Analogy to Every Day Life

An analogy for combustion is an internal combustion engine in a car. The fuel injectors inject the fuel into the cylinder heads which then combines a spark to ignite the fuel which then combines with oxygen created CO2 and then it goes out of the cylinder heads out into the Cadillac converter and then burns even hotter to make sure that everything is burned off and then it goes out to the exhaust. What makes this spark also help ignite is the pistons When the fuel is injected into the cylinder heads the pistons compress the fuel and then when it ignites it shoots down and continually does this. It's also known as RPM
