"The European Commission has pledged, however, to create a legal route for sales of new cars that only run on e-fuels to continue after 2035, after Germany demanded this exemption from the ban."
How would someone build an engine that explicitly only run on ethanol and which would reject any mixture which contains gasoline, such as E85.
- HPsquared 4y agoThe same way they control other emissions: locked-down software in the engine control system. Possible, though often illegal, to circumvent. Edit: the software can detect if the engine is running on ethanol or gasoline (or mixed) by looking at the air/fuel ratio, which is set using the oxygen sensor in the exhaust. It's called flex-fuel. Quite simple for the software to only allow operation on pure ethanol.
