| 发明名称 | Method for determining a concentration of alcohol in a fuel mixture | ||
| 摘要 | A method for determining a concentration of alcohol in a fuel mixture, where a characteristic curve for a parameter describing the dynamics of an injector, by which the fuel mixture is injected in an internal combustion engine, is ascertained; and where the concentration of alcohol is determined in light of a course of the characteristic curve. The invention also relates to a method for operating an internal combustion engine and a system for determining a concentration of alcohol in a fuel mixture. | ||
