摘要 |
The present invention provides a method for decreasing the vapour pressure of a gasoline composition comprising admixing with a gasoline base fuel, from 0.5 to 30 vol. %, based on the overall gasoline composition, of ethyl valerate. The present invention further provides a gasoline composition comprising a gasoline base fuel, from 0.5 to 30 vol. %, based on the overall gasoline composition, of ethyl valerate, and from 0.1 to 10 vol. %, based on the overall gasoline composition, of a C3-4 hydrocarbon component, and a method for controlling the vapour pressure of a gasoline composition comprising admixing with a gasoline base fuel, from 0.5 to 30 vol. %, based on the overall gasoline composition, of ethyl valerate, and from 0.1 to 10 vol. %, based on the overall gasoline composition, of a C3-4 hydrocarbon component. The present invention further provides a method of operating a spark-ignition internal combustion engine, which method involves introducing into a combustion chamber of the engine a gasoline composition of the present invention. |
