JPH109087A FUEL INJECTION DEVICE FOR MODEL ENGINE 失效

摘要： PROBLEM TO BE SOLVED: To directly inject fuel to a combustion chamber, and stably supply fuel to a model engine the working condition of which is severe. SOLUTION: A solenoid coil 32 within a chassis 31 includes a magnetic core 34 provided with an air retaining space 35. A valve body 50 capable of being moved within the chassis 31 blocks a fuel injection port while being energized by a leaf spring 54. Fuel supplied from a fuel supply path 55 is retained in a fuel retaining space 56 in the chassis. The air retaining space 35 is blocked by an air control valve 39. The fuel injection port 43 is provided with a check valve 47. An air duct fixed to the valve body 50 is interposed between the air control valve 39 and the check valve 47. Air pressure is supplied to the air retaining space. When the coil is energized so as to allow the valve body 50 to be moved to the left, the fuel injection port 43 is released, and simultaneously the air control valve 39 is also released by the movement of the air duct 60. Fuel is atomized in a mist shape so as to be injected into the inside of a combustion chamber by air injected toward an injection nozzle 46 out of the air duct. Since the check valve is available, there is no fear of the reversely flowing of fuel due to high pressure within the combustion chamber.

摘要： PROBLEM TO BE SOLVED: To stably supply fuel in a model engine whose service conditions are severe. SOLUTION: A magnetic core 34 having a flow path 35 is inserted in a solenoid coil 31. A movable valve element 38 is set in the casing 32 in a casing 31. The valve 38 is energized by a plate spring 44 to close a fuel jetting port 37. A fuel supply path 48 is provided with a check valve 24. An air pressure supply path 25 and the inside of the casing 31 are partitioned with a diaphragm 26. The air pressure which is generated in a crank chamber and pulsates within the range of about 20-100kPa acts on the fuel in the casing 31 through the diaphragm 26. The air pipe 27 is fixed to the valve 38 and the diaphragm 26, and communicates the air pressure supply path 25 with a fuel injection port 37. The fuel led into a fuel injection device 30 is shut in by a check valve 24, and pressurized to fixed pressure by the pulsating air pressure sent from a crank chamber. At the time of injection, the air is jetted from an air tube to atomize the jetted fuel. The supply of the fuel is stabilized even under severe operating conditions, and a combustion efficiency therefore rises to improve the output of an engine.

摘要： PROBLEM TO BE SOLVED: To provide a pump used in a direct injection internal combustion engine. SOLUTION: A fuel amount regulation injection device for an internal combustion engine having a pump is indicated. The device comprises an air feed chamber to periodically change an air pressure in a room; a fuel feed chamber 12, and an operation chamber 14 related to the fuel feed chamber 12 and communicated with the air feed chamber so that an internal pressure is changed by a frequency corresponding to the fluctuation of an air pressure in an air feed chamber. The fuel feed chamber 12 is separated away from an operation chamber 14 by a pump member 4 to feed fuel to the fuel feed chamber 12 according to the change of a pressure in the operation chamber 14 and feed the fuel therefrom.
