  • Patent number: 10533518
    Abstract: An internal combustion engine having an independent combustion chamber comprises a combustion chamber (1), an air inlet system (2), a material feeding system (3), and a working system (4). The air inlet system (2) and the combustion chamber (1) are connected together and configured to transport a compressed air to the combustion chamber (1). The material feeding system (3) and the combustion chamber (1) are connected together and configured to transport a fuel to the combustion chamber (1). The combustion chamber (1) has a fixed volume and has no movable wall such as a piston. The fuel continues to be burned in the combustion chamber (1) to generate a high-temperature and high-pressure gas, and chemical energy of the fuel is converted into internal energy of the high-temperature and high-pressure gas. The working system (4) and the combustion chamber (1) are connected together. The piston (21) of the working system (4) works to convert the internal energy of the gas into a mechanical energy.

  • Patent number: 10533528
    Abstract: A starter is installed in a vehicle. In the starter, a crank shaft is driven by a motor which rotates a pinion gear in a state where a ring gear connected to the crank shaft is in engagement with the pinion gear. Thus, an engine is started. The starter sets a start-up period depending on the type of the start-up trigger that generates a start-up request for the engine, and sets a current supplied to the motor on the basis of the set start-up period. Thus, at least either of a rotation speed and an output torque of the motor is controlled. This control is implemented by a control circuit.
