The generator output power increases --- as the load increases. The generator automatically increases the power output, the main engine governor operates (automatically), the throttle is increased, the oil intake is increased, and the main engine power output increases.
Increase the generator output voltage --- manual: adjust the excitation circuit potentiometer and increase the excitation current --- the voltage will increase
Automatic: with power output; As the voltage increases, the generator voltage may fluctuate. The generator's automatic excitation regulator operates to adjust the generator's excitation current so that its voltage remains virtually unchanged.
To drive an 800W tram, you need at least one generator capable of generating 1000W of electricity:
800/0.8=1000W (0 .8 is the efficiency of the tram)< /p>
If it isa piston carburetor, this is a typical phenomenon where the main oil needle falls. However, the generators are all general purpose gasoline engines with rotary valve butterflies. Gasoline must also be pumped behind the accelerator pedal (throttle opening is increased), but gasoline cannot be increased simultaneously.
As an experiment, cover the air inlet and the accelerator pedal with your hand. You should feel your hand being sucked in and, at the same time, gasoline should be sprayed into your palm. If the throttle can be increased in this way, the problem still lies in the oil level being too low or the main nozzle foam hole not being clear.
