HC Deb 09 June 1972 vol 838 cc182-3W
Mr. Carter-Jones

asked the Secretary of State for Trade and Industry if he will outline in the Official Report the proposals and support which his Department is giving to bring existing diesel engines up to the BSAU141A standard of smoke emission; and if he will make a statement.

Mr. Chataway

Diesel engine manufacturers are not expected to encounter difficulties in meeting the BSAU141A standard with which new vehicles must comply from 1st April, 1973, under regulations made recently by my right hon. Friend the Minister for Transport Industries. Existing vehicles are not subject to these new regulations but my right hon. Friend is also considering ways of improving the enforcement of controls over smoke emission from vehicles in use.
