burning or oxydation
A Combustion Reaction
Another name for burning is combustion. The term combustion is more commonly used in scientific fields like chemistry and physics.
Combustion reactions are exothermic processes. When substances are burned, heat is given off. An example of this occurs in many homes during the winter. Families burn wood in their fireplaces. This releases energy in the form of heat causing the temperature of the surroundings to increase and warm up the house. In other words, burn is the answer to your questions

Combustion is another word for burning. It means a chemical reaction with an oxidising agent, usually oxygen itself, producing new substances and releasing heat.
That term is "baseline," which refers to an individual's typical or usual state of reaction, behavior, or thought process. It is used as a reference point to understand deviations from the norm.
Exothermic is the term you are looking for. This means that more energy is released from a chemical reaction than it took to initiate it. Combustion is an example of this type of reaction. The opposite of this is the endothermic reaction where a constant influx of heat is needed to initiate and continue the reaction, leading to an overall lowering of the temperature of the system if more heat is not introduced from the outside. Melting ice is an example of this.
In apperance, the term "most of the time" may apply in reference to occurrances in length of days. The term "much of the time" may apply in reference to occurrances in length of hours.
breathing is the activity animals go through to get oxygen into their circulatory system. The end result and purpose of breathing is combustion although we usually don't use that term in biology.

The term you are looking for is "knock" in relation to combustion in internal combustion engines, specifically in the context of gasoline engines.
