• Reduce our dependence on fossil fuels
• Reduce the CO2 emission (less greenhouse effect)
• Focus on renewable energy sourced fuels
• Use of oxygen-containing fuels & Biodiesel that are more aggressive
���� Ethanol
� E6 & E85 in favor in California, E10 & E85 in rest of USA
� E10 in Europe, India and China
���� Oxygenates
� MTBE has been legislated out in the USA, but still used in Europe
� ETBE and Methanol as well
���� Biodiesel (B5 to B20)
� Improves diesel fuel emissions
� bio-degradable and non-toxic product
� Reduces diesel engine wear (inherent lubricity of FAME’s)

Explosive
Decompression
Explosive Decompression (ED), also known as Rapid Gas Decompression
(RGD), is structural failure in the form of blistering, internal cracking and/or splitting
caused when the gas pressure to which the seal is exposed is reduced faster than the
gas can diffuse out of the part. This causes internal stresses in the part that can
exceed the physical strength limits of the elastomer.
Rapid Gas Decompression
Testing in 100% CO2 environment may be done in our lab at ETC Meyrin, Geneva
