Magneto Advance Ignition Device for EFI System of Motorcycle

Abstract

The invention discloses a magneto ignition advancer for a motorcycle electronic fuel injection system. The magneto ignition advancer is characterized in that a fixed ignition induction point, induced with a crankshaft sensor, of a magneto rotor body is changed into a connection motion induction point, a small return spring and a small bent guide pipe are fixedly installed in the front of the connection motion induction point, the small bent guide pipe is bent to the edge of the back cover face of a magneto body, a large bent guide pipe is fixedly installed in the front of the small bent guide pipe, the other end of the large bent guide pipe is closed, a large return spring and a steel wire inhaul cable with steel balls in series are installed inside the closed end, the last steel ball is fixedly connected with the steel wire inhaul cable, the other steel balls can move on the steel wire inhaul cable, the large return spring abuts against the last steel ball, and the steel wire inhaul cable penetrates through the small bent guide pipe and the small return spring and is fixedly connected with the connection motion induction point. Movable balance of the magneto rotor body is kept in two modes. The magneto ignition advancer is simple in structure, not prone to abrasion, and durable. A motorcycle can save more oil, and is more environmentally friendly, larger in power and faster in starting speed increase.

Description

technical field [0001] The invention relates to an ignition device for a motorcycle, in particular to a magneto advance ignition device for an electronic injection system of a motorcycle. Background technique [0002] The electronic control ignition system of EFI motorcycle is based on the electronic control unit ECU (ignition program controller) to adjust and control the ignition advance angle according to the signals of various sensors and the operating conditions of the gasoline engine, so that the engine's power, economy, emissions, etc. performance at its best. However, different engines have different operating conditions and different conditions, and the optimal ignition advance angles are also different. The optimal ignition advance angle is related to factors such as engine speed and load. That is, the higher the engine speed, the greater the optimum ignition advance angle should be; the increase in engine load, the optimum ignition advance angle should be reduced...

AI Technical Summary

Problems solved by technology

Although electronic and electronically controlled ignition systems can make the ignition advance angle of the engine change with the speed and load, the key is closer to the ideal ignition advance angle, but they are still not optimal.
