Engines in modern cars and race cars aren't too dissimilar. They run via a process called "Internal Combustion."


Combustion, also known as burning, is the basic chemical process of releasing energy from a fuel and air mixture


In an internal combustion engine (ICE), the ignition and combustion of the fuel occurs within the engine itself. The engine then partially converts the energy from the combustion to work.


The engine consists of a fixed cylinder and a moving piston. The expanding combustion gases push the piston, which in turn rotates the crankshaft.


Ultimately, through a system of gears in the powertrain, this motion drives the vehicle’s wheels. 

In this lesson, we're going to be building our own 3D "model" engines.
