KEEPING LEAD IN THE CAR

THIS ARTICLE REVIEWS RECENT PROGRESS IN THE DEVELOPMENT OF A DEVICE, BASED ON FILTRATION PRINCIPLES, WHICH SIGNIFICANTLY REDUCES VEHICLE LEAD EMISSIONS: IN PARTICULAR THE COSTS OF SUCH DEVICES, THEIR LONG TERM DURABILITY AND EFFICIENCY AND THEIR FUTURE POTENTIAL ARE DISCUSSED. THE FILTRATION SYSTEM INVOLVES REPLACING THE NORMAL SOUND ABSORBING MATERIALS IN THE RESONATOR AND SILENCER WITH ALUMINA-COATED STAINLESS STEEL WOOL. IT IS ACCEPTED THAT SUCH SYSTEMS DO REDUCE VEHICLE LEAD EMISSIONS. ASPECTS OF FILTER SYSTEMS AFFECTING (A) THE MOTOR INDUSTRY, WHICH INCLUDE EFFECTS ON VEHICLE PERFORMANCE AND NOISE ABATEMENT AND (B) THE ENVIRONMENTALIST WHICH INCLUDE LONG-TERM RETENTION OF LEAD, ARE DISCUSSED. THE POTENTIAL OF FILTER SYSTEMS HAS NOT BEEN FULLY EXPLOITED AS SOME PROBLEMS MUST FIRST BE SOLVED. THE COST EFFECTIVENESS OF KEEPING LEAD IN THE CAR AND IN PETROL MAKES ECONOMIC SENSE. /TRRL/
