Problems solved by technology
The emergence of digital igniter has brought two technical problems: one is the extraction of the optimal ignition advance angle parameters; due to different engine speeds and loads, the optimal ignition advance angle varies greatly for different types of engines , and the change rule is complex; therefore, a device that can easily change the ignition advance angle is needed to extract the ignition advance angle parameters of the engine
The second is that the timing curve of the digital igniter required by the engine is complex, and for different types of engines, the ignition curves are very different and incompatible; a convenient method is needed to program the timing curve of the igniter so that the igniter becomes a A digital igniter that can be programmed online to facilitate popularization and application

Description
technical field [0001] The invention relates to a programmable and readable digital igniter for motorcycles and a programming system for online programming of the ignition advance angle of the igniter. Background technique [0002] The initial motorcycle engines all used an igniter with a fixed advance angle. This igniter can only make the engine work in the best working state under a certain condition, and cannot effectively improve the operating efficiency of the engine. With the advancement of technology, a simple analog timing electronic igniter was adopted in the early 1980s, which can simply adjust the ignition advance angle according to the change of the engine speed. This improvement also cannot meet the engine's requirements for changes in the ignition advance angle. In fact, the optimal ignition advance angle of the engine is not only related to the speed, but also related to the engine load, throttle opening and other factors. Thus, in recent years, microcomputer...
