GT120THU is equipped with a 200W generator and starting system. It is horizontally-opposed two-cylinder engine, which has less vibration compere to single cylinder engine of the same displacement. Its regulate rectifier is open type, which has less friction loss. Conventional Shunt regulate rectifier continuously emits surplus electricity converting to heat, which is nothing but waste. Permanent magnet generators generate electricity in proportion to engine rpm, so Shunt regulate rectifier is concerned to break down during continual high rpm operation. To overcome the issue, we have developed open type regulate rectifier corresponding to wide range input voltage. The new regulate rectifier regulates the output electricity according to input voltage and the output voltage coming from the DC converter. (Patent pending) The generator supplies only the needed electricity constantly over a wide rpm range, so mechanical friction loss is reduced improving fuel mileage with good response. Its starting system is consists of a brush motor and a relay switch. It works more than 10 times using 3-cell Li-Po battery (2,200mAh/45C). Generator, regulate rectifier, throttle/choke servo are integrated in one unit.
