Internal-combustion engine burns fuel within a closed chamber. The potential enrgy of the chemical bonds in the reactant gases is converted to kintetic enrgy of the particle products of the reaction. A engine that would be like this is an 3.0 liter V6.

This engine burns fuel within a closed chamber. This internal-combustion engine uses the potential engergy of the bonds (chemical bonds) in the reactant gases to convert it to kinetic energy. An example of this type of engine is a 3 liter V6. THE END

The gas fumes mixed with air enter the cylinder and are lit by the spark plug. Then the combustion pushes the piston up turning a shaft, and when it comes down more fuel and air is ignited again. Any gasoline engine is an example of this.

Internal-combustion engines burn fuel within a closed chamber (the cylinder). The potential energy of the chemical bonds in teh reactant gases is converted to kinetic energy of the particle products of the reaction. These gaseous products push against a piston and thus do work on the environment. A gasoline engine is one type of internal-combustin engine.

Work is done by the piston as it adiabatically compresses the fuel and air mixture in the cylinder. The hot, high pressure gases from the combustion reaction expand in colume, oushing the piston and turning the crankshaft. Then once all of the work is done bu the piston some energy is transferred as heat through the walls of the cylinder. Then it repeats all over again.

A 4.0 V8 engine would be like that
