How does a car engine work?

Have you ever opened the hood of your car and wondered what’s going on inside? A car’s engine can look like a jumble of metal, tubes, and wires to some.
You may want to know what is going on simply out of curiosity. Or maybe you’re buying a new car, and terms like “turbocharger” and “start/stop technology” allow. What does it all mean?
In this article we will talk about the basic idea of ​​the engine
The purpose of a gasoline car engine is to convert gasoline into motion so that your car can move. Currently the easiest way to create movement from gasoline is to burn gasoline inside the engine. Therefore, a car engine is an internal combustion engine, i.e. combustion occurs internally.
There are different types of internal combustion engines. Diesel engines are one type and gas engines are another type, each with its own advantages and disadvantages.

The Principle Behind Any Internal Combustion Engine If you put a tiny amount of high-density fuel (such as gasoline) in a small enclosed space and ignite it, an incredible amount of energy is released in the form of expanding gas, this is the basis of a car engine.
Almost every car with a gasoline engine uses a four-stroke combustion cycle to convert the air-gasoline mixture into motion. The four-stroke system of the engine is also known as the Otto cycle.
Engine strokes are:

• drag stroke
• pressure stroke
• power stroke
• exhaust stroke

The piston is connected to the crankshaft by a connecting rod, and this is what happens in the four strokes:
 
the piston starts at the top, the intake valve opens, and the piston moves down to let the engine draw in enough air and gasoline to fill the cylinder. This is known as the intake stroke. Every drop of gasoline must be mixed with the air entering the engine.
The piston then moves downward to compress the fuel/air mixture. This pressure makes the explosion more powerful.
When the piston reaches the top of the stroke, the spark plug emits a spark to ignite the gasoline. The charge of gasoline in the cylinder explodes, forcing the piston down.
As soon as the piston reaches the bottom, the exhaust valve is opened and the exhaust is released from the cylinder.
Now the engine is ready for the next cycle, so it requires another charge of air and gasoline.
In an engine, the linear motion of the piston is converted into rotational motion by the crankshaft.
