§ Mr. Leigh
Responsibility for the subject of the question has been delegated to Warren Spring Laboratory under its chief executive, Dr. Cormack. I have asked him to arrange for a reply to be given.
Letter from Doug Cormack to Ms Joan Walley, dated 21 April 1993:Your written Parliamentary Question to ask the President of the Board of Trade what results have been achieved by Warren Spring Laboratory in tests of on-line fuel conditioning devices based on tin alloys or magnetic cones: and whether he will issue guidance on the effectiveness of such products in reducing energy use.As your question relates to operational activities at Warren Spring Laboratory I have been asked to reply.Over the past twelve months or so Warren Spring Laboratory has continued to be contracted by the motor vehicle industry to test and assess modifications to motor car designs in respect of fuel consumption and vehicle emissions., I regret that, as this work has been undertaken on a commercial-in-confidence basis, it is not possible for me to publicise the results. I do, however, enclose some background information about the work of our vehicle emissions team. You would be most welcome to visit Warren Spring Laboratory to meet the team and to see the facilities that we use in testing and assessing vehicle emissions.
