Abstract
The present invention provides a batteryless engine system comprising a first detection unit configured to detect a rotation speed of an internal combustion engine, a second detection unit configured to detect a voltage of a capacitor in which charges are accumulated, and a control unit operated by a power supplied from a generator and configured to control supply of a power from the generator to an injector, a fuel pump, and an ignition device based on the rotation speed detected by the first detection unit and the voltage detected by the second detection unit in a starting period of the internal combustion engine by a recoil starter.
Claims6
A batteryless engine system comprising:
- an internal combustion engine;
- a fuel tank configured to store fuel of the internal combustion engine;
- a generator configured to be driven by the internal combustion engine and generate power;
- a recoil starter configured to start the internal combustion engine;
- a capacitor configured to accumulate charges generated by the power generation;
- a first detection unit configured to detect a rotation speed of the internal combustion engine;
- a second detection unit configured to detect a voltage of the capacitor in which the charges are accumulated;
- an injector operated by the power supplied from the generator and configured to supply the fuel to the internal combustion engine;
- a fuel pump operated by the power supplied from the generator and configured to supply the fuel stored in the fuel tank to the injector;
- an ignition device operated by the power supplied from the generator and configured to ignite the fuel compressed by the internal combustion engine;
- and
- a control unit operated by the power supplied from the generator and configured to control supply of the power from the generator to the injector, the fuel pump, and the ignition device based on the rotation speed detected by the first detection unit and the voltage detected by the second detection unit in a starting period of the internal combustion engine by the recoil starter.
