摘要： PROBLEM TO BE SOLVED: To provide an intake air heater not increasing its weight accompanied by an increase in the number of part items, providing improved energy efficiency, and heating intake air even in starting at a low temperature. SOLUTION: A radiating part 50 composed of a radiator 14 and a condenser 42 is arranged at the end of a second passage 32 formed by an intake pipe 21. The condenser 42 of the radiating part 50 generats heat before an engine body 11 is started by a heat pump 40 operated independently from the engine body 11. Therefore, even if a temperature of outside air is low in starting the engine body 11, air sucked into the engine body 11 is heated. Air heated by the radiating part 50 is supplied to the engine body 11 also in a low load state. As a result, the density of air introduced into the engine body 11 is lowered, and fuel consumption is reduced. Meanwhile in a high load state, low-temperature outside air is supplied from a first passage 31 to the engine body 11. Therefore, the output of the engine body 11 is improved.

摘要翻译：要解决的问题：为了提供不增加其重量的进气加热器，伴随着零件的数量的增加，提供改进的能量效率，以及即使在低温启动时也能加热进气。解决方案：在由进气管21形成的第二通道32的端部处设置由散热器14和冷凝器42组成的散热部分50.散热部件50的冷凝器42在发动机主体11之前产生热量由独立于发动机主体11的热泵40启动。因此，即使在启动发动机主体11时外部空气的温度低，吸入发动机主体11的空气也被加热。由辐射部50加热的空气也以低负载状态供给到发动机主体11。结果，引入发动机主体11的空气的密度降低，燃料消耗降低。同时在高负载状态下，从第一通道31向发动机主体11供给低温外部空气。因此，能够提高发动机主体11的输出。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To reduce intake noise in a wide frequency band by utilizing sound waves generated on either one of vibration plates and sound waves generated on the other of them.
SOLUTION: This noise controller is provided with the vibration plates 11 for partitioning a silencer 15 into a main sound pressure generating chamber 13 and a back cavity 14 to suppress intake noise by the "synthetic waves" synthesized by main sound waves given into an intake pipe 2 from the main sound pressure generating chamber 13 and sub-sound waves given into the intake pipe 2 from the back cavity 14 by passing through a back cavity discharge passage 19. Since the sound waves generated in not only the main sound pressure generating chamber 13 but also the back cavity 14 are utilized in this way, quantity of energy to be consumed is suppressed. Since "primary frequency of explosion" and "frequency being multiple of the primary frequency of explosion" appear in the "synthetic wave" in the same way as in intake noise, the intake noise can be reduced in a wide frequency band.

摘要翻译：要解决的问题：通过利用在振动板中产生的声波和在另一个振动板上产生的声波来减小宽频带中的进气噪声。解决方案：该噪声控制器设置有振动板11，用于将消声器15分隔成主声压发生室13和后腔14，以通过由主声波合成的“合成波”来抑制进气噪声来自主声压产生室13的进气管2和通过后腔排放通道19从后腔14供给到进气管2中的副声波。由于不仅在主声压下产生的声波以这种方式利用发电室13而且后腔14，抑制了消耗的能量。由于与“进气噪音”相同，因为“合成波”中出现“主要爆炸频率”和“频率是爆炸主频倍数”，因此可以在宽频带内降低进气噪声。版权所有（C）2007，JPO＆INPIT

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 prevent unburnt HC resulting from the adhesion of fuel to the wall surfaces of cylinders or the like from emanating into the atmosphere during cold start.
SOLUTION: Fuel supply is effected by a main injector 31 which injects fuel collected in a fuel tank 4 and a sub-injector 32 which injects the vaporized fuel in the fuel tank 4. The vaporized fuel is continually and stably generated by generating air bubbles using an air bubble generating means 56 immersed in the fuel collected in the fuel tank 4. During a warming process or the like, the fuel supply by the sub-injector 32 which supplies the vaporized fuel containing large amounts of low-boiling-point components is selected to control the adhesion of the fuel.

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.
