What type of engine would work in the world of TLD?

[Willy Pete]

I've seen a number of folks on the Wishlist forum asking for different vehicles and whatnot in TLD, but it's always snow mobiles or automobiles and as these both use traditional gasoline or diesel engines that require things like timing, electrical starters and motors and the like they wouldn't work in the quiet apocalypse. During an Aurora event you'd have constant power provided to your spark plugs which wouldn't allow the engine to run and the power required to power the starter would probably not be available with the Aurora alone.

But not every type of engine requires electricity to function. 19th Century steam engines, for example, would work just fine as they rely on burning coal to heat up water to drive a piston. No electronics required. 

My question for all of you folks is: what other types of motors/engines would work (if there even are any)?

Stirling engines and anything with a mainspring (like a clock), those motors would still work.  But in addition to steam engines, certain older diesel motors don't require electrical components to work.  You have to pre-heat the fuel and manually start the engine somehow, but once it's going the it can run without electricity.  Fuel injection is handled mechanically, and ignition is done via compression. For some place like Great Bear, an old diesel truck from the 70's is the most feasible way of reasonably modern travel after the Event.  The lights would probably be fried, but if you could get the engine started, you'd be good to go.

An 8-dogpower engine - i.e. dog sled and team.

Seriously, I really like that there are no engines that can run in TLD.  I like the quiet with no industrial or manmade sounds going on.
