Introduction
Car engine is amazing machine that convert the heat energy to mechanical energy to let the car move. As we know the modern car engine is works in the internal combustion so it is call internal combustion engines. But for the older technology, they used External Combustion Engines. It is far lower efficiency than internal combustion engines. The steam engine in old-style trains and steam boats are the best example of ECE (External Combustion Engines). The most of fuel that used in ECE is coal. The coal is burned to create the steam, and the high pressure of steam compressed and it create a motion in the engine. As we known gasoline and diesel are the basic fuel for Internal Combustion Engine. The gasoline and diesel are the type of gases that made from petroleum. The combustion of gasoline and diesel are mean that the gasoline or diesel react with the oxygen to create water and carbon dioxide gas. Gasoline/petrol is a mixture of few organic compounds, but the main compound of the Gasoline/petrol is the octane C8H18. So the simple chemical equation is 2C8H18 + 25O2 ( 16CO2 + 18H2O. Diesel is also a mixture of few hydrocarbon compounds. Diesel goes from C10H20 to C15H28 but the main compound of the diesel is C12H23. So the chemical equation is 4C12H23 + 71O2 ( 48CO2 + 46H2O. There are still possible for incomplete combustion of gasoline/petrol and diesel. Both incomplete reactions will produce the harmful carbon monoxide gas which can affect our wealth and oxygen gas. The incomplete combustion is performed because of not enough amount of oxygen gas. For the incomplete combustion of petrol, C8H18 + 17/2O2 ( 8CO + 9H2O. For the incomplete combustion of diesel, 2C12H23 + 27/2O2 ( 24CO + 23H2O. The coal is rather a mixture hydrocarbon compound, so there is no chemical formula for
