How It Works? Gasoline Car Engines
Nov 15th, 2017 | CAKNOW Tech
The purpose of a gasoline car engine is to convert gasoline into motion so that your car will move. Currently the easiest way to create motion from gasoline is to burn the gasoline inside a car engine. A gasoline car engine is an internal combustion engine -- combustion takes place internally, inside of the gasoline engine.

The ­principle behind any reciprocating internal combustion engine: If you put a tiny amount of high-energy fuel (like for instance gasoline) in a small, enclosed space and ignite it, an incredible amount of energy is released in the form of expanding gas.

Almost all cars currently use what is called a four-stroke combustion cycle to convert gasoline into motion. The four-stroke approach is also known as the Otto cycle, in honor of Nikolaus Otto, who invented it in 1867. The four-strokes are:

Intake stroke
Compression stroke
Combustion stroke
Exhaust stroke

The motion that comes out of an internal combustion engine is rotational not linear. The rotational motion is nice because we plan to turn, or rotate, the car's wheels with it.
