HC Deb 28 February 1973 vol 851 cc365-6W
Mr. David Price

asked the Secretary of State for the Environment what research work he is sponsoring into the use of after-burners and of controlled injec- tion in internal combustion engines for the purpose of reducing the atmospheric pollution caused by motor vehicles; and on current information what economic penalty would have to be paid for their intrdouction into current types of vehicles.

Mr. Peyton

Extensive research is being carried out by industry. My Department has a continuing programme for the evaluation of equipment developed as a result of this research. The use of after-burners and associated equipment might add £300 to the cost of a vehicle.
