    So I had the dumb idea earlier today to look up 200cc diesel engines. I previously have looked up "small diesel generators" and got nothing. I found that 200cc and under diesel engines can be had on amazon for fairly cheaply though from chinese manufacturers. Now I was looking these up to possibly set up a diy genset to run AC in the truck at night and use diesel rather than carry gasoline as well.

    Looking up some info I found that a 200a alternator should only take about 3hp to run and the link at the amazon store below has an engine that's 5hp for $386.

    Futchoy

    I figure if someone really wanted to run their ac at night with a cheap generator you could probably buy one of these, slap a 200a alternator to some homemade belt setup and have a diesel generator for less than $750. Now personally I'd want to slap a big ####ing muffler and resonator on the engine as well. Aside from that though does anyone think this would or wouldn't work?

    Yeah, it would work. Idling when necessary would be cheaper.

    If it's not liquid cooled, it might be hard to mount it where it can get enough air flow.

    Then California would require a emissions on it. The smart way today is an electric APU with a couple extra batteries to run them.

    IMHO a 200 amp alternator is overkill, I have a 12kw generator on my truck with 4cyl Kubota diesel and it has a 30 amp alternator which charges all my batteries in an hour, while running my RV style roof air

    Easy enough to add a radiator fan to blow over it.

    Go on ebay and you can buy those 3 hp air cooled Diesels all day long for under 300 bucks .
    Downsides are they are noisy, made in China and smokey when under a load .
    They are getting popular for repowering small engine gas powered equipment , I don't know about the longevity of them but so far they are getting good reviews and I'm going repower my snowblower with one this fall .
