| PURPOSE:To prevent a carburettor from being affected by heat from an exhaust pipe, by disposing the carburettor in a space surrounded by the front part of an engine, a down tube and a main pipe so that the space is effectively utilized, and as well by leading the exhaust pipe rearward from the rear surface of an engine cylinder. CONSTITUTION:An intake-air pipe 19 for an engine 18 mounted on a frame 1, is connected at its one end the front surface of an engine cylinder 20, and is led at its the other end into a space 30 surrounded by the front part of an engine 18, a main pipe 3 and a down tube 6. In this arrangement, in the above-mentioned space 30 there is disposed a carburettor 21 to which the other end of the intake air pipe 19 is connected. The upstream end of an intake-air passage in the carburettor 21 is connected to an air-cleaner 22 disposed in a space within a fuel tank 16. Meanwhile, an exhaust pipe 23 is connected at its front end to the rear surface of the engine cylinder 20, and is prolonged at its rear end toward the lower rear part and connected to a muffler 24. Between the exhaust pipe 23 and the fuel tank 26 there is arranged a heat-insulation plate 25 for preventing the fuel tank 16 from being heated by radiant heat from the exhaust pipe 23. | ||||||
| 63 | Valve shaft sealing device of carburetor for internal- combustion engine with supercharger | JP15087881 | 1981-09-24 | JPS5853655A | 1983-03-30 | ITOU MITSUO |
| PURPOSE:To perform good sealing of a valve shaft in a well slidable state with bearing parts of a carburetor main unit supporting the valve shaft, by providing annular grooves in the periphery of the valve shaft and supplying pressurized air in the delivery side of a supercharger to said annular grooves. CONSTITUTION:Annular grooves 54A, 54B, at a face-to-face position to internally peripheral surfaces of bearing parts 48 in the inside of sealing members 52, are formed to a valve shaft 46 in a carburetor main unit 42. Though a pressurized mixture in an intake passage 44 tends to leak out to the atmosphere from between the peripheral surface of the valve shaft 46 and the internally peripheral surface of the bearing parts 48, the annular grooves 54 are provided and pressurized air is fed from a surge tank (not shown in the drawing), and internal pressure in the annular grooves 54 is higher than internal pressure of the intake passage 44. Accordingly, the pressurized mixture between the valve shaft 46 and the bearing parts 48 is pressed back into the intake passage 44 never to leak out to the outside. Further the pressurized air in the annular grooves 54 flows through the sealing members 52, even if slightly leaked out to the atmosphere, a bad influence is almost not caused, and the necessity for firmly pressing the sealing members 52 to the valve shaft 46 is eliminated, then slide resistance can be also decreased. | ||||||

| PURPOSE:To enable to avoid generating vibrations or the like due to combustion characteristic differences between cylinders by a method wherein throttle valves are provided respectively with passages of different sizes, in a multiple-type carbureter in which throttle valves for each carbureter are interlocked with each other. CONSTITUTION:In operation, air is sucked in through air intake passages 2a, 2b and is mixed with fuel which is supplied through main ports 6a, 6b. The resultant fuel-air mixture is introduced into scavenging chambers 4a, 4b through reed valves 3a, 3b, and the engine revolution speed is controlled by the throttle valves 10a, 10b. The valves 10a, 10b are rotated by a single shaft 11, so that the degrees of opening of the valves are equal. But at the time of idling, the amounts of air sucked in through the valves 10a, 10b are different from each other due to the opening-area difference between the through-holes 12a and 12b which are respectively provided in the valves 10a and 10b. Accordingly, in the case of an engine having differences in the length of suction or exhaust passages, the problem can be overcome, for example, by connecting the suction passage 2a having the larger through-hole opening area to a cylinder for which the passage is longer. | ||||||

| PROBLEM TO BE SOLVED: To continuously actuate an internal combustion engine even if a choke valve is closed as it is after the internal combustion engine is actuated by occupying the same starting position in an intake air duct at cold start time and ward shart time by the choke valve, and supplying combustion air of a quantity of a degree of maintaining an actuating condition after the internal combustion engine is actuated. SOLUTION: An internal combustion engine is arranged in a housing, and an ignitable air-fuel mixture is supplied to the internal combustion engine through a diaphragm carburetor 7. A starter 6 cooperates with a choke valve 11 and a throttle valve 12 rotatably arranged in an intake air duct 10 of the diaphragm carburetor 7 through a bar. An operation button 1 of the starter 6 is arranged in a gripping area of a rear grip. The starter 6 is arranged in the housing, and is used to stop the internal combustion engine by short- circuiting an igniter, and allocates a prescribed rotary position in the intake air duct 10 to the choke valve 11 and the throttle valve 12 in a starting position. Therefore, though the choke valve is closed, actuation can be maintained. COPYRIGHT: (C)1999,JPO | ||||||
