<p>The invention is based on a modification to the exhaust system, in which: first, the gases are passed through a filter containing water, which is intended to eliminate the temperature of the exhaust gases; second, the gases are passed through ducts solidly connected to the exhaust manifold in order to eliminate any remaining vapours; and, in a third step, the gases are passed through a metal fibre filter soaked in oil, which is intended to eliminate solid residues and to lower the concentration of pollutants.</p> |
