Abstract
The utility model relates to a lower than 3000-kilowatt two-stroke petrol-motored cut-off economizer, which includes a connecting flange (1). The connecting flange (1) is provided with an air inlet hole (11) matching with the outlet of the engine carburetor. The air inlet hole is arranged above the tapered valve body (2) of the connecting flange (1). At least one draught hole (21) opened on the tapered valve body (2), is arranged on a positive pressure closed leaf spring (3) on the air inlet hole (11). One end of the leaf spring (3) is fixed to the tapered valve body (2) and fitted over a pedestal (4) of the tapered valve body (2). An air outlet (41) that matches with the air inlet of the engine cylinder is provided in the middle of the pedestal (4). This economizer is arranged inside an air inlet of the engine cylinder, which not only avoids the regurgitation of the mixed fresh gas in the process of piston descending, but also reduces environmental pollution. According to the test, the economizer can save over 20% of the fuel. In addition, the economizer adopts a structure of the tapered valve body, which enables the output mixed gases from the engine carburetor to pass through the draught hole on the tapered valve body under negative pressure and directly go into a crankcase, instead of turning around for a plurality of times. This process improves the speed of air feeding and increases the air input, which accordingly, enhances the MPO (Maximum Power of Output) of the engine.

Embodiment
Shown in Fig. 1 to 10, the shutoff type fuel economizer of above-mentioned two-stroke gasoline engine below three kilowatts comprises adpting flange 1, and above-mentioned adpting flange 1 has the inlet hole 11 that matches with the engine and carburetor delivery outlet; Be contained in the cone valve 2 on the above-mentioned adpting flange 1, above-mentioned cone valve 2 has at least one airflow hole 21; The malleation that is contained on the said flow hole 21 is closed spring sheet 3, and an end and the above-mentioned cone valve 2 of above-mentioned spring sheet 3 are affixed; Be enclosed within the base 4 on the above-mentioned cone valve 2, the air outlet hole 41 that has the suction port with cylinder to match in the middle of the above-mentioned base 4; Above-mentioned base 4 not only is used for the connection of cylinder suction port, also be used to increase the length of cylinder intake passage, it is littler that the tapering of above-mentioned cone valve 2 is made, and can stretch into wherein, realization is littler from the combination gas resistance that Carburetor enters, and air inflow faster and more.Above-mentioned spring sheet 3 outsides are equipped with and are used to limit the excessive banking stop 5 of above-mentioned spring sheet 3 angle of releases, and the inclined angle alpha of the plane of above-mentioned banking stop 5 and above-mentioned spring sheet 3 is 5 ° to 30 °, and one end and above-mentioned spring sheet 3 or above-mentioned cone valve 2 are affixed.Airflow hole 21 exit faces on the above-mentioned cone valve 2 are the inclined-plane.If all there is airflow hole 21 above-mentioned cone valve 2 both sides, then two airflow hole 21 inclined-planes form sharp sword, and its resistance is littler, and is more unobstructed.Above-mentioned cone valve 2 also can be made an integral body with last base 4, installs more convenient.
Load onto fuel economizer of the present utility model between the cylinder air inlet of the shutoff type fuel economizer of two-stroke gasoline engine below three kilowatts and the Carburetor air outlet.The cylinder piston of this motor begins before the lower dead center operation from top dead center, the combination gas that has entered in the crankcase equates at cylinder air inlet passage, fuel economizer inner chamber, carburetor throat pressure, in the descent of piston process, the piston skirt is not before the shifter cylinder suction port, volume reducing in the crankcase, produce positive pressure, be connected on the cylinder air inlet spring sheet on the fuel economizer cone valve 23 and under above-mentioned positive pressure, close, prevent that combination gas is excessive through carburetor throat in the crankcase.The volume that prevents excessive combination gas depends on the height of piston stroke and cylinder pore.For example, the stroke of two-stroke gasoline engine (1E40F, 45F) is 40mm, cylinder intake hole height is 13mm, piston from top dead center to the lower dead center running, have approximately in the crankcase diameter of cylinder be 40mm, highly for the volume of the combination gas of 13mm not by excessive, the volume of this combination gas accounts for 30% of piston total kilometres.In the up process of cylinder piston, the crankcase inner volume increases, in crankcase, form negative pressure, this negative pressure is along with the height of piston stroking upward constantly increases, negative pressure is also along with increase, when cylinder air inlet is opened in the piston skirt, the spring 3 that is connected on the fuel economizer cone valve 2 on the cylinder air inlet is subjected to be opened by tapered shape under the above-mentioned suction function, cone valve 2 is very near from cylinder inner cavity, inhale the inlet hole 11 of combination gas on adpting flange 1 of coming from Carburetor, inclined-plane moment along cone valve 2 is broken through airflow hole 21, directly the air outlet hole 41 on base 4, cylinder air inlet enters crankcase fast.Because combination gas need not passed through about 180 ° the turning round of secondary in the Carburetor, directly enters crankcase, reduce the air inlet moment resistance, improve intake velocity, increased the combustion gas air inflow in the unit time, improve the performance of racing of the engine operation.For example, knapsack sprayer-duster is a power with the 1E40F two-stroke gasoline engine, according to the JB7235 standard code, 5000 rev/mins of its rated speed degree, when spraying higher crops, the jet pipe of atomizing sprayer need be inclined upwardly, will reach 5000 rev/mins of levels and spray range and atomizing effect this moment, must improve engine speed, its rotating speed should can meet the demands greater than 5500 rev/mins.Above-mentioned 1E40F two-stroke gasoline engine is loaded onto above-mentioned fuel economizer and is got final product.
