Abstract
An engine system comprises a fuel tank, an internal combustion engine, a generator, a recoil starter, a control unit, an injector, a fuel pump, an ignition apparatus, and a detection unit that detects a number-of-rotations of the internal combustion engine. The control unit, in a starting period of the internal combustion engine using the recoil starter, determines whether or not the internal combustion engine can perform self-sustaining rotation based on the number-of-rotations, and if the internal combustion engine cannot perform self-sustaining rotation. Electric power is not supplied to the ignition apparatus, the injector, and the fuel pump when the internal combustion engine cannot perform self-sustaining rotation. The electric power is supplied to them when the internal combustion engine can perform self-sustaining rotation.
