Combustion Fundamentals - Industrial Wiki - odesie

Even in a simple wood fire oxygen plays a part in combustion. A chemical reaction occurs between the oxygen of the air and the wood fuel. The nitrogen and other gases in the air do not enter into the reaction, but do carry away the gases of combustion. If a cover is put over the fire, the oxygen will be used up and the fire will go out.

How to Calculate the Stoichiometric Air-fuel Ratio

The stoichiometric air-fuel ratio is an important parameter of fuels. When designing an engine for a particular fuel, it's important to know how much air is needed to completely burn a certain amount of fuel. This article describes this ratio and presents an easy way to calculate it when the composition of a fuel is known. How air-fuel ratio can be diagnosed and monitored with the help of air

combustion - What are the differences between diesel

2019-6-9·The major difference between diesel and gasoline is the way these explosions happen. In a gasoline engine, fuel is mixed with air, compressed by pistons and ignited by sparks from spark plugs. In a diesel engine, however, the air is compressed first, and then the fuel is injected. Because air heats up when it's compressed, the fuel ignites.
