AFTER the public policy committee of the Royal Automobile Club concluded that dense smoke from oilengined vehicles was a serious danger to road users by reducing visibility, R.A.C. and Automobile Association road patrols carried out a survey on 12 hills, with gradients varying between 1 in 10 and 1 in 25. The survey showed that the proportion of vehicles observed to emit dense smoke was sufficient to indicate that the problem was a serious one.
According to a report of the R.A.C. technical and engineering committee released last week, discussions were held with other interested parties, including British Road Services, the London Transport Executive, the National Road Transport Federation and the Public_Transport Association, and it was agreed to set up a special
committee.
This committee attributed the causes of excessive emission of smoke to faulty maintenance and abuse of pump or governor adjustments. Although big operators employed skilled staff to maintain injection equipment, smaller operators could usually obtain outside a.ssistance from contractors, it was stated.
Drivers sometimes tampered with the excess-fuel device to obtain greater engine power. The committee thought that if drivers were made aware of the danger of smoke emission, they would co-operate to overcome it, particularly as they belonged to the Most courteous class of road user.
