一问:为什么同一辆摩托车,夏季与春秋季的动力存在明显差异;相同排量的发动机相比,动力有着明显差异,问题出在哪里?如何解决?答:这个问题有点含糊,也比较笼统,在解答问题之前,我们首先要搞清楚动力与发动机技术参数的关系。从技术角度上说,发动机的动力与气缸排量、活塞行程、曲轴转速、压缩比、配气相位、点火提前角、功率、 I asked why: the same motorcycle, there are significant differences between the power of summer and spring and autumn; the same displacement compared to the engine, there are significant differences in power, the problem lies in what? How to solve? A: This issue is a bit vague, but also more general Before answering the question, we must first understand the relationship between engine power and technical parameters. From a technical point of view, the engine power and cylinder displacement, piston stroke, crankshaft speed, compression ratio, gas phase, ignition advance angle, power,
