I meant ethanol as one of the substitutes for lead (previously a common additive) in gasoline which was often used before to better control compression and combustion. Are microplastics or plastics used to better control combusion engines now?
- XorNot 6y agoI meant ethanol was not substituted for lead AFAIK - the lead was replaced with MTBE in practice, and then the story of ethanol blending has more to do with CO2 emissions reduction (or in the case of Australia, a conservative prime minister somehow getting away with a levy on milk to bail out his mate's ethanol plant and mandating 10% blending in fuel at the pumps). Ethanol was the original anti knock agent, but afaik was actually replaced by tetraethyl lead originally.
- Frost1x 6y agoInteresting, thanks.
