Abstract

A vehicle component includes a surface that is configured to contact a fuel containing ethanol and zinc ions. A sacrificial carbon layer is disposed on the surface. The sacrificial carbon layer has a thickness of greater than or equal to about 250 nm to less than or equal to about 5 μm. The sacrificial carbon layer includes carbon that is configured to complex and solubilize ZnO deposited on the surface, wherein the ZnO forms from the zinc ions carried by the fuel.
