What's a paraffin engine?

Another name for an engine that runs on what was commony in the UK
called TVO which stood for Tractor Vapourising Oil.

Stopped being manufactured in the early 70's when most tractors that
used it had been replaced by diesel engine ones.

You started them on petrol and when hot enough vapourise it switched
to TVO .
My Dads Fordson had two tanks and once you got the thing going you let
it run all day, if you stopped it then it would cool enough to stop
efficient vapourising but still be too hot to start easily on petrol.
With just a crank handle to start it could be a right pain.

Owners who exhibit/play with old TVO tractors often brew a substitute
from heating oil and some petrol.
