How Does an Engine Work?

Cars are no longer seen as unique. Almost everyone owns one these days. However, one thing that many take for granted is the fact that the inner workings of the car, such as the engine and other components are some incredible pieces of engineering, as it showcases just how far human civilization has come to in the modern-day period. Here, we would focus more on how the engine of the vehicle functions, so you might know what to do even in the case of an emergency.


The first thing that the engine requires to operate is fuel. This can differ depending on the engine type. Fuel for engines can come in many forms such as petrol, diesel, and kerosene oil. Regardless, one thing that is common with the fuel is the fact that they all stem from crude oil. This is a type of fossil fuel that is extracted from certain parts of the world, and is highly combustible in certain circumstances. Without fuel, the engine cannot generate energy, which is required to propel the forwards or backwards. However, today, many cars require either petrol or diesel.


When the engine is fed with fuel, the crankshaft spins, allowing the pistons to move up or down. In many instances, people often mistake that the crankshaft is the one that moves the pistons. However, it is the opposite. Due to the explosions in the pistons, the crank is spun in a manner that allows the other pistons to make sure there is equal combustion. In other words, the crankshaft keeps stability and uniformity within the engine block. Although, just a simple shaft, it certainly does work overtime to make sure the engine works like normal.


Arguably, the most important part of the car, the pistons is what keeps the engine running and produces the power to make sure that the car can move forwards or backwards. Automobile engineers consider this to be the most industrious part of the car as it constantly works even when the car is in the neutral gear.

Once the fuel and air are pumped into the piston, the piston pushes the mixture up to the spark plug, which then creates a small explosion, which then drives the piston down again. The exhaust is let out through a separate valve. This happens extremely fast. In old cars, the pistons may also burn the oil in the engine as well. Therefore, you need to replace the shock piston bands to make sure the motion is smooth.


The combustion happens in split seconds. Right after that, the exhaust is driven outside the pistons to make sure they can receive new fuel mixture to repeat the next combustion phase. These are often controlled by special valves that open and close at specific periods. These exhausts are pushed out via the exhaust manifold as carbon dioxide.

Of course, there are many other parts of the engine that work during the combustion phase; however, the above-mentioned processes should suffice.
