TriMet reports that it has installed exhaust filters on 45 of it’s oldest buses. Combined with the use of cleaner fuel, this reduces particulates and emissions by up to 90%.
This brings the buses up to the standard applied to newer vehicles. TriMet will eventually roll out this technology to the oldest 1/3 of it’s fleet.
Good progress towards removing the “stinky” component of the “stinking and noisy” objection to buses.
