Kerosine = Jet-A. It most definitely is very different from Avgas 100LL.
The only way (in current aviation practice) to burn Jet-A is in a turbine or in a piston engine that is based on the Diesel design (high compression ratio, direct injection, self ignition). And incidentally, the Thielert/Centurion engine I talked about earlier can use both Jet-A and regular car diesel fuel. Don't know about the SMA engine though.
