摘要： A device for evaluating catalyst performance deterioration includes an air-fuel ratio sensor and a temperature sensor. The degree of catalyst performance deterioration per unit time is calculated based on the concentration of oxygen in the exhaust gas and the temperature of the catalyst. The deterioration of the catalyst is evaluated on the basis of the accumulated value of the degree of catalyst performance deterioration per unit time.

摘要： An internal combustion engine in which a three-way catalyst (12) for purification of the exhaust gas is arranged in the exhaust passage, wherein the relationship between the magnitude of the stress causing deterioration of the three-way catalyst (12), for example the catalytic bed temperature, and the rate of deterioration of the performance of the catalyst is found. A durability test is performed by raising the catalytic bed temperature higher than that of the vehicle under market driving. The length of the durability test at this time is determined from the relationship between the catalytic bed temperature and the rate of deterioration of the performance of the catalyst so as to give the same degree of deterioration of the performance of the catalyst as with market driving. The length of the durability test required for giving the same degree of deterioration of the performance of the catalyst is much shorter than the market driving time.

摘要： In a vehicle driveability evaluation system, an engine is coupled to a dynamic dynamometer which is capable of changing a load torque and a speed in a very short time. A control unit controls the dynamic dynamometer so that the load torque and the speed of the dynamometer simulate the load and the speed of the engine when it is mounted on an actual vehicle. The driveability evaluation test is performed by operating the engine while simulating various running conditions of the vehicle by the dynamic dynamometer. Engine operating parameters such as an engine speed and an output torque are converted by a driveability data generating unit into driveability data such as an acceleration and vibration of the vehicle in accordance with the characteristic of the vehicle. These driveability data are converted by a sense-data generating unit into stimuli such as visual images, sounds and forces which can be directly perceived by the human senses. Therefore, an inspector can directly perceive the driveability of the actual vehicle from the stimuli generated by the sense-data generating unit without actually mounting the engine in the vehicle body.

摘要： An electrically heated catalytic converter having a substrate for a catalyst which is formed as a scroll-like cylindrical laminated assembly, a rod like metal center electrode connected to the laminated assembly, and a casing accommodating the laminated assembly which also acts as an outer electrode. The center electrode extends from the laminated assembly along the central axis, bends towards the wall of the casing and penetrates the casing. The center electrode is fixed to the casing via an insulating material at the point where it penetrates the casing. Four buffer members are interposed between the laminated assembly and the casing, each of buffer members being made of a metal plate, one end of the respective buffer members being fixed to the casing at the portion near the penetration point of the center electrode, the other end of the respective buffer members being fixed to the outside of the laminated assembly. During the operation of the engine, the laminated assembly is displaced by the thermal expansion of the center electrode. In the present invention, thermal expansions also occurs in each of the buffer members. Since the ends of the buffer members are fixed near to the penetration point at which the center electrode is fixed to the casing, the amounts of the displacements of the other ends of the buffer members where the buffer members are fixed to the laminated assembly are equal to the displacement of the laminated assembly caused by the thermal expansion of the center electrode. Therefore, the displacement of the laminated assembly is not hindered by the buffer members. Thus, the buffer members support the laminated assembly without causing excessive stress in the laminated assembly.
摘要翻译：一种电加热催化转化器，其具有形成为涡卷状圆柱形层压组件的催化剂用基板，与层压组件连接的棒状金属中心电极，以及容纳层叠组件的壳体，其还用作外部电极。中心电极从夹层组件沿着中心轴线延伸，朝向壳体的壁弯曲并穿透壳体。中心电极在穿透壳体的位置经由绝缘材料固定到壳体。四个缓冲构件插入在层压组件和壳体之间，每个缓冲构件由金属板制成，各个缓冲构件的一端在靠近中心电极的穿透点的部分固定到壳体，另一个各个缓冲构件的端部固定到层叠组件的外侧。在发动机操作期间，层叠组件通过中心电极的热膨胀而移位。在本发明中，在每个缓冲部件中也发生热膨胀。由于缓冲构件的端部固定在靠近中心电极被固定到壳体的穿透点附近，所以缓冲构件的固定到层叠组件的缓冲构件的另一端的位移量相等涉及由中心电极的热膨胀引起的层压组件的位移。因此，层压组件的位移不受缓冲构件的阻碍。因此，缓冲构件支撑层叠组件，而不会在层叠组件中引起过大的应力。

摘要： An electrically heating catalytic apparatus that quickly heats catalyst to an activation temperature even when the engine is started at a low temperature below the catalyst activation temperature. The apparatus employs an electrically conductive catalyst carrier that is electrically heated. The carrier is provided with local hot spots to be energized. Since the heat is locally generated, the heat capacity of the catalyst carrier is small to shorten a temperature increasing time.

摘要： A knocking detection method for internal combustion engines in which vibrations of the engine are detected by a vibration sensor and a peak value of the vibrations during a predetermined interval near the top dead center in each revolution of the engine is sampled. The peak value for each revolution is stored for a predetermined number of revolutions of the engine and an average value of the peak values is obtained. Then the ratio of each peak value to the average value is calculated, and the number of ratios whose magnitude exceeds a predetermined magnitude is expressed in terms of a rate or a percentage with respect to the total number of ratios, i.e., the predetermined number of revolutions of the engine. The presence or absence of the knocking is determined whether or not the rate or percentage is above a reference rate or percentage.

摘要： A fuel supply system for engines having a carburetor which has a float chamber and a vapor bleed passage connected to the float chamber, wherein a part of a fuel supply passage means for supplying fuel from a fuel tank to the carburetor traverses through the float chamber so that the fuel flowing through the fuel supply passage means absorbs heat from the fuel contained in the float chamber. The fuel entering into the float chamber releases volatile light components as vapor towards the vapor bleed passage while the liquid fuel contained in the float chamber becomes a more stable liquid due to the release of volatile components and the cooling effected by heat exchange with the fuel flowing through the fuel supply passage means.

摘要： Disclosed is a fuel feed device of an internal combustion engine. The fuel supply conduit communicating the carburetor and the fuel tank is arranged in the carburetor for cooling the carburetor and for vaporizing the low boiling components in the fuel only when the temperature of the engine is higher than a predetermined level. The fuel flowing out from the fuel supply passage located in the carburetor is introduced into a low boiling component separator. In this separator, the low boiling components in the fuel are removed, and then the fuel consisting of the high boiling components is fed into the carburetor to prevent the occurrence of an abnormal fuel metering operation under a high-temperature condition.
