Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Fig. 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. pistons, 12. Crank connected rod groups, 13 crankcases, 14. oil nozzles, 15. jet pipes, 16. main jets, 17. main jet hydraulic fluid ports, 18 Carburetor passages, 19 suction tude mixed gas gas-entered passageways, 20. one-way valves, 21 suction tude passages, 22. accumulators, 23. scavenging air belts, 24. cylinder ports, 25. firing chambers, 26. Carburetor aditus laryngis, 27. suction tude aditus laryngis, 28. suction ports.
It is mainly 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.First main oil inlet passage of petrol engine is that the main jet hydraulic fluid port on Carburetor is connected with the suction tude mixed gas gas-entered passageway in suction tude, then by one-way valve, be connected to the accumulator on cylinder body, in accumulator, oil nozzle is housed simultaneously, jet pipe in addition simultaneously that be communicated with accumulator, suction tude pipeline communication in the jet pipe the other end and suction tude, suction tude passage is communicated with the 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 Carburetor aditus laryngis, then is communicated with the aditus laryngis of suction tude, finally by the suction port on cylinder body, is connected to crankcase, and this passage is controlled and opened and closed by piston skirt.
Low emission small two stroke gasoline working procedure of the present invention is as follows:
Fuel oil enters into Carburetor by the main jet on Carburetor, be divided into two passages, most of fuel oil enters the suction tude mixed gas gas-entered passageway in suction tude by main jet hydraulic fluid port, and the one-way valve of then inlaying through suction tude mixed gas gas-entered passageway end enters interior temporary transient storage of accumulator (this one-way valve guarantees that fuel oil can only flow from Carburetor to cylinder body direction) of cylinder body.In accumulator, oil nozzle is housed, the size of oil nozzle can be adjusted according to the discharge capacity of motor simultaneously, and oil nozzle is born the effect of oil spout direction and injection pressure simultaneously, and oil nozzle is finally connected with the firing chamber of cylinder body, and it is controlled and opened and closed by piston.Burning produces in from cylinder body high temperature, high pressure draught are brought into the fuel oil in accumulator in jet pipe and heat rapidly after piston is opened accumulator, air-flow arrives the suction tude passage in suction tude along jet pipe, finally arrive piston and return encountering piston Shi Anyuan road, so now piston is in bottom dead center position oil nozzle in open mode, fuel oil has just injected in the firing chamber of cylinder body under the effect of air-flow prepares work by combustion.Piston continues up by lower dead center, in the pump-absorb action lower crankcase of piston, produce negative pressure, negative pressure is delivered to 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 by negative pressure again by accumulator and one-way valve, for Carburetor again oiling 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, after entering Carburetor aditus laryngis, mix with air, by the aditus laryngis above suction tude, by the suction port on cylinder body, enter the motion assemblies such as crankcase lubrication crankshaft-link rod, finally by two scavenging air belts on cylinder body, entering cylinder body firing chamber will not have the waste scavenging of emptying clean after burning again.
