Engine is the name given to the equipment responsible for turning energy into motion of the vehicle in which it is installed. In the case of cars and other vehicles, the engine is called “internal combustion” because it transforms the burning of fuels in its interior in motion.
Regardless of engine type, everyone needs the same elements: air, fuel, and an explosion trigger. In Otto engines, this trigger is provided by the spark plug, which unleashes a spark inside the cylinder and generates the explosion. In diesel engines, such an explosion is generated by the compression of gases within the cylinder and the elevated temperature.
A. Internal. Most cars use that type of set up because it's more efficient, you can find more about it on this website, https://auto.howstuffworks.com/did-cars-ever-have-external-combustion-engines.htm
<span>So we wan't to know what happens during nuclear fusion where we have 12 atoms. Nuclear fusion is a nuclear process where 2 or more nuclei will form 1 or more different nuclei with a release of energy. So if we start with 12 atoms, the most likely result will be 6 atoms. </span>
