That is, as shown in Fig. 20, when the engine is stopped, the piston has a high probability of stopping in the compression operation just before reaching the compression top dead center (TDC). When the starter motor 49 is driven in this state when the next engine is started, the engine will not ignite at the engine position before the next compression TDC, but will burst before the next compression TDC. Therefore, the starter motor 49 must rotate the engine at least when the piston compresses Tdc by the next time after the j engine is started. When the piston reaches the vicinity of the next compression TDC under the start of the engine, if the starter motor 49 is stopped, the explosion will increase in the reverse direction and the crankshaft will be reversed, so that a so-called pressure burst occurs.

OV . The charging restriction unit 50 5 at the time of the start, in addition to responding to the start detection pulse, starts a 7-second timer 50 5a. When this timer 505a expires, or the number of rotations Ne is equal to or greater than the set number of rotations, or the throttle is opened. When the degree is reduced, the charging limit is lifted and the charging voltage is returned to 14.5V from 12 · ν. According to this charging control, if the cyclist quickly opens the throttle and accelerates quickly when the vehicle is started or stopped, the charging voltage is reduced to temporarily reduce the electrical load of the generator 44. Therefore, reducing the mechanical load on the engine 20 () by the generator 44 improves the acceleration performance.
