"How A Car Engine Works" to explain the mechanism of the engine by animation

Well-made tools and machines are useful without knowing the mechanism, but sometimes they are touched by taking their eyes off of their mechanisms. There is a site which introduces the mechanism of "engine" of automobile which is one of such machines with infographic including animation, and it is interesting content even by just looking at it.

How A Car Engine Works (animated infographic)

This site was created by creator / designer Jacob O'Neal. I saw it in my teens.InfographicIt is said that he was fascinated by the world and started designing.


Speaking of infographics, it is often a still image packed with a lot of information, but what O'Neill made is characterized by animation. In this work, general4 stroke engineWe divide the inside of the group into several groups and introduce the mechanism. Although it is the contents described about a very basic engine mechanism, it is made easy to understand by combining with animation.

◆ 4 Stroke Engine Basics
Inspiration: First, mix with air and fuel and suck ... ...


compression: Compress in cylinder (cylinder).


Combustion (Explosion): If you ignite the compressed air and fuel with a spark plug, a small explosion will occur in the cylinder and push the piston down. It converts this pushing down force to the force that rotates the shaft (crankshaft) and creates the force to run the car.


exhaust: Drive dirty air after burning out of the cylinder and prepare for new clean air.


By repeating these four processes at tremendous speed, the engine creates power.

◆ Actual Engine Structure
Arranging four cylinders and piston combinations vertically will be a commonly used car engine in general. Below that are shown "V type 2 cylinder", "horizontally opposed 4 cylinder", "V type 6 cylinder", "V type 8 cylinder" from the left as an example of the piston layout.


In addition, this layout has some degrees of freedom, Honda's racing bike "RC 211 V"Mounted on"V type 5 cylinderRare layout and ... ....


It is said that it is "the fastest car on the market"Bugatti VeyronIt is mounted onW type 16 cylinderThere are also.


◆ Function of each system
As written in "The engine is not driven by coffee and the deadline like human beings", the engine works by combining various systems.

Fuel and air supply. The amount of air required to consume about 75 liters of gasoline seems to be equivalent to three 25 - meter pools.


Oil supply and cooling system. A car running on a highway emits heat equivalent to two houses, so a cooling system is essential.


Electrical system and exhaust system. You can see it when you see the animation, but the cylinders are not ignited in order from the end. In this figure, the ignition is done in the order of "1 → 3 → 4 → 2". This is mainly to reduce the vibration of the engine, improve the ride comfort and extend the life of the engine.


Finally, the hybrid system is also described.
