The heat source may be combustion of a fuel and, since the combustion products do not mix with the working fluid(i.e. external combustion) and come into contact with the internal moving parts of the engine, a Stirling engine can run on fuels that would damage other(i.e. internal combustion) engine's internals,
such as landfill gas or Siloxane.

The heat source may be provided by the combustion of a fuel and, since the combustion products do not mix with the working fluid and hence do not come into contact with the internal parts of the engine, a Stirling engine can run on fuels that would damage other engines types' internals, such as landfill gas,
which may contain Siloxane that could deposit abrasive silicon dioxide in conventional engines.
