AMF - Implementing Agreement on Advanced Motor Fuels

Path: Home| > FUEL INFORMATION| > Fuel comparisons|

Fuel comparisons


Within the IEA-AMF, a number of Annexes devote in different concepts of advanced fuels and engine technologies as presented in the fuel-specific Chapters (short list in Table 1). Broader scope of work has covered, for example, fuel comparisons, standardisation issues, measurement methods and dissemination of information. This work within the IEA-AMF is introduced in Tables 2 and 3.
