OPTIMIZING AUTOMOTIVE LPG BLEND FOR MEXICO CITY

Tests were conducted on 3 representative vehicles of the Mexico City liquefied petroleum gas fleet (LPG), using different propane/butane mixtures. Exhaust emissions, individual hydrocarbon speciation, and ozone forming potential were evaluated to establish an LPG specification for automotive use in Mexico City. Results indicated that a change in composition from 60 to 85% propane in volume had a great effect on CO and NO sub(x) emissions, but only a small one on total hydrocarbons. Mixtures having 70% volume of propane with variations no greater than 4% seem to be the best value, from the point of view of reduction in pollutants.
