Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, in figure: 1. fuel tank, 2. air filter is covered, 3. air filter seat, 4. Carburetor, 5. suction tude, 6. cylinder body, 7. spark plug, 8. baffler, 9. bent axle, 10. magnetogenerator, 11. piston, 12. Crank connected rod group, 13 crankcases, 14. oil nozzle, 15. jet pipe, 16. main jet, 17. main jet hydraulic fluid port, 18 Carburetor passages, 19 suction tude mixed gas gas-entered passageways, 20. one-way valve, 21 suction tude passages, 22. accumulator, 23. scavenging air belt, 24. cylinder port, 25. firing chamber, 26. Carburetor aditus laryngis, 27. suction tude aditus laryngis, 28. suction port.
It mainly is comprised of fuel tank, air filter lid, air filter seat, Carburetor, suction tude, cylinder body, spark plug, baffler, bent axle, magnetogenerator, piston, Crank connected rod group, crankcase, oil nozzle, jet pipe.The main oil inlet passage of first of petrol engine is that the main jet hydraulic fluid port on Carburetor is connected with suction tude mixed gas gas-entered passageway on suction tude, then be connected to accumulator on cylinder body by one-way valve, in accumulator, oil nozzle is housed simultaneously, the jet pipe in addition that is communicated with accumulator simultaneously, suction tude pipeline communication on the jet pipe the other end and suction tude, the suction tude passage is communicated with cylinder channel on cylinder body, and then is communicated with crankcase.The effect of this passage is to provide negative pressure and injection power is provided during for oil spout.Second main passage of the machine is that the Carburetor passage on Carburetor is communicated with the Carburetor aditus laryngis, then is communicated with the aditus laryngis of suction tude, is connected to crankcase by the suction port on cylinder body at last, and this passage is controlled by the piston skirt and opened and closed.
The utility model low emission small two stroke gasoline working procedure is as follows:
Fuel oil enters into Carburetor by the main jet on Carburetor, be divided into two passages, most of fuel oil enters suction tude mixed gas gas-entered passageway on suction tude by the main jet hydraulic fluid port, and the one-way valve of then inlaying through suction tude mixed gas gas-entered passageway end enters temporary transient storage the (this one-way valve guarantees that fuel oil can only flow from Carburetor to the cylinder body direction) in the accumulator of cylinder body.In accumulator, oil nozzle is housed simultaneously, the size of oil nozzle can be adjusted according to the discharge capacity of motor, and oil nozzle is born the effect of oil spout direction and injection pressure simultaneously, and oil nozzle finally is connected with the firing chamber of cylinder body, and it is controlled by piston and opens and closes.Rapidly the fuel oil in accumulator is brought in jet pipe after piston is opened accumulator when the high temperature that produces from the cylinder body internal combustion, high pressure draught and heats, air-flow arrives suction tude passage on suction tude along jet pipe, arrive at last piston and return by former road when encountering piston, so piston was in the bottom dead center position oil nozzle and was in open mode this moment, fuel oil has just injected under the effect of air-flow in the firing chamber of cylinder body prepares work by combustion.Piston continues up by lower dead center, produce negative pressure in the pump-absorb action lower crankcase of piston, negative pressure is delivered to the suction tude passage by the cylinder port on cylinder body, and then arrival jet pipe, jet pipe passes to Carburetor through suction tude mixed gas gas-entered passageway with negative pressure again by accumulator and one-way valve, be that Carburetor oiling again produces power resources, thus temporary fuel oil in the accumulator again on cylinder body, for next work cycle ready.A little fuel oil is through the passage on Carburetor in addition, mix with air after entering the Carburetor aditus laryngis, by the aditus laryngis above suction tude, enter the motion assemblies such as crankcase lubrication crankshaft-link rod by the suction port on cylinder body, entering finally by two scavenging air belts on cylinder body will not have the waste scavenging of emptying clean after burning in the cylinder body firing chamber again.
