Really? Are you saying Diesel can be run clean in the same way Electric cars can, if no one messes with the engine output?
Particulates, not emissions.
BBC said:However, modern diesels actually emit very few particulates - because they are equipped with special filters.
According to Emissions Analytics chief executive Nick Molden these systems work very well.
His company carries out its own real-world emissions testing - as opposed to the tests used by manufacturers to certify their new vehicles, which until recently were exclusively laboratory-based.
"Modern diesels essentially do not have a particulates problem," he says. "The filters clean up 99% of the particles. So long as they are not tampered with, they are very effective".
