摘要： PURPOSE: To facilitate work regulating a frequency and enable the frequency, after it is set, to ensure the stability, by providing a frequency setter circuit which changes the set frequency of an AC generator by the level change of a frequency setting voltage signal given to a control circuit.
CONSTITUTION: When a frequency selector switch 27 is placed in an off-condition, high voltage is supplied to a control circuit 26 by voltage input from an input terminal 21, and the circuit 26, deciding a set frequency to be set to 50Hz and calculating the set frequency as 50Hz, outputs a control value corresponding to a driver circuit 38. While if the frequency selector switch 27 is switched to be turned on, the circuit 26, to which low voltage is supplied because the voltage from the input terminal 21 is relieved through the frequency selector switch 27, decides the set frequency to be set to 60Hz and calculated as 60Hz, outputting a control value corresponding to the driver circuit 38. In this way, an engine 41 controls a generator 31 generating an assigned set frequency.

摘要： PURPOSE:To reduce the revolution-vibration on a plane perpendicular to a crankshaft by reducing the moment around the crankshaft which is generated by a 1-shaft primary balancer by setting the cylinder center line in eccentricity towards the primary balancer side. CONSTITUTION:A 1-shaft primary balancer 20 is arranged in parallel to a crankshaft 12, and interlocking-connected to the crankshaft 12 by a pair of gears and revolved in the feeding direction at the equal speed to the crankshaft 12. Further, the cylinder center line C0 is in eccentricity by the eccentricity amount E towards the 1-shaft primary balancer 20 with respect to the center O1 of revolution of the crankshaft 12. Therefore, the moment 1 in the feeding direction around the crankshaft which is generated by the reciprocating inertial force of a piston 10 in eccentricity operates to offset the moment around the crankshaft 12 which is generated by the 1-shaft primary balancer 20.

摘要： PURPOSE:To remove dust contained in cooling air efficiently, by constructing an engine chamber in a double-shell structure, and forming a cooling-air inlet opening having a large opening area and provided with a screen in the outer shell while forming a section for turning the flow of cooling air in the inner shell. CONSTITUTION:When an engine 5 is started, cooling air is drawn into the space formed between an outer shell 1 and an inner shell 2 of an engine room 4 through a screen formed in the outer shell 1. Large particles of dust contained in the cooling air are captured by the screen. Since the cooling-air inlet opening having the screen is formed to have a large opening area and the speed of cooling air passed through the screen is low, the amount of dust particles of small masses passed through the screen is reduced. Further, while the cooling air is passed to a flow reversing section 3, dust particles having large masses are dropped into a dust collecting pocket 9 but dust particles that are not reversed completely at the reversing section and brought into collision against a side wall 8a are dropped into a dust collecting pocket 8. Further, since the speed of cooling-air flow in the engine chamber 4 is low, dust contained in the cooling air is dropped to the bottom 4a of the engine room 4 while passing through the engine room 4. Thus, dust contained in the cooling air is removed completely.

摘要： PURPOSE:To promote the atomization of fuel upon low and middle speeds of the engine and improve the igniting property of the engine by a method wherein a communicating part, being opened near the upper dead point of a piston and communicating the crank chamber with an exhaust port, is provided to flow a part of exhaust gas into the crank chamber. CONSTITUTION:The piston 3 is positioned near the upper dead point, the compression of the mixture in a combustion chamber 1a is finished, the engine is in a condition immediately before explosion due to the ignition of an ignition plug 12 and, on the other hand, the mixture is being flowed into the crank chamber 11 through a suction port 9. The crank chamber 11 is communicated with the exhaust port 8 through the communicating port 14 and a part of the exhaust gas A near the exhaust port 8 flows into the crank chamber 11 of vacuum or normal pressure through the communicating port 14 to heat the mixture in the crank chamber 11. Soon after the piston 3 begins to descend, the communicating port of the piston 3 is closed by a cylinder 2. Thus, the mixture in the crank chamber 11 is heated by the mixture A, enters into the upper cylinder 2 and is compressed thereby completing one cycle.

摘要： PURPOSE:To facilitate the starting of an engine by operating a diaphragm value by a pump pressure at a fixed number of revolutions of an engine for controlling a cylinder pressure. CONSTITUTION:Over a fixed number of revolutions of an engine, a water pump 22 is rotated at a high speed, and a high pressure is introduced into a pressure chamber 20 through a pipe 21 to push a diaphragm 16. Consequently, a valve 2 is seated on a valve seat 11 against the elasticity of a spring 15 and the compressed gas in a combustion chamber 6, and a decompression hole 3 is closed. During the stoppage of the engine, or under a fixed number of revolutions, the pressure in the pressure chamber 20 is low, and the valve 2 is separated from the valve seat 11 by the elasticity of the spring 15 to open the decompression hole 3. While the decompression hole 3 is kept opened, a part of gas during the rise of a piston is leaked to an exhaust port 5 through a decompression hole 3 to lower the pressure of the compressed gas, and the engine can be started by a small torque. This construction permits to start engine easily, and stabilize the driving state during idling.

摘要： PURPOSE:To form a device in a small size and promote its cost down, by changing a pulse duration time of a throttle control signal, which an arithmetic circuit outputs to an intake air quantity control valve driving circuit, and actuating a control valve driving mechanism so as to control a speed to a predetermined value. CONSTITUTION:A control device, in which a control value from a comparator arithmetic circuit 26 on the basis of a voltage signal generated in an AC generator 20 is output to a driver circuit 28 as a pulse train, changes a duration time of each pulse corresponding to the arithmetic result of a throttle opening compensation quantity. In this way, a throttle opening is changed because mean voltage Va output to the circuit 28 changes. Next, the circuit 28 converts a signal from the circuit 26 into a signal suitable for driving a rotary solenoid 56. And the control device, driving the solenoid 56 by a voltage signal from the circuit 28 and integrally turning also a valve main unit 54 because a rotary shaft 55 turns corresponding to a level of voltage, opens and closes a throttle valve 31. In this way, the control device, holding the speed of an engine 32 to a predetermined value so as to obtain a predetermined output from the AC generator 20, can be formed in a small size by eliminating the necessity for a D/A converter.
