in the meantime, the converter solution 12> 220 connected to the vehicle must work ?!
by cotnre must buy a converter worthy of the name, I tried on a fridge / freezer 100W of consumption, with a PC inverter connected to a car battery, as soon as I opened the door the 2 fuses 30A blown !
from the start of the fridge / freezer compressor motor. condenser dirt! apparently it gets around with a choke upstream, taken on the primary of a transformer of power equal to the desired consumption, which is not obvious ... otherwise you have to take a BIG converter!
I bought a 200 € for a 2000W (supported 4000 in crete) pseudo-sinus (worked well on everything, except on eco lamp it hissed a little, but there are filters ??) on the soft energy store of ebay ...
hey yes a car engine it works well already: we even have hot water! just recover the hoses from the passenger compartment heating system (or connect a T) ...
with a multimeter connected to the battery you can see if it fails and adjust the engine idle speed accordingly ... well it will heat up but as said above, just cool by extending the cooling circuit, especially if there is no fan that triggers automatically; the best being to connect one to a strap like the perkins ...
I think we can not use the air conditioning either, but we must be able to add several alternators on the belt ... obviously the engine would run on oil, diesel indirect injection bosch pump injectors 185 bars pre-wash pump electric reheater before the GO filter, and we can pantonize it.
on direct injection be careful if the engine is not loaded, at idle, it will actually clog if the exhaust T ° C, representative of the load, is not at least 300 ° c ... on indirect ok it goes up well ;-)
to make 220: you have to find a three-phase asynchronous motor, they have a "squirrel cage" ie an output grid for cooling no doubt.
example: if the motor consumes on 380V 1500W to run at 1400 rpm, info given on the motor plate, then its synchronism speed is 1500 rpm (there are 600, 1000, 1500 and 3000 ...) it will suffice to run this same engine at 1500 + (1500-1400) = 1600 rpm with the internal combustion engine for it to produce 380V! thus with a star connection of capacitors on the triangle phase connection will allow 3 times 1500W on 220V. the calculation of the capacitors is done here:

WARNING !!!!
As soon as the generator has reached synchronous speed and can produce energy, it MUST BE CONNECTED TO A LOAD !!!! resistance or network. Otherwise the wind turbine may run away because it will not be "Restrained" by the generator !!!!
"
otherwise you can also connect the engine to the network, it will not consume but will produce.
in short an old engine can be useful!
