Understanding how car engine works

As car lovers can tell and give the latest updates on new release designs, but not knowing the working in the engine. That’s not quite ok! Knowing how engines works will help to diagnose and fix problems when they occur. Having deep knowledge of how a car engine works from the early stage till date will be an interesting and surprising fact because much has happened over the year following the advancement of technology.

The early car engine works using the internal combustion process which will be further explained. In most modern cars, They are equipped with engines using electric motors and fuel, playing their perfect roles. This article will cover both methods. In my previous articles, I have discussed automobile engines. Check out!

How a car engine works

Internal combustion is a small controlled explosion that occurs in an automobile engine to generate power. This process occurs in four strokes or steps in the various chambers thousand of times in a minute. These steps include intake, compression, combustion, and exhaust. The process of powering internal combustion is called the combustion cycle.


This is the first stage in the combustion cycle. It moves the piston up and down with the motion obtained from the crankshaft. The purpose of intake is to allow fuel and air to enters the chamber for a mixture. The valve opens when the piston moves down, causing the fuel-air mixture to be released.

Compression stroke as the second stage of the combustion cycle occurs as the piston moves upwards, causing the fuel and air to mix by compressing.


This is when the explosion happens. As the piston moves upwards before moving down, a spark is produced by the spark plug, igniting the mixture and causing a small explosion. This rapidly moves the piston, helping to produce the energy needed to power the engine.


The final stage of the combustion cycle is called the exhaust, stage when the exhaust valve opens to discharge the gasses created by the explosion. This process occurs when the exhaust valve opens. The process is repeated thousand times as far as the engine is running.
