摘要： PROBLEM TO BE SOLVED: To prevent the deterioration in service life durability of a two-cycle engine and a work machine due to overspeed of the two-cycle engine, make engine rotating speed constant, and realize an effect similar to a rotating speed stabilizer such as a throttle governor with a simple structure. SOLUTION: In a two-cycle engine which has a float type carburetor 6 and drives a work machine, pressure air is introduced to a float chamber 22 in an overspeed area so that a generating air-fuel mixture exists in the vicinity of the theoretical air-fuel ratio in an ordinary rotation area and becomes dense in the overspeed area, and overspeed can be prevented.

摘要： PURPOSE: To rationally and effectively perform automatic correction of the composition of supply mixture by blocking the lower end of a second vertical pipe by the bottom surface on which a calibrated hole penetrates, and forming a through hole on the second vertical pipe at a level higher than the constant level of a fuel container. CONSTITUTION: When the intake flow F is allowed to flow through an intake air adjusting device D, suction to a supply pipe 1 positioned in the small-diameter sectional part R of the device D is generated. The some amount of gasoline is sucked from a fuel container V through a calibrated hole 19 on the bottom surface 18 of a second vertical pipe 16, a cerebration nozzle 13, and a first vertical pipe 4 by the suction action and diffused into the device D through the supply pipe 1. Since this gasoline flow receives a head loss by the resistance of the calibrated hole 19, the gasoline level in a gap 20 is the liquid level M lower than the liquid level L of gasoline in the container V. To be precise, as the gasoline flow to be allowed to flow through the calibrated hole 19 is increased, the liquid level M is lower than the liquid level L, and the supply gasoline amount to be determined by the nozzle 13 is a function of pressure reduction in the small-diameter sectional part R of the device D and a water head to be received by the nozzle 13.

摘要： PURPOSE:To surely supply starting fuel by an inexpensive system in small size with no necessity for a power source by constituting a device introducing a positive pressure of pulsation, generated in a crankcase before complete explosive combustion of an engine, to a float chamber and pressurizing fuel. CONSTITUTION:An air vent passage 14, connected to an inlet of an intake passage 5, is opened to the upper part of a float chamber 6, and a selector valve 18 is provided halfway the passage 14. A pressure introducing passage 17, opened to a crankcase 16 of an engine 15, is connected to the selector valve 18. In a low negative pressure before complete explosive combustion of the engine 15, a valve 20 closes an atmospheric side passage part 14a by tension of a spring 27, connecting the pressure introducing passage 17 to a float chamber side passage part 14b. A check valve 31 is provided in the pressure introducing passage 17, and introducing only a positive pressure of pulsation to the float chamber 6 pressurizing fuel to be depressed in its oil level L-L, a mixture in the time of starting obtains high concentration.

摘要： PURPOSE:To supply the optimum mixed gas in accordance with the loaded state by connecting the turning shaft of an air control valve for varying the vent area of a venturi part by the turning operation, in interlocked state, with a negative-pressure operating mechanism operated by the negative pressure of the venturi part. CONSTITUTION:When an air control valve diaphragm 12 is operated by the variation of the negative pressure in a venturi part 4, an air valve 5 maintains the proper opening degree in proportion to the negative pressure. In engine idling, fuel is jetted out only from a bypass hole 15 and an idle hole 16. Further, in the intermediate loading of the engine, the air valve 5 operates so that the optimum vent area in that operation state can be obtained, and fuel is jetted out from the primary main nozzle 20, and the optimum mixing ratio can be obtained. Further, though the intake air quantity increases in high loading, since each opening degree of a throttle valve 3 and the air valve 5 is large, the optimum output mixed gas can be obtained, since the secondary main nozzle 24 assists the fuel injection quantity. Therefore, the optimum output mixed gas can be supplied in accordance with all the loading states of the engine.
