Defining the Internal Combustion Engine
The internal combustion engine (ICE) is a heat engine that generates mechanical energy through the combustion of fuel and air within a confined space. This process occurs in one or more cylinders, where the resulting gas expansion powers pistons, ultimately converting thermal energy into kinetic energy.
The ICE operates on the principle of converting the chemical energy of fuels—such as gasoline or diesel—into mechanical energy via a controlled explosion or combustion. This energy transformation is pivotal to its function and distinguishes it from other types of engines, such as external combustion engines or electric motors.
Fuels combust within the engine cylinder, creating high-pressure gas that drives the pistons. This motion is subsequently transferred to the crankshaft, which powers the vehicle’s drivetrain. Hence, the birth of the internal combustion engine has significantly influenced automotive engineering and transportation as a whole.
