Abstract
The utility model discloses a magneto of a motorcycle three-valve engine, consists of a coil (4) an igniting electrical source, a magnetic shoe, a triggering and igniting coil (1) and an iron induction block (2) at an outer ring of a rotator (5) of the magneto, and is characterized in that a central angle corresponded to an arc length of the induction block (2) is from 15 degrees to 19 degrees. A concluded angle between a centerline of the induction block and a centerline of a keyway is from 165 degrees to 180 degrees. A concluded angle between a rear edge of the induction block (2) and a center of the key way is from 0 degree to 6 degrees. The utility model adjusts and optimizes the pre-ignition angle jointly determined by the induction block and the triggering and igniting coil and the arc length of the induction block; enables a stable idle speed for the three-valve engine and an safe and allowable range for the deviation of the idle speed of the heat engine; also greatly enhances the reliability of starting up the cold engine.
Description
Technical field
The utility model relates to the motorcycle that adopts three-valve engine, specifically relates to the magnetogenerator of this three-valve engine.
Background technique
Motorcycle adopts three-valve engine can significantly reduce burning indoor exhaust air residual quantity, improves the power per liter and the power performance of motor.But existing three-valve engine but exists bigger problem in the use.Be embodied in: the big and cold machine of hot machine idling drift value starts difficulty.One of reason is that the igniting of this motor exists bigger mistaken ideas with magnetogenerator in the design of its irony sensor block, promptly all is the designs that design routinely, have even undertaken by the design principle of two-air valve engine exactly.
Summary of the invention
The purpose of this utility model is the design proposal that proposes a kind of irony sensor block of new magnetogenerator, to overcome the existing defective of three-valve engine in the prior art.
The magnetogenerator of a kind of motorcycle three-valve engine of this scheme, it comprises priming supply coil, magnetic shoe, igniting trigger winding and at the irony sensor block of magneto rotor outer ring.The axis of this magnetogenerator is coaxial with the bent axle of motor, determine the relative position of igniting trigger winding and described sensor block according to the top dead center position of engine piston, the pairing central angle of the arc length of this sensor block is 15 °～19 °, sensor block center line and keyway center line angle are 165 °～180 °, and the back edge of this sensor block is 0 °～6 ° with the angle at keyway center.
Superiority of the present utility model is as follows: existing three-valve engine ignored in design in the firing chamber of this motor mix gas more fully, waste gas residual few, from catching fire to very of short duration characteristics of the time of perfect combustion.And the utility model is adjusted and is optimized in the premature ignition angle of decision jointly with the igniting trigger winding arc length and this sensor block of sensor block just according to these characteristics.Make the three-valve engine idling stable, hot machine idling drift remains in the safe permission range; Simultaneously, the reliability of its cold machine startup also improves greatly.

Embodiment
A kind of magnetogenerator of motorcycle three-valve engine, it comprises that (habit claims: convex closure) for priming supply coil 4, magnetic shoe 3, igniting trigger winding 1 and the irony sensor block 2 in magneto rotor 5 outer rings.Magnetic shoe 3 is fixed in this rotor 5, and the axis of this magnetogenerator is coaxial with the bent axle of motor, and promptly magnetic shoe 3 rotates with rotor 5 and engine crankshaft simultaneously with described sensor block 2.Determine that according to the top dead center position of engine piston (this is conventional way for the relative position of igniting trigger winding 1 and sensor block 2, estimate and do not give unnecessary details), its adjustment and optimization part are: the pairing central angle of the arc length of this sensor block 2 is 15 °～19 °, the better effects if when wherein this central angle is 17 ° ± 0.5 °; Sensor block center line and keyway center line angle are 165 °～180 °, and effect was best when wherein angle was 171.5 °, and the back edge of this sensor block is 0 °～6 ° with the angle at keyway center.Better effects if when wherein angle is 3 ° ± 1 °.
Disclose so far, one of ordinary skill in the art can implement, so the working procedure of motor (containing igniting process) has not been given unnecessary details yet.Practice shows, presses the magnetogenerator of above-mentioned parameters optimization design, manufacturing, uses to produce a desired effect fully on the three-valve engine of being joined.
