The project for combustion ignition is used through the Fire Piston. Originally, it was made for kindling fires, used mainly in South East Asia and the Pacific Islands for many years (ancient times; BC). It's earliest recorded use in the West was from 1755 in a book from a Roman author, Father Boscovich in De Letteraria Expeditione per Pontifican Ditionem (The Clever Mechanism). In it, he claimed it was invented in 1745 by Abbe Augustin Ruffo. It reached New York through an article in 1876 by Professor Govi, ultimately making all the claims, so it's origin is still questioned and widely debated today.
It is also referred to as a fire syringe or a slam rod fire starter, as it's appearance is a rod with a hollow cylinder (closed on one side and open on the other) inside that fits a pump. When the pump enters the rod with enough force, pressure and temperature builds with the rapid compression. If it is pumped too slowly, then the heat will dissipate and return to equilibrium. It is very similar to how a typical engine works. In fact, it is said to have inspired Rudolph Diesel, the inventor of the Diesel engine for automobiles.
The scientific principle of this project deals mainly with thermodynamics and the adiabatic process. Thermodynamics is a branch of physics that involves the use of heat and temperature with their relation to energy and work. It describes the bulk behavior of a body, not microscopic and is commonly used within the field of engineering. It was created by French physicist Nicolas Leonard Sadi Carnot in 1824 to improve the efficiency of steam engines used in the Napoleonic Wars. Through thermodynamics comes the adiabatic process, which is the process between the transfer of heat or matter between a system and its surroundings. Essentially, this explains the fire ignition within the rod, through the application of force, increasing the energy and transferring the heat to yield fire.
