Bio methane-powered cars do not create any carbon deposits. This is the result obtained by the first monitoring data collected by BioMethER, a project developed thanks to the collaboration between Iren and Volkswagen Group Italia.
The project allowed to analyze the impact of the direct use of bio methane as a fuel for transportation. The tests were carried out in the test room of the Enea della Casaccia Research Center, equipped with a roller bench, on two new vehicles of the same brand – Volkswagen Polo TGI 1.0 90CV – powered 100% with bio methane produced by sewage sludge in Roncocesi’s Iren demonstration plant (Reggio Emilia).
The results showed that after 15,000 kilometers driven on bio methane there was the total absence of carbon residues on the piston crown, a data that suggests less wear on the engine.
