    摘要: An ignition device for an internal combustion engine is provided which improves ignition while reducing electric power consumption. An ignition device for an internal combustion engine includes an ignition plug that is placed with a tip exposed on an end in an axial direction of a combustion chamber formed in a cylinder and that includes a central electrode and a grounding electrode provided opposing each other at the tip, and a magnetic field former that forms a magnetic field in a direction in which a magnetic field vector substantially vertically passes through an approximate two-dimensional plane including a spark discharge path formed, by a gas flow ejected to the end in the axial direction of the combustion chamber, between the central electrode and the grounding electrode, and extending in an approximate U shape in a direction orthogonal to the opposing direction of the electrodes.

    摘要: A controller for a free piston generator that is capable of more accurately controlling the behavior of a piston than conventional controllers is provided. During power generation of a free piston generator 10, a controller 18 controls the amount of power generation to cause the velocity of a piston 14 to reach a first velocity command value (for an expansion stroke) and a second velocity command value (for a compression stroke) by electric braking. During motoring, the controller 18 controls the amount of power supply to cause the velocity of the piston 14 to reach the first and second velocity command values. The controller 18 sets the first and second velocity command values by setting first and second velocity command values for a certain round-trip period based on a top dead center position and a bottom dead center position of the piston 14 for the previous round-trip period.
