Reflection on engine lab experiment

Though this demonstration, l learn the basic knowledge on how to provide the energy to fly the airplane, it is complicated to operate the engine, hence it requires specific skills and careful planning.
Below is the process of running the engine that i have learned in the lab.  
The engine is started by rotating the compressor with the starter, the outside air enter to the engine. At the burner, the ignition is igniting the mixture of fuel (in this case, the kerosene) and air in the combustion chamber with the igniters which acts as the automobile spark plugs. Thus, when the engine has started and its compressor is rotating at sufficient speed, both the starter and igniter are turned off. Despite having the silencer installed in the engine, we still need to wear the ear protection. The temperature inside the internal engine can reach up to 400-600 degree celcius during operation. While, the external temperature will be lower than the internal at about 150 degree celcius.
