Abstract: The size of the plasma produced by a plasma-generating device that generates plasma using electromagnetic (EM) radiation is enlarged. The plasma-generating device has an EM-wave-generating device that generates EM radiation, a radiation antenna that emits the EM radiation supplied from the EM-wave-generating device to a target space, and a receiving antenna located near the radiation antenna. The receiving antenna is grounded such that an adjacent portion that is close to the radiation antenna has a higher voltage while the EM radiation is emitted from the radiation antenna. The plasma-generating device generates plasma in the target space near the radiation antenna and the adjacent portion by emitting EM radiation from the radiation antenna.

Abstract: A fuel property determination apparatus for an internal combustion engine is applied to an internal combustion engine that is equipped with an ignition plug and an ignition timing controller. An electronic control unit provided in the fuel property determination apparatus executes a determination process of making a determination on a property of a fuel supplied to the internal combustion engine based on an ignition sufficiency ratio, during a predetermined period after startup of the internal combustion engine. The electronic control unit is configured to determine that the property of the fuel is heavy when a determination index value that is obtained by subjecting the ignition sufficiency ratio to a smoothing process is equal to or larger than a predetermined threshold. The electronic control unit is configured to set a smoothing coefficient to a value corresponding to each of a first period, a second period, and a third period.
