摘要： PURPOSE:To make sure mobility as a load working car of compact loading and improve appearance of a car body by constructing a balancer weight out of a filling container of a hydrogen occulusion alloy and of a storage container in which a heating medium is provided flowingly. CONSTITUTION:A balancer weight 2 is loaded on the rear part of a car body so as to hold equilibrium of the center of gravity of the car body, and is formed in a shape similar to that of a general balancer weight, its outer surface being a storage container 3 composed of an insulator. In the storage container 3, tubular filling containers 4, 5 filled up with hydrogen occulution alloys that exhaust hydrogen gas based on heat exchange reaction are arranged, and an installation and derivation tubular passages 7, 8 are connected on the upper and lower parts, whereby a heating medium installed from the installation tubular passage 7 is flown in condition that the storage container 3 is filled up, and is derived from the derivation tubular passage 8. There are provided tubular passages 4a, 5a through which derived hydrogen gas is exhausted from the hydrogen occulution alloys in the filling containers 4, 5, and which are connected with a hydrogen engine through a main tubular passage 6, so as to supply hydrogen gas.

摘要： PURPOSE:To prevent occurrence of hunting in a two barrel carburettor of a gasoline engine equipped with an air governor to be caused by interference of the primary valve and secondary valve in a high load operating condition such that the two valves are fully opened. CONSTITUTION:A sensor 45 senses the degree of opening of a primary throttle valve, while a valve opening upper limit switch 53 for the secondary throttle valve senses that the secondary throttle valve has opened to the upper limit in throttle limitation, and a secondary throttle valve closing direction stopper 47 restricts the operation of the secondary valve in the direction of closing. In the high load operating condition, the secondary valve will not be closed even though a governor valve situated below is actuated, bent is held fully opened so that no hunting swill occur because of interference of the secondary valve with the governor valve.

摘要： PURPOSE:To improve controllability by a small amount of software by finding a PID gain value while utilizing the derived function of a reverse function of the characteristic equation of an engine, correcting the value, and enabling PID control of the characteristics of the engine under other all respective conditions. CONSTITUTION:The opening of an accelerator 2 is detected by a sensor 3, and an ECU 4 sets a target engine speed which corresponds to the accelerator opening. An actual engine speed is then detected by an electromagnetic pickup 7 to be inputted to the ECU 4, and the ECU 4 calculates deviation of the target engine speed from the actual engine speed to correct a constant gain value by the drived function of a reverse function of the characteristic equation of an engine. The PID calculation is performed by the corrected value to determine the amount of movement of a throttle valve 13. Then the ECU 4 commands a step motor 12 to operate to move the throttle valve 13. Thus, the actual engine speed is rotation-controlled so that it reaches the target engine speed.

摘要： PURPOSE:To enhance the workalility of installation and change in the swirl ratio over a wider range by furnishing a partition plate in a suction port, partitioning into No.1 and No.2 suction passage on the regular and reverse swirl stream sides, and installing a control valve to control the proportion of suction gas amounts in the two passages. CONSTITUTION:When a control valve 21 is fully open while another 22 is full closed, most of the suction air from an intake manifold 94 and No.1 suction passage 11 is turned into regular swirling stream S1 with starting of the internal combustion engine concerned, and upon descending in a done 91, flows into a combustion chamber 95. Therefore, the swirl ratio in the combustion chamber 95 becomes maximum. If in this condition, the valve 22 is opened slowly, air flows into the dome 91 even from No.2 suction passage 12, and reverse swirling stream S2 enlarges gradually. Therefore, the swirl stream S1 is offset with S2 and weakens gradually, and the swirl ratio sinks. When the valve 21 is closed slowly after the valve 22 is full opened, the S1 is further weakened by S2 to cause the swirl ratio to nullify at last.

摘要： PURPOSE:To prevent the generation of backfire by forming a hydrogen discharge port having an opening/closing valve, on an intake manifold, and by opening- controlling said opening/closing valve when an engine stops and discharging the hydrogen staying in the intake manifold outside. CONSTITUTION:In a hydrogen storage alloy tank 1, the hydrogen gas generated by heating a hydrogen storage alloy by the engine cooling water, etc. The generated hydrogen gas is supplied into a caburetor 6 through a filter 2. reducing valve 4, and a regulator 5, and mixed with the air supplied from an air cleaner 7, and the mixed gas is supplied into a hydrogen engine 9 through an intake manifold 8. In this case, a hydrogen discharge port 10 is formed in the upper part of the intake manifold 8, and an opening/closing valve 11 is installed at the discharge port 10. When, in a drive controller 12, the engine stop is detected from the output of a revolution detecting sensor 14, the opening/ closing valve 11 is opened to discharge the mixed gas in the intake manifold 8 outside.

摘要： PURPOSE:To perform swirl control at the time of low temperature start-up simply at a low cost by partitioning an intake port into plural intake ports for generating normal and reverse swirl flows, and opening the intake port for generating the reverse swirl flow at the low temperature start-up time of an engine. CONSTITUTION:An intake port 1 is partitioned into a first and a second intake ports 11, 12 by a partition plate 10, thus generating respectively normal and reverse swirl flows S1, S2 in a combustion chamber. A control valve 2 is disposed at the entrance of the second port 12. This control valve 2 is energized in the closing direction by a return spring 3 and moved in the opening direction by a wire 4. The wire 4 is connected to the lever 73 of a low temperature start-up time spark advance device 7 in an injection pump 6. At the low temperature start-up time of an engine, the lever 73 is operated by the piston 72 of the device 7 so as to open a control valve 2 against the return spring 3 through the wire 4. The swirl ratio can be thereby minimized, and startability is improved.

摘要： PURPOSE:To restrict excessive deformation of teeth by providing tooth- reinforcement core wires swelled continuously with a belt body-reinforcement core wire. CONSTITUTION:A belt body 1 made of chloroprene rubber is reinforced by an endless circular belt body-reinforcement core wire 2 which is formed with a plurality of tooth reinforcement core wires 4 swelled continuously with the belt body-reinforcement core wire 2 for respective rubber teeth 3 integrally formed with the belt body 1 so as to reinforce the teeth 3. The outer surface of the belt body-reinforcement core wire 2 and outer and inner surfaces of the tooth-reinforcement core wires 4 are covered with rubber to mold a belt body 1 with a plurality of teeth 3 formed integrally therewith on one side thereof. Thus constructed, even when an external force is exerted on the teeth 3, deformation of the teeth 3 can be restricted, permitting reduction of their wear.
