Abstract: In an alcohol concentration estimation apparatus for an engine, a first crank angular speed (?1) within a first predetermined interval overlapping with the compression top dead center is calculated, and a first variation amount (??1) is calculated by subtracting ?1 from an average engine speed.

The alcohol concentration estimation apparatus eliminates requirement of sensors for detecting an intake air mass.
