The heat generated by a glow plug gets directed to the cylinders. The glow plug is a heating device mostly used to help start diesel engines. It is pencil shaped.
Most diesel engines will have a 'glow' plug that gives of enough heat to help get the engine started. The heat generated from the first few revolutions together with the compression from the piston is enough to ensure the engine keeps running. Some modern diesel engines no longer require a glow plug.

The glow plus starter provides the original heat source -this is done with heat not a spark- to start the engine. After your car is on idle you could remove the glow plug starter and your car would continue running (try it if you want, ads that little bit of speed from less weight).
