REGULATIONS concerning t h e emission of smoke from vehicles would be reconsidered to discover whether they fulfilled the purpose for which they were framed, said Lord Lloyd, Parliamentary Under-Secretary to the Home Office, in the House of Lords on Tuesday.
Lord Lucas criticized the maintenance of many lorries which emitted clouds of exhaust from their oil engines. "The Diesel engine," he said,." is one of the masterpieces of British automobile engineering and the manufacturers of .these engines take meticulous care to see that the smoke emission may be negligible."
Lorry drivers might tamper with injectors with the mistaken idea that the greater the 'amount of fuel injected the higher would be the power. Lord Lucas praised the level of maintenance of London Transport and other large operators.
Lord Lucas thought that manufacturers should make oil engines proof against tampering, but Lord Teynham doubted whether drivers interfered with injection equipment. A partial remedy might he to fit vertical exhaust pipes. The nuisance had been exaggerated, hut he agreed that, with the increasing use of oil engines, the problem should he examined.
Lord Lloyd said that oil engines annually produced 20,000-40,000 tons of sulphur dioxide out of 5.3m. tons emitted altogether. Hethought that the greater danger of excessive emission of smoke was not unhealthy pollution, but the obscuring of vision on the road.
