An ordinary furnace is not an engine at all, because it does not directly cause mechanical motion. The heat or expanding gases released in a furnace can be used to drive an engine, but that is a separate component from the furnace. If a furnace is used in this manner, the engine is an external combustion engine.
Not totally, just because it is an internal combustion engine doesn't exactly mean that fossil fuels need to be burnt. The concept of the Internal Combustion engine is relatively reuseable, the major problem with it is its efficiency. As we all know a good petrol engine will probably get around 25 - 30% efficiency as in driving force. The rest is lost mostly to either friction or heat. If these problems can be rectified the Internal Combustion engine could possibly run on fossil fuels for another century (Oil depending/Government b*llshit). Yet fuel cells and other means of power are being developed so this depends on the movement of technology.
pretty much to put it simply, the purpose of the internal combustion engine is to turn potential energy in the form of petrol or diesel into mechanical energy. This is done by exploding the fuel in the combustion chamber of the engine, therefore creating heat and rapid expension of gas which drives the whole car. if you want more info just look it up on the wikipedia site, it's pretty handy and well written.
No, the steam engine is an external combustion engine because the steam is heated by heat generated by combustion outside externally through heat transfer. A spark ignition engine is an example of an internal combustion engine.
In an internal combustion engine, the provided energy is chemical energy. By means of combustion it is transformed into heat energy. This heat energy is transformed in to motion/kinetic energy in an internal combustion engine.

The diesel engine doesn't have any spark plugs, and uses heat generated during compression to ignite the fuel. The diesel however, is an internal combustion engine.
the internal combustion engine works by converting chemical energy (fuel) into heat energy. the heat energy then expands the compressed air to drive the piston down. typically a third of this heat goes straight out of the exhaust, which is why the exhaust gets hot. another third of the heat is absorbed into the engine, hence the need for a cooling system which means that only a third of the heat generated is used to drive the psiton down making the internal combustion engine only about 33% efficient. robb

Spelled as diesel, this type of internal combustion engine uses the heat of compression to ignite the air/fuel mix, and has no spark plugs.

Thermal energy is just heat. To convert it to mechanical energy you need some sort of heat engine, like an internal combustion engine or a gas turbine.
