in your series "Black Smoke: Causes and Cures ". But surely, everybody seems to have missed the point, that is pollution of the atmosphere. It is no possible use blaming operators, or garages, the answer should come from the manufacturers.
In this day and age, if my wife (the operator) polluted the house by sweeping carpets with a broom, would I reprimand her, and suggest using damp tea-leaveS, salt, or the other old fashioned remedies—no, I think the answer would lie in my providing her with a vacuum cleaner.
Why then, could not a cylinder, identical to a vacuum cleaner be housed to the rear and as close as possible to the exhaust tail pipe. A non-return valve could be fitted into the neck of the container to allow entry only. The container could have a filter impregnated so as to hold filth from the exhaust, this to be changed frequently. If, after this has been fitted, any vehicle is seen giving off foul smoke, then the operator could be fined, and the vehicle taken off the road.
I have maintained this to quite a few papers and magazines in the past 10 years and I can only assume that they have just laughed at me. But surely the answer must lie in a filter of some sort, if only for the reason that a diesel engine cannot be 100 per cent perfect for its long life on the roads.
