小さい出方電流工ｌを出すようになっている。Assuming that the terminal voltage is constant during full excitation, the output characteristics of the generator (5) are initially 4#!, as shown by characteristic curve A in Figure 2. ! The output current increases as the rotational speed of the engine (1) increases.Furthermore, as the rotational speed of the internal combustion engine (1) increases, the rate of increase in the output current gradually decreases, and when the rotational speed exceeds a certain rotational speed. , the output current remains approximately constant regardless of an increase in the rotational speed of the internal combustion engine (1). Generally, the diameter ratio of the crank pulley (2) and the pulley (3) of the power generator @ (5) is set to approximately 2:1, so when the rotational speed of the internal combustion engine (1) is N1 during normal driving, , the maximum output current is reached, and the internal combustion engine near no-load (idle) operation (
1) At the low rotational speed N, the output current l is smaller than the maximum output.

If there is a load (7) that exceeds the output of 1 (5), the shortage will be supplied from the storage battery. If the amount of discharge caused by this is large, the end of discharge of the storage battery will be early, resulting in deterioration.
In some cases, the internal combustion engine (1) could not be started because the starter motor did not turn during startup due to insufficient electrical storage. In addition, when the electrical load is low during normal driving or high speed, the proportion of mechanical loss and iron loss that do not directly contribute to the output of the generator (5) increases, wasting the power of the engine (1), and further , at high speed, generator (5
) had the disadvantage of increased noise.
