PURPOSE:To provide a fuel supply device in which fluid passage loss is small delay of responsiveness is small, and influence of bubble is small, regardless of its small size. CONSTITUTION:An alcohol sensor is set inside a fuel sump part 36 which is the main part of a pressure regulator 1 in a fuel distribution pipe, or inside a bypass flow passage 25 integrated with a pressure regulator 1 and connecting the high pressure part 11 of the pressure regulator to the high pressure part 12 thereof. An alcohol mixture rate is detected by an alcohol sensor time serially and a means which estimates the alcohol mixture rate inside the fuel injection device based thereon is provided. Consequently, it is possible to provide a fuel supply device in which a fluid passage loss is small, delay of responsiveness is small, and influence of bubble is small regardless of its small size. |
