Description

Motorcycle electric spraying system magneto ignition advancer

Technical field

The present invention relates to a kind of motorcycle ignition device, particularly a kind of motorcycle electric spraying system magneto ignition advancer.

Background technology

Motorcycle with electronic fuel injection system electronic-controlled ignition system, by ECU ECU(ignition procedure controller) according to the operating condition adjustment of each sensor signal and gasoline engine with control ignition advance angle, make the performance of the aspect such as dynamic property, economy, discharge of engine reach preferable states. But different engines have under different operating conditions and different condition, Optimum spark advance angle is to the greatest extent not identical yet. Optimum spark advance angle is relevant with factors such as engine speed loads. Be that engine speed is higher, Optimum spark advance angle should be larger; Engine load increases, and Optimum spark advance angle should reduce. But Optimum spark advance angle is all nonlinear with rotation speed change with the variation of load. Be that better points fire advance angle changes within the specific limits, that is to say that what way to select best ignition advance angle by is all most critical. The existing electric injection system magneto of example, five 9 of sheep Honda 110T-2 electric spraying magneto periphery induction points, the magneto periphery induction point of the fast hawk money of sundiro Honda electric spraying magneto and Yamaha electric jet vehicle is 11 all to be fixed, some induction pistons will arrive top dead centre, lower dead center and piston and start up and down induction point, igniting induction point and other operating mode induction point etc., induction oil spout, igniting. Although electronics, electronic control ignition system can make advance angle of engine ignition approach desirable ignition advance angle with rotation speed change with the variation key of load, but still are not best.

Summary of the invention

Object of the present invention is that a kind of motorcycle electric spraying system ignition by magneto advance angle of invention can raise and increase, reaches not only large, noxious gas emission but also few motorcycle electric spraying system magneto ignition advancer of not only fuel-efficient power with engine speed.

Motorcycle electric spraying system magneto ignition advancer of the present invention, it is characterized in that the fixed ignition induction point that magneto is responded to mutually in engine compresses stroke rotor subject and crankshaft sensor changes the induction point of disjunctor activity into, a return little spring and a little curved conductor of fixed installation are installed before the movable induction point of disjunctor, little curved conductor is bent to the back of the body capping edge of magneto rotor main body, before little bending iron conduit, fixedly mount again a large curved conductor, large curved conductor other end sealing, a return big spring and string are housed in blind end the wire digging line of steel ball, last steel ball is fixedly connected with wire digging line, other steel ball can be movable on wire digging line, return big spring heads on last steel ball, wire digging line is through little curved conductor and little return spring, be fixedly connected with the movable induction point of disjunctor. in order to keep the dynamic balancing of magneto rotor main body, can adopt in two ways, the one, be equipped with at the symmetrical place of the large curved conductor of magneto rotor main body back of the body capping one with the large curved conductor of counterweight of curved conductor same specification greatly, conduit closed at both ends, in conduit, be also equipped with steel ball that wire digging line is gone here and there with quantity with the counterweight steel ball of diameter and a counterweight return big spring same with return big spring. the 2nd, adopt the method for boring, attenuate or other weight reductions, the dynamic balancing that keeps magneto rotor on one side at the large curved conductor of magneto rotor main body.

Apparatus structure of the present invention is simple, not easy to wear, durable. Load onto device of the present invention, when motorcycle engine rotating speed high, all steel ball moves backward, all springs by compression, before wire digging line pulls to movable disjunctor igniting induction point, so just reach along with the rotating speed suitable advanced ignition that raises, obtain Optimum spark advance angle, reach the better moment of igniting, make mixture combustion more fully more complete, reduce the discharge of waste gas and pernicious gas. Thereby make motorcycle starting fast, acceleration is good, reach more fuel-efficient, more environmental protection, more powerful, the starting effect faster that raises speed.
