This one may be a bit tougher:
The search to replace ZDDP has benn ongoing for many years now since it was postulated that the compounds in ZDDP poison catalytic converters.
Much research on these new liquids shows promise as a replacement for ZDDP and other organo-metallic compounds.
Any time you reduce the organo-metallic content of an engine lubricant, you reduce metallic ash deposits on valves and other components.
This new compound is an oil-miscible trihexyltetra-ecylphosphonium bis(2-ethylhexyl)phosphate.
In Ring-on-Liner tests in a base oil with the same concentration as ZDDP, this liquid showed a maximum COF of 0.075 whereas the ZDDP mixture showed a COF of 0.215, a huge reduction in COF.
This liquid showed a 50% reduction in wear when tested against the ZDDP mixture at 100C.
This liquid was stable up to about 300C.
What are the functional name(s) of this liquid, and what is the professional designation for this new liquid?
Guidelines for the Question of the Day:
1. No Piston Cup Lapel Pin will be awarded to the same person within 14 days of a previous award.
2. Please respond with a complete sentence.
3. Please do not post links. If a question arises as to the need for clarification, then sources and links may be requested.
4. Please, no off topic posts.
Functional names for additive components are listed here:
Antifoamant or foam inhibitor
Antioxidant or oxidation inhibitor
Anti-Wear
Extreme Pressure Additive
Demulsifier
Detergent
Dispersant
Emulsifier
Friction Modifier
Metal Deactivator
