Diesel and Petrol Engines (Exhaust Fumes)

HC Deb 24 March 1959 vol 602 cc1101-2

14. Mr. Ernest Davies

asked the Parliamentary Secretary to the Ministry of Works, as representing the Lord President of the Council, what research is being carried out in regard to controlling the emission of diesel oil and petrol exhaust fumes from vehicles; and what results have so far been obtained.

Mr. Nicholls

Research on combustion in diesel and petrol engines with a view to reduction in the emission of exhaust fumes is being carried out by the Motor Industry Research Association and the British Internal Combustion Engine Research Association, each of which is supported by the Department of Scientific and Industrial Research. Results of this and other work show that the greater part of the smoke from such engines can be prevented by proper adjustment, running and maintenance. The Warren Spring Laboratory of the Department of Scientific and Industrial Research has tested a catalytic device which reduces the pollution from petrol engine fumes effectively.

Mr. Davies

While I welcome that reply, may I ask whether the Parliamentary Secretary agrees that it indicates that the operators of vehicles are remiss in not controlling the emission of these noxious fumes? Will the Parliamentary Secretary make representations in the right quarters for the more vigorous enforcement of the regulations? The very large amount of fumes which are emitted is a growing menace on the roads.

Mr. Nicholls

Yes. From the personal experience of all of us, it is a fact that in far too many cases proper maintenance has not been carried out, resulting in the emission of unpleasant fumes. I assure the hon. Member that this is well known and that anything that can be done by my noble Friend's Department is being done to ensure that the authorities which can insist upon proper maintenance do so.

Mr. Davies

What is being done? The matter has been raised in the House on several occasions, but no indication has been given of the action which is being taken to reduce this menace on the roads.

Mr. Nicholls

The hon. Member knows that action of this kind is against the law and the authorities for enforcing the law are well known to the hon. Member. I have no doubt that they recognise the importance of the matter. The Questions and Answers which we have in this House from time to time underline not only the importance that the Department attaches to this problem, but the importance which this House attaches to ensuring that action is taken.
