Naturally aspirated or turbocharged engine? Which car engine to choose. What are the benefits of a naturally aspirated gasoline engine?

The choice of drive is a key issue for every motorist. There are many different types of motors to choose from. Interestingly, some of the functions used in them, such as account replenishment, were rare a few decades ago. It was an engine solution designed for luxury or sports cars, and naturally aspirated engines dominated everywhere. It showed efficient operation, although it did not allow charging, and its operating costs and fuel consumption were low.

Now the proportions have changed. Dealers are moving away from cars with naturally aspirated petrol engines due to low torque, high emissions and a greater chance of breakdowns. The most popular turbocharged, diesel and turbocharged models among motorists will dominate. It turns out, however, that there are still quite a few manufacturers who appreciate naturally aspirated engines and do not want to give them up at all. A positive attitude towards these units is represented by quite a few drivers. When considering choosing a car, you can consider those with a naturally aspirated engine. Such units will be beneficial if you prefer low-dynamic driving on local roads or in the city.

Naturally aspirated engine - operation

A naturally aspirated engine is also called a naturally aspirated engine. This engine is not turbocharged. When the combustion chamber is filled, air from the environment will be sucked in, which is the result of a decrease in pressure inside the engine. This process will create a fuel-air mixture. For comparison, in a gas turbine engine, air is drawn in by a compressor. Due to this, the gas entering the combustion chamber is under greater pressure than outside. This is what increases the power of the engine. 

Despite the increase in performance, there can be serious disadvantages, for example in the form of engine overload. This can be seen in the example of a small engine. In this context, the 2.0 naturally aspirated engine has clear advantages. This can be seen in the example of the 1.4 power unit, which has a naturally aspirated engine and a power of 95 hp. In the case of a turbocharged engine, the power increase will reach as much as 160 hp. 

Such a sharp jump will cause severe engine operating conditions, as well as significantly higher temperatures. This will affect the life of the device. Statistics show that a naturally aspirated engine will be able to drive without straight up up to 500 km. In the case of a turbocharged engine, a major overhaul may be needed after 200 km. km. Most often, the head cracks, the pistons burn out, or the timing chain is pulled. Before buying, you should find out what naturally aspirated engines are and in which cars they are offered.

What can be valued for naturally aspirated engines?

If you're an experienced driver, you'll probably remember the days when turbocharged engines dominated the market. Manufacturers have indicated that they are more practical than even the best naturally aspirated internal combustion engines, due to their economy and environmental friendliness. This had to be confirmed by research in the laboratory. However, practice quickly confirmed this theory. Motors with a turbine have more dynamics, but at high speeds, gasoline will be consumed much more than when it comes to cars with naturally aspirated engines. 

This is the main advantage of this type of drives. You will appreciate them, especially if an economical and fairly quiet ride is important to you. A naturally aspirated unit would be a much better choice if you are a driver who mainly drives on city roads that are very often congested. Then you won't even be able to use the turbo.

Naturally aspirated petrol engine - service life

When it comes to naturally aspirated engines in new cars or used cars, you will definitely care about their lifespan. We need to focus on prevention. Remember that although such units are more durable than turbocharged ones, regular visits to the mechanic will be necessary. Driving style is also important. Pay attention not to drive aggressively because small engines are very sensitive to this, regardless of whether they have indirect or indirect injection.

You can't drive too economically either. Dynamic driving leads to overloads and dangerous overheating of the engine. In turn, the environmental approach will load the crank-piston system. This, in turn, can lead to the fact that the bearing shells will have to be changed much earlier. Also remember that whether you have a naturally aspirated or turbocharged engine, the powertrain will be in good shape for long distances.

When choosing an engine, think carefully about what you will use the car for. This will make it easier for you to determine which type of drive will be the most efficient and cost effective solution.
