摘要：
An engine system for determining an alcohol concentration in fuel is disclosed. In one example, engine throttle position, fuel pulse width, and air-fuel ratio form a basis for determining alcohol concentration of a fuel combusted in an engine. The system and its related method may improve engine operation in conjunction with detecting an alcohol concentration of a fuel.
