The piston 15 drives a flywheel 16 having a plurality of coded teeth 161 and an empty tooth (6) as the jet engine 11 continuously rotates between intake, compression, explosion, and exhaust, and the rabbit "Γ^ Αλ In order to stabilize the power of the wheel, the prior art uses the sensor 17 to detect the coded teeth 161 and the empty teeth 162' of the periphery of the flywheel 16 to obtain the ripple signal 18 as shown in FIG. The corrugated signal 18 has a plurality of encoded tooth signals ΐ8ι corresponding to the code 胄161, and a reference tooth signal 182 corresponding to the empty teeth 162. Referring to FIGS. 1 and 2, after determining the reference tooth signal 182 of the corrugation signal 18, the electronic control unit 13 will assign the coded tooth signal (8) to the fuel injection device 13 to ignite the ignition device 14. At the time point 'the corresponding injection signal 131 and the ignition signal 4' are generated, and the intake, compression, explosion, and exhaust operations can be completed once every two revolutions of the flywheel 16 to generate power. Since the 5 hp jet engine 11 is only two turns (720 s) after the flywheel 16 turns, the 201233894 will complete the intake, start, and κ processes. When the medium power 'jet engine u, the two ^V82, therefore 'At the start of the spray 182, but can not be judged - Second, although the reference tooth signal can be accumulated in the explosion row 5 engine - 11 is in the intake, compression, explosion, milk discharge in which stroke. Therefore, when the jet engine 11 is started, the injection device 13 is controlled: the ignition device 14 injects and ignites one revolution of the flywheel W, and the flywheel 16 rotates the coil device 13 per revolution. It is 1/2 of the oil that is required to inject the jet engine 11; / , . . . , so that the jet engine u is rotated two times after the flywheel 16 is turned ▲ to obtain the complete oil amount 'to maintain the The jet engine 11 has an appropriate air/fuel ratio (the ratio of air to fuel). =. The jet engine "must determine the reference tooth signal 182 of the corrugation signal ,, and then give the coded tooth signal 181 number ' to determine the timing of the ignition of the injector 13 and the ignition device 14 so that it is easy The time point at which the first injection of the injection device 13 occurs (shown by a broken line in FIG. 2) falls before the reference tooth signal 182 without being injected, thereby causing the ignition device 14 to fail to ignite at the ignition time. In other cases, since the nozzle device 13 only sprays the 1/2 of the amount required by the jet engine η at startup, the air-fuel ratio is too thin, and the ignition device 14 is unlikely to be ignited smoothly when ignited or Because the jet engine 11 completes the compression, explosion, and exhaust of the intake air once after two revolutions of the flywheel 16 to generate power, therefore, whether the fuel is not injected, the ignition cannot be smoothly performed, or Insufficient power, the ignition device 14 must have another chance to ignite the mixture of the amount of oil sprayed by the injection device 13 of the 201233894 after the flywheel 16 is rotated two more times, as shown in Figure 2 for the third time. Fried top dead center to start, not only of the poor start (start time is too long), will accelerate the consumption of battery power. SUMMARY OF THE INVENTION Therefore, the purpose of this invention #, that provides a method for starting -⑽ rainbow four-stroke engine.

The first injection ignition step is to control the amount of oil that corresponds to the air-fuel ratio at the reference tooth position, and control the spark plug to ignite at a set coded tooth position. And the first injection ignition step is that the fuel nozzle starts to inject the oil corresponding to the air-fuel ratio at the reference tooth position within one time of the rotation of the toothed disc, and controls the spark plug to ignite at the set coded tooth position. The trip step is to use the electronic control unit to determine that the electronic control unit of the single-cylinder four-bow engine can determine the single-red four-stroke under-injection I:: enter the normal operation step 'If not, return to the first • Human jet ignition step. Fuel = : The amount of oil that is controlled by the person to fire the air-fuel ratio is controlled within two weeks of the rotation of the toothed disc, and the control _ spark plug 201233894 is ignited at the set coded tooth position. The invention has the beneficial effects of controlling the fuel nozzle to respectively inject the oil quantity corresponding to the air-fuel ratio and the oil quantity corresponding to the air-fuel ratio in the first injection ignition step and the second injection ignition step by using the reference tooth position. The electronic control material a can quickly determine the stroke position of the Xiao single-cylinder four-stroke engine, effectively shortening the startup time to improve the startability and reduce the power consumption. The above and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. The ignition step 22 of the start-up method of the single-cylinder four-stroke engine, and the second nozzle shot are shown in FIG. 3 and FIG. 4. The preferred embodiment of the present invention includes a first injection ignition step 23, a stroke determination step 24, and a Normal operation step 25. And the starting method is to use the position sensor 3H to measure the -ring 33 disposed on the crank 32, and to control the fuel nozzle 35 and the Mars with the electronic unit 34 electrically connected to the position sensor 31. The opening and closing of the plug %, the disk 33 has a reference tooth 331 ' and 23 teeth opposite to the tooth 332 of the reference tooth state. In the preferred embodiment, the electronic control unit 34 electrically connected to the position sensor 31 is used to calculate a continuous square wave corresponding to the reference tooth 33ι and the code #332 as shown in FIG. The large ripple is representative of the position of the reference tooth 331, and the small ripple of the distance is representative of the position of the coded tooth 332. Referring to FIGS. 3, 4, and 5, the first injection ignition step 22 is when the position of the reference tooth 331 is located at 201233894, the electronic control unit output, the fuel injection signal 341, controls the fuel nozzle 35 to start emitting. The ratio of the amount of oil' and the electronic control of the Tsui-Yuan 34 is outputted by a magnetization point 342 to control the spark plug 36 for ignition. The setting of the moiré 332 is spaced from the reference tooth 331 by w. The rear coded teeth l thereby ensure that the fuel nozzle 35 can eject the air-fuel ratio before the spark plug 36 enters (four) fire. In the preferred embodiment, the set coded teeth 332 # are disposed as spacers 120 of the spot reference teeth 331. After the editor said, and the electronic control list = 34 is to (4) the fuel nozzle 35 (four) (four) heart control the amount of oil. And the second injection ignition step 23 is performed by the electronic control unit 34 during the one-week (360) rotation period of the toothed disc 33 (4) and the charging control "342 control _ fuel 対% The reference gear is set to start 1/2' of the fuel amount of the burner fuel ratio and the spark plug 36 is controlled to ignite at the position of the set coded tooth 332. Thereby, it is not possible to reduce the consumption of the oil amount, and it is also ensured that the amount of oil discharged by the second injection ignition step 23 enters the stroke of the next intake. The trip determination step 24 is to use the electronic control unit 排气 to vent: If the electronic control unit 34 can determine that the single-cylinder four-stroke engine king enters the normal operation step 25, if not, return to the Stage: Ignition step 23. This normal operation step 25 is at the sprocket 2 port. The time period 'by the electronic control unit 34 outputting the target injection 201233894 signal 341 and the magnetizing ignition signal 342 to control the combustion (four) nozzle 35 to eject the air-fuel ratio ϋ control 该 control the spark plug% The stone horse teeth 332 position is ignited to generate a power output once. It should be particularly noted here that the electronic control unit 判断 determines that the single-cylinder four-row engine is in the middle of the stroke, and is not described in detail in the prior art of the art. If the reference tooth 331 in the first injection ignition step 22 is before the top dead center of the intake air, when the magnetization ignition signal 342 in the first injection ignition step 22 activates the spark plug 36, The single-row four-stroke engine is in the intake stroke, so it is impossible to ignite the sprayed oil I to the engine. However, this means that the reference tooth 331 in the second injection ignition step 23 is before the top dead center of the explosion, and therefore, the amount of oil sprayed by the second injection ignition step 23 can be matched with the intake air. The upper dead mixed compression forms the oil and gas, so when the magnetizing ignition signal 342 of the second injection ignition step starts the spark plug 36, the oil and gas starting engine can be ignited, and the electronic control in the stroke determining step 24 is performed. After two explosions, the unit can determine that the single-cylinder four-stroke engine is in the intake pressure, and the n-stroke effectively shortens the starting time to improve the startability and reduce the power consumption. If the reference tooth 331 of the first injection ignition step 22 is at the top dead center of the explosion, since the amount of oil discharged is not mixed with air, the magnetization ignition signal in the first injection ignition step 22 342 still can not ignite the amount of oil sprayed. 201233894 thus means that the reference tooth 33 1 in the second injection ignition step 23 is before the intake top dead center, so when the second injection ignition step 23 the magnetization ignition signal 342 starts the spark plug At 3 o'clock, since the single-cylinder four-scheduled engine is in the intake stroke, the engine cannot be ignited by the &, and the engine is started, but when the second injection is performed, the second injection ignition step is performed. At 2300, at this time, the reference tooth 331 is before the top dead center of the explosion, and the amount of oil sprayed is exactly the same as the amount of oil sprayed from the second injection ignition step 23 of the first time. The amount of fuel burned, so, the number
