§ Mr. Ellis Smith
asked the Parliamentary Secretary to the Ministry of Works, as representing the Lord President of the Council, if the Department of Scientific and Industrial Research will consult engineers employed at firms who manufacture diesel engines on such problems as the prevention of air pollution from diesel engine fumes, the maintenance of diesel engines, the prevention of fumes in underground works by the use of exhaust scrubbers, as in mines; and if he will give the utmost urgency to the study of the application of present methods in minimising this form of air pollution.
§ Mr. H. Nicholls
The Motor Industry Research Association and the British Internal Combustion Engine Research Association, the co-operative industrial research organisations which are supported by the Department of Scientific and Industrial Research, are in close consultation with the designers and engineers of member firms manufacturing diesel engines on problems concerning the reduction of exhaust fumes from such engines. The Warren Spring Laboratory is in touch with firms interested in the problem of minimising pollution by diesel engine exhaust gases and is expediting investigations into the purification of diesel exhaust gases by catalytic afterburning.
