    摘要: In a dual-fuel internal combustion engine which can selectively use gaseous fuel such as CNG or liquid fuel such as gasoline, a pair of intake passages are independently connected to a combustion chamber of the engine, and a gaseous fuel supply device and a liquid fuel supply device are provided in the corresponding intake passages so that the liquid and gaseous fuels may not mix with each other when the fuel for the engine is switched over one from the other as they are introduced into the combustion chamber through different intake passages. Further, by switching the operating mode of the intake valve when changing the fuel, the configuration of the intake passage can be optimized for each fuel, and the timing and the lift of the intake valves may also be optimized for each fuel without complicating the control structure of the overall system. The present invention can improve the torque output and the emission property of the dual-fuel engine.

    摘要: A ring-shaped metal gasket 10 in which a metallic ring 10b is fitted to at least one of two valley portions 11b, 12b in the ring-shaped metal gasket 10a. The metal gasket 10 is free of plastic deformation even if a large compressive load is applied thereto and difficult to undergo fatigue destruction. Even if a difference in pressure between a fluid side to be sealed and a non-fluid side on the opposite side is high, the gasket is hard to damage.

    摘要: A valve operating system in an internal combustion engine includes a cam shaft provided with a plurality of valve operating cams, a plurality of rocker arms positioned adjacent one another, an associative operation switch capable of being switched between a state in which it permits the rocker arms adjacent each other to be operated associatively with each other, and a state in which it releases the associative operation. An urging means for urging the free rocker arm of the plurality of rocker arms toward the valve operating cam corresponding to the free rocker arm, which becomes free relative to an engine valve, when the associative operation switch is brought into the associative operation releasing state. The free rocker arm is provided with first and second support walls spaced apart and opposed to each other, and a roller is provided in rolling contact with a valve operating cam corresponding to the free rocker arm, and is rollably supported on a support shaft mounted to extend between the support walls through a bearing. In such valve operating system, one of the support walls included in the free rocker arm is integrally provided with a receiving portion which contacts with the urging means. Therefore, the structure of the free rocker arm can be simplified in such a manner that the receiving portion is positioned to the side of the roller. In addition, an increase in size of the free rocker arm can be avoided, and the inertial weight is reduced. Thus, it is possible to conveniently accommodate the high-speed rotation of the internal combustion engine.

    摘要: A drive cam follower operatively connected to an engine valve and a free cam follower capable of becoming free relative to the engine valve are adjacently disposed and adapted to impart in mutually different modes of operation in response to said engine valve rotation of a cam shaft. A connection change-over mechanism is provided between the cam followers and is capable of changing-over the interconnection and disconnection thereof, and resilient biasing means is provided between the free cam follower and the engine body for resiliently urging the free cam follower toward the cam shaft. The resilient biasing means comprises an urging piston slidably received in the engine body for abutment against the free cam follower, and a spring arrangement interposed between the urging piston and the engine body to resiliently bias the urging piston in a direction to abut against the free cam follower. The spring arrangement may comprise series-related springs having different spring constant with one of the springs having a non-linear load characteristic. A vent opening and a lubrication arrangement are provided to facilitate operation of the piston. The urging piston is provided, at its end closer to the free cam follower, with an abutment formed with a smaller diameter to abut against the free cam follower. This facilitates assembly of the resilient biasing means to the engine body, and makes it possible to dispose the resilient biasing means in proximity to a pivoting point of the free cam follower.

    摘要: A pentose such as ribose, arabinose, 2-deoxyribose, 1-methoxy-2-deoxyribose or the like is reacted with a phosphoric acid donor such as a pyrophosphoric acid or an alkali metal salt thereof in the presence of an acid phosphatase. Thus, a pentose-5-phosphate ester can be produced, such as a ribose-5-phosphate ester, an arabinose-5-phosphate ester, a 2-deoxyribose-5-phosphate ester, a 1-methoxy-2-deoxyribose-5-phosphate ester or the like.
