点火提前角的大小,对发动机性能有直接的影响。当发动机处于最佳点火提前角时,其动力性、经济性,都具有最佳的数值。那么,多大的点火提前角才能算最佳的点火提前角呢? 点火提前角,它与转速和负荷有关,在实际工作中,发动机的转速和负荷是经常变化的,所以点火提前角也是一个变化量。从 Ignition advance the size of the engine performance has a direct impact. When the engine is in the best ignition advance angle, its power, economy, have the best value. So, how much ignition timing can be considered the best ignition advance angle? Ignition advance angle, it is related to speed and load, in actual work, the engine speed and load are constantly changing, so the ignition advance angle is a change the amount. From
