Abstract
An engine system includes: a mixture portion capable of mixing a first liquid as a main fuel with a second liquid at a predetermined mixture ratio; an engine to which a mixed fuel produced by mixing the first liquid with the second liquid is fed from the mixture portion; and a control portion controlling the mixture ratio of the mixed fuel to be a target mixture ratio based on a driving state of the engine. The control portion controls the target mixture ratio based on a feeding period from the time when the mixed fuel is fed from the mixture portion to the time when the mixed fuel arrives at the engine.
