asked the Minister of Transport whether he has made arrangements for the test of the latest United States lorry exhaust purifier; and what plans he has for dealing with this problem in England and Wales.

I understand that the United States authorities are urging on American motor manufacturers certain devices to prevent the escape from the crankcase of unburned hydro-carbons which leak past the pistons. It may be that it is these that my hon. Friend has in mind. They do nothing to purify or suppress exhaust fumes, and have in fact been fitted to most petrol engined vehicles manufactured in this country since the nineteen-thirties. It is more difficult to adapt them to diesel engined vehicles, and fewer are so fitted. The police and our technical officers do all they can to enforce the existing law throughout the country; new regulations to prohibit the use of the excess fuel device while vehicles are in motion come into effect on 1st January next.
