Abstract:
To provide a control device for an internal combustion engine that can optimally control a plasma ignition operation independent of fuel type. In a control device 30 of an internal combustion engine 20, which controls plasma ignition operation for causing volume ignition of air fuel mixture by plasma in a combustion chamber 10, a fuel type detection part 40 detects a type of fuel to be supplied to the combustion chamber 10. According to the detected fuel type, a state of plasma or a state of air fuel mixture in the combustion chamber 10 is controlled.
Abstract:
The present invention aims at effectively emitting an electromagnetic wave to a combustion chamber from an emission antenna in an internal combustion engine that promotes combustion of an air fuel mixture utilizing the electromagnetic wave. The present invention is directed to an internal combustion engine including: an internal combustion engine main body formed with a combustion chamber; and an electromagnetic wave emission device that emits an electromagnetic wave to the combustion chamber from an emission antenna. The internal combustion engine promotes combustion of the air fuel mixture by way of the electromagnetic wave emitted to the combustion chamber. The emission antenna is provided in an insulating member and extends along the partitioning surface. The insulating member is provided on a partitioning surface that partitions the combustion chamber. A ground conductor is provided in the insulating member on a side opposite to the combustion chamber in relation to the emission antenna and is electrically grounded.
Abstract:
The object of the present invention is to implement an analysis result provision system that can acquire an analysis result of a target substance without transferring the substance when the substance is analyzed using plasma light information occurred from plasma area where the substance is turned to plasma state. The present invention relates to a provision system of analysis result including an analytical terminal that turns a target substance to plasma state and acquires plasma light information occurred from plasma area, and a host computer. The host computer includes host side communication part that acquires plasma light information via telecommunication line, and information analysis part that analyzes the target substance using plasma light information acquired by the host side communication part. The host side communication part transmits the analysis result of the target substance to the sender of the plasma light information. The analysis result is obtained by the analysis of the information analysis part using plasma light information.
Abstract:
An internal combustion engine has an internal combustion engine body formed with a combustion chamber and an ignition device that ignites an air-fuel mixture in the combustion chamber. Repetitive combustion cycles, including ignition of the air-fuel mixture by the ignition device and combustion of the air-fuel mixture, are executed. The internal combustion engine further has an electromagnetic (EM) wave-emitting device that emits EM radiation to the combustion chamber; a plurality of receiving antennas located on a zoning material that defines the combustion chamber, where the antennas resonate to the EM radiation emitted to the combustion chamber from the EM wave-emitting device; and a switching means that switches the receiving antenna resonating to the EM radiation emitted to the combustion chamber from the EM wave-emitting device among the plurality of receiving antennas.
Abstract:
Provided is a spectroscope that can be manufactured easily, can be reduced in size, and can provide high wavelength resolution of a specific spectral band. Specifically, provided is a spectroscope with a diffraction grating 331 that deflects and separates incident light in different directions depending on to an element of the incident light, at least one optical element 332a, diffusing a light that has passed through this diffraction grating 331 and has entered the optical element 332a, a line sensor 333, which receives the light that has passed through the optical element 332a, thereby only light that has a specific deflection angle within a specific range of wavelengths from among all the light that entered said optical element 332a is selectively expanded and received.
Abstract:
A temperature sensitive body 102 used as a target of an optical temperature measurement, includes an inclusion 202 having an optical property related to an irradiated light varies with a change in temperature, and a light-transmissive outer shell member 200 enclosing the inclusion 202. When a temperature is measured, the inclusion 202 emits light when a light is radiated upon the inclusion 202. Since an optical property related to the irradiated light varies in accordance with a change in temperature, the temperature of the inclusion 202 can be detected by analyzing the outgoing light. A temperature of a location in which the temperature sensitive body is provided can be detected using the temperature of the inclusion 202.
