Principle and Method of Lighter:
Principle:
1. The main components of a lighter are the firing mechanism and the gas storage tank. When the firing mechanism is activated, it generates sparks that ignite the gas in the combustion area. The firing mechanism is the most active and complex part of the lighter.
2. The fuel used in a lighter is mainly flammable gas. Early lighters used gasoline, which had an odor, but now it is rarely used. Most lighters now use butane, propane, and petroleum liquefied gas. They are pressurized and filled into a sealed gas tank, and once released into the air, they quickly vaporize and expand, making them easy to ignite. The butane used in lighters is n-butane, which is a general term for two alkanes with the same molecular formula.
Method:
The gas in the storage tank is released by mechanical parts while the firing mechanism is activated, creating sparks that ignite the gas in the combustion area. The lighter is mainly composed of a firing mechanism and a gas storage tank, and the internal gas is mostly butane, propane, and petroleum liquefied gas.
