Traces of vanadium in substantial-temperature combustion products and solutions type droplets of molten vanadates. These attack the passivation layers on metals and result in substantial temperature corrosion, and that is a priority specifically for interior combustion engines. Molten sulfate and guide particulates even have these types of outcome. 1970 https://nuso44444.wikievia.com/10388784/the_basic_principles_of_smoke
