UNLEADED GASOLINE AND ADVANCED EMISSION STANDARDS. REPORT ON AN EXPERT MEETING IN STOCKHOLM MAY 10-11, 1979

A meeting of experts was called in may 1979 to discuss the use of unleaded petrol and advanced emission standards. The background is that (1) low-lead petrol will be introduced within next 2 years, (2) unleaded petrol will be introduced within 5 years, (3) a report will soon be published concerning the adoption of either ece or us federal emission standards, (4) vehicle inspection system will be made more stringent, and (5) vehicle regulations are to be revised. Talks were given on the use of unleaded petrol, emission standards in relation to health hazards, fuel consumption, type inspection problems, and the views of the petroleum industry on unleaded petrol (drop in octane would mean at least 5% extra consumption). A discussion on emission standards examined the addition of methanol or ethanol to petrol. There would be (1) a need to modify engines, (2) reduction in compression ratio, (3) 3-10% rise in fuel consumption, (4) up to $1000 rise in vehicle costs, (5) 3-4 years lead time. Most existing cars could not use unleaded petrol because of lack of valve seat lubrication. Most would have to be scrapped. Addition of methanol would necessitate use of components resistant to this, would mean 5% rise in consumption, and reduce performance. (TRRL)
