摘要： PROBLEM TO BE SOLVED: To provide a suction device generating vibration of reverse phase at high accuracy so as to be fitted to pressure fluctuation of sucked air in the suction system, reducing noise and enhancing output of an engine.
SOLUTION: A vibration plate 13 is vibrated by compression air delivered from a compression pump 11. Compression air of reverse phase relative to pressure fluctuation of sucked air is delivered from the compression pump 11 by a compression air control part 30 in synchronous to the engine. Therefore, phase and amplitude of the pressure fluctuation generated by the vibration of the vibration plate 13 is controlled at high accuracy fitted to rotation of the engine. Thereby, the pressure fluctuation of sucked air flowing in a suction passage 27 is denied by the vibration of reverse phase generated by the vibration plate 13. As a result, noise of the sucked air is reduced, the pressure of sucked air becomes constant and volume efficiency of the sucked air sucked to the engine is enhanced.

摘要： PROBLEM TO BE SOLVED: To provide a fuel storing device and a method for suppressing fuel evaporation inside the fuel storing device capable of efficiently suppressing the generating amount of evaporated fuel.
SOLUTION: A heat storage means 5 is provided having a heat storage material 52 enclosed therein for heat-exchanging with a stored fuel F of a tank 11. A characteristic of saturated vapor pressure is that rate of change of the saturated vapor pressure in regard to temperature change is large on the high temperature side of the stored fuel F, and the rate of change of the saturated vapor pressure is small in regard to temperature change on the low temperature side. Therefore, between an action of the heat storing material 52 suppressing a temperature rise of fuel and suppressing a rise in the saturated vapor pressure in regard to the temperature rise of the stored fuel F, and an action of the heat storing material 52 suppressing temperature drop of fuel and drop of the saturated vapor pressure in regard to the temperature drop of the stored fuel F, the former is larger. As a whole, fuel evaporation is suppressed.

摘要： PROBLEM TO BE SOLVED: To carry out a good fuel vapor treatment with a simple constitution without using a HC concentration sensor for monitoring a concentration of a purge fuel vapor (purge gas) in heater heating thermostat control. SOLUTION: When the fuel vapor released from a fuel tank 20 and adsorbed and retained on a fuel adsorption layer 35 (35a, 35b) in a canister 30 is purge- controlled by ON/OFF control of a purge valve 23, a heater plate built in the canister 30 is ON/OFF controlled based on a concentration of the purge fuel vapor presumed and calculated accompanying with an air/fuel ratio control of the internal combustion engine. Thereby, a sensor for detecting the concentration of the purge fuel vapor fed out to an intake passage 2 of the internal combustion engine from the canister 30 through purge passages 22, 24 is not required, and thus allowing a good fuel vapor treatment with a simple constitution.

摘要： PROBLEM TO BE SOLVED: To clarify the relationship between a heating value of a heater and the shape of a fuel adsorbing layer 4 to obtain the temperature regulating effect over the whole area of the fuel adsorbing layer 4. SOLUTION: The fuel adsorbing layer 4 formed inside of a canister is defined into an upper adsorbing layer 4A and a lower adsorbing layer 4b by a partitioning plate 13 in which a heater is buried. The relationship between the heating value of the heater and a thickness X of the upper adsorbing layer 4A and the lower adsorbing layer 4B is determined to satisfy that a temperature of a part nearest to a heating face of the heater, of the fuel adsorbing layer 4 is lower than an ignition point of the fuel, and a temperature of a part farthermost from the heating face of the heater is higher than a boiling point of the fuel. Whereby the desorbing performance of activated carbon C can be improved by heating the fuel adsorbing layer 4 by the heater in desorption, and the approximately full amount of the adsorbed fuel vapor can be desorbed. As a result, as the fuel vapor does not remain in the canister, the fuel vapor flowing in adsorption can be surely and completely adsorbed.

摘要： PROBLEM TO BE SOLVED: To prevent generation of measuring error caused by mixing moisture and fuel with lubricating oil, in a device for detecting insoluble matter in lubricating oil. SOLUTION: A temperature of lubricating oil detected by a thermometer 5 and an information of an operating time of an internal combustion engine measured by a timer 7 are inputted in an ECU 6, and detection interrupting signal is outputted in the case where the temperature of lubricating oil not exceed 100 deg.C for 5 minutes or more continuously for 10 hours or more. On the other hand, in the case where the temperature exceeds 100 deg.C for 5 minutes continuously, it is considered as that all moisture are evaporated, and thereby, a detecting operation is resumed. In the sum of operating times measured by the timer 7, for example, in the case where the operating time exceeds 100 hours by light oil, a correction necessary signal is outputted, and thereby, reduction of measuring accuracy caused by mixing fuel with lubricating oil is prevented.

摘要： PROBLEM TO BE SOLVED: To prevent deterioration of the measurement precision due to adhesion of particles to a prism and glass surface of an optical sensor in an apparatus for measuring the concentration of particles of insoluble components in a lubricating oil. SOLUTION: A lubricating oil of which the concentration of insoluble component particles is to be measured is introduced into a measurement chamber 14 from an oil line of an internal combustion engine through a flow route 2. A sensor 15 is installed in the measurement chamber 14 and the concentration of particles of insoluble components is measured by utilizing light absorption, reflection, transmitting or the like. Since ions produced by ionization by an additive in the lubricating oil adhere to the particles and the particles bear electric charge, the particles are vibrated and prevented from adhering to glass face of the sensor by applying AC voltage or current to the lubricating oil from an AC power source 4.

摘要： PROBLEM TO BE SOLVED: To provide a deterioration detector of oil capable of being made compact by making the physical size of a float small.
SOLUTION: The light emitting part 23 and light detecting part 24 of the detector body 21 fixed to the other end of the stay extending from one side end of an oil pan to the other side thereof are arranged in mutually opposed relationship so as to hold the oil introducing member 222 downward suspended from the undersurface of the float 22 moved in an up and down direction with respect to the detector body 21 by floating. The quantity of the light emitted from the light emitting part 23 to penetrate through the oil in the oil introducing member 222 is measured by the light detecting part 24 and the properties of the oil is determined on the basis of the quantity of the transmitted light by a determining part. Further, when the height of the oil surface X of the oil lowers, the light path from the light emitting part 23 is cut off in a light shielding part 222b by the float 22 moved downward by accompanying the lowering of the oil surface X and the quantity of the cut-off light is measured by the light detecting part 24 while the oil surface level of the oil is determined on the basis of the quantity of the cut-off light by the determining part.

摘要： PROBLEM TO BE SOLVED: To provide a fuel property detection apparatus capable of accurately detecting the concentration of a biofuel in a mixed fuel of a hydrocarbon fuel and the biofuel despite a compact and a simple constitution and excellent in durability and reliability.
SOLUTION: A fuel property sensor 22 includes a light-emitting element 28 and a light-receiving element 32 for detecting the light transmittance of a fuel in a fuel passage 26 and a light-emitting element 36 and a position detection element 38 for detecting the refractive index of the fuel. Since the light transmittance is related to the RME concentration of the fuel, it is possible to compute its RME concentration on the basis of a detected light transmittance. Since the reflective index is related to the cetane number of the fuel, it is possible to compute its cetane number on the basis of a detected refractive index. The light transmittance is detected through the use of light of the wavelength region between 640 nm and 680 nm.
