FPT Industrial leads project for alternative fuel for heavy-duty engines
Being more sustainable is one of the strategic objectives that FPT Industrial is aiming for. To meet European CO2 emission targets in 2025 and 2030, the use of alternative fuels and e-fuels is essential. Because of this, FPT is now developing a way to use DME (Dimethyl-ether).
Suitable fuel for compression ignition engines and produced from several renewable sources, its chemical properties allow for very low NOx and particle emissions, whilst maintaining high engine efficiency. There are, however, some challenges in the use of DME as a fuel, particularly in terms of the fuel injection equipment.
DME has been industrially used for decades, mainly as a propellant in aerosol cans as it is non toxic and odourless. From a storage and refuelling perspective, DME is like LPG. It is liquid at very moderate pressure levels.
The overall goal of the project is to advance the understanding of using DME as an alternative to diesel in the industrial goods sector and demonstrate clean combustion at comparable efficiency levels. Since DME combustion produces practically no particle emissions, a comparably simple SCR system without the need for a particle filter may be enough to comply with strict emission standards.
Experimental data is showing promising results in terms of CO2 reduction, along with very low NOx and particle emissions, together with similar engine efficiency to diesel.
