The coil of described first charge coil winding is more than the coil turn of the second charge coil winding.Because the first charge coil winding is that storage battery (storage battery) charges and connects external load charging, power demand is large so the number of turn is many; Second charge coil winding is only for carburetor electromagnetic valve is powered, and power demand is little, then the number of turn is few.
The magnetic pole of described rotor is arranged on the flywheel of engine.The magnetic induction line producing motion is rotated together, the magnetic induction line generation current of fixing stator coil cutting movement by the flywheel rotor driven of engine.
Accompanying drawing explanation
Fig. 1 is circuit theory schematic diagram of the present invention.
In accompanying drawing: 1 is rotor, 2 is stator, and 3 is the first charge coil winding, and 4 is the second charge coil winding, 5 is the first rectification circuit, and 6 is the second rectification circuit, and 7 is control unit, and 8 is storage battery, 9 is external load, and 10 is carburetor electromagnetic valve, and 11 is stator core, and 12 is gasoline engine.
Specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Shown in Figure 1, a charging system for gasoline engine, comprise and be arranged on rotor 1 on gasoline engine 12 and stator 2, the magnetic pole of described rotor 1 is fixedly mounted on the flywheel of gasoline engine, magnetic pole is contained on flywheel follows bent axle to rotate relative to crankcase, and described rotor 1 adopts external rotor.The stator core 11 of described stator 2 is contained on gasoline engine casing, stator core 11 is wound with respectively the first separate charge coil winding 5 and the second charge coil winding 6, the coil of described first charge coil winding 5 is more than the coil turn of the second charge coil winding 6, the storage battery connected because of the first charge coil winding 5 is relative with external load power large, the carburetor electromagnetic valve power that second charge coil winding 6 connects is relatively little, so the coil of the first charge coil winding 5 is more than the coil turn of the second charge coil winding 6.The coil of the first charge coil winding 5 needs to determine according to power output than the more few circle of the coil of the second charge coil winding 6.
First charge coil winding 5 and the second charge coil winding 6 are electrically connected with a rectifier, and described rectifier is provided with the first rectification circuit 5 and the second rectification circuit 6, two rectification circuits are independently arranged on one piece of circuit board, and not in parallel between two rectification circuits.Two rectification circuits are integrated on one piece of circuit board, decrease the setting of parts, are not only convenient to be arranged on gasoline engine, and saved cost.Described first rectification circuit 5 adopts the rectification circuit of existing full-wave rectification, and the second rectification circuit 5 adopts the rectification circuit of existing halfwave rectifier.
