The Difference Between Naturally Aspirated Engine and Turbo-Boosted Engine

A Quick Look at the Difference Between Naturally Aspirated and Turbocharged  Engines - AutoInfluence

Have you thought lately to sell your car in Dubai and get a supercharged one to enjoy some extra adrenaline? If yes, we will help you today understand the whole matter before taking the decision.

Let’s briefly talk about what atmospheric engines and supercharged engines are.

First of all, these terms imply air intake. An atmospheric engine, or a naturally aspirated engine, uses the movement of the pistons to breathe the outside air ( it depends on the atmospheric pressure, thus called an atmospheric engine). 

The Power

A turbo engine has more power coming directly from the combustion in the cylinders. With a turbo engine, you can squeeze more air into the cylinders than without. And as we manage to send more oxidizer (air, and especially the small portion of the oxygen in it) we can send more fuel, thus having more energy to burn for a cycle. The term “supercharging” is very telling: we charge the engine with as much air and fuel as possible.

The air intake of a naturally aspirated engine depends on the revs since that’s when it gets the most air and fuel. A turbo engine can have a lot of air and fuel from low revs since the turbo stuffs the cylinders with “artificial” air (added to that naturally sucked in by the movement of the cylinders). By bringing more oxidizers, more fuel is sent during these low speeds, which then brings a surplus of energy.

The Consumption

At low speeds, a turbo engine operates like an atmospheric one since it will not use the turbo (exhaust gases too weak to animate it).

And this is precisely where turbo engines deceive people, they do not consume much at low revs compared to atmospherics since on average they are smaller (smaller = less consumption)

Nevertheless, when the power is exploited, the turbo engages and then begins to pour a flow of air into the engine. 

Unfortunately, the more air there is, the more you compensate by sending fuel, which then explodes consumption.

Car Inertia

Turbo engines have greater inertia which reduces the pleasure and the feeling of sportiness. The turbines influence the incoming (intake) and outgoing (exhaust) airflows, therefore, causing a kind of inertia concerning the speed of acceleration and deceleration.

But it’s not just turbo-charged cars that have this effect; regular vehicles with exhaust gas recirculation systems achieve similar results by adding a turbine into the EGR system. The engine will take longer to accelerate, but it will also run smoother at higher speeds.

Car Response

Another consequence of using a turbo-boosted engine is the slower response.

The response of the engine is less dazzling with turbo. Car Response will depend on many factors including how fast you accelerate, your engine size, type of tire, road surface, speed limit, load (if any), and weather conditions. The best car response depends on what you want from your vehicle. Some people prefer more aggressive acceleration than others. If you want more power at lower speeds then it might be worth considering sports cars which typically have better performance at higher revs and therefore better acceleration but require more fuel at lower speeds.

Car Reliability

The more parts there are in an engine, the greater the risk of breakdowns. The turbo engine has both a sensitive part (fragile fins and bearing that must be lubricated) and a part that suffers damage and enormous constraints (hundreds of thousands of revs per minute). So, if you don’t mind the repetitive breakdowns, you can enjoy the power of a turbo-boosted engine.

In the end, it comes down to what you prefer. If you want to experience the power of the turbo but don’t want to pay a high price then regret it, used car dealers in Dubai are full of turbo-boosted engines to pick from and find out if it’s the perfect ride for you.
