on the feasability of the Single Fuel Concept (SFC). It is a military concept aiming at the use of jet fuels in diesel engines. The potentials of that approach are reducing the logistic burden but it also offers advantages on different issues like engine cleanliness and environmental contribution.
As a consequence of the growing attention for replacement fuels, the Laboratory is also looking at the potential offered by acetals and FAME as fuels or fuels extenders. Different aspects interesting the producer as well as the use of engines will be approached;
- performance of the engines;
- influence on the emissions;
- durability and cleanliness.
One of the present research programs is looking at the improvements which could be achieved with a system introducing on a strictly controlled manner rare earths and water at the air inlet of diesel engines. Initial results on the emissions (gaseous and particulates) will be presented as well as the future developments of the program.
