I've never heard of anyone trying that. The problem with a diesel car engine is that they normally have a limiting speed or automotive style governor, meaning that it won't control engine speed all that well with a varying load.
That's something silvermachine will have to look into on that ebay engine if they plan on using it. IDK what style governor it uses.
To create AC power from a generator head, You'll need a variable speed governor or isochronous governor(typically expensive), otherwise your frequency will be unstable and that can mess/ruin stuff quickly.
Look up auxiliary power units for semi trucks. Those are all diesel powered and create heat/ac, 12v DC power, and some also have the option to create AC power as well.
On my apu turned generator, I eliminated the a/c compressor and heater loop so it only drives the AC generator and DC alternator. I wanted to be able to run the a/c on shore power if it was present, so I installed a rooftop ac unit which made the compressor unnecessary. I might hook the heater loop back up though if I ever want to cold camp. All it is is a port off the diesel engine cooling system, so plumbing it into a simple register inside the bus would provide heat. The little diesel engine surprisingly creates a lot of heat while running.
