Choose a turbocharged or naturally aspirated engine to buy a car? Old driver: Just stop the car once ~

When buying a car, there is an enduring topic: choose a naturally aspirated engine or a turbocharged engine? Just now ... at that time, the editorial department was still arguing about V8 self-priming or 6.6T twin turbocharging. what do you think?

Before we get entangled, let's take a look at the difference between the two engines. Which is better, suction or turbine?

Power: What are the advantages of turbocharged and naturally aspirated?

We narrowed it down to turbocharged engines and self-priming engines for ordinary family cars. After all, not many people really have the money to worry about V8 self-priming or 6.6T twin turbocharging.

If you don't speak with data, you are playing hooligans. Let's look at the next set of comparison charts:

Would it be more intuitive to look at it this way? Two power versions of the same model, or two models of the same level, the power of turbocharged engine will be better than that of naturally aspirated engine. 1.5T? The actual power even exceeds that of the 2.0L self-priming engine.

However, the naturally aspirated engine will be more stable and the power output will be more linear, so the maximum torque burst is usually in the region with higher speed. For example, Nissan Teana 2.0L can't output the maximum torque before 4400rpm, and the acceleration of self-breathing cars will be more stable and uniform. It will be better in terms of ride comfort.

Relatively speaking, turbocharging has a good performance at low speed, and the peak torque of 1.5T Focus can last from 1750 rpm to 4500 rpm. When the power level is close, its linear acceleration performance is often better, which is more suitable for friends who pursue speed and passion.

Fuel consumption: Who is more fuel efficient?

Regarding fuel consumption, everyone should know that the biggest advantage of small-displacement turbocharging is fuel saving. Indeed, if it is in normal road conditions and high-speed driving, turbocharging is more fuel-efficient than natural inhalation. On the premise of the same output power, the turbocharged engine is lighter and smaller, which makes the whole vehicle lighter and reduces natural fuel consumption. Furthermore, why promote small-displacement turbocharging now? Emissions are one reason. Under the same power, the exhaust emission of turbocharged engine can be reduced by 18% to 35%, and the fuel consumption can also be reduced by about 10%.

However, don't forget that this is under normal road conditions. Traffic jams in the morning and evening rush hours are not like this. When turbocharging starts, the power is not enough, and the driver needs to step on the accelerator deeply. At this time, the turbine intervened, but it didn't take long to stop. If you stop and go like this, it will consume oil. On the other hand, naturally aspirated engine accelerates smoothly, and its comfort and fuel consumption are better. Therefore, some "old drivers" like to say: the difference between natural inhalation and turbocharging, you will know once you block the car!

At high altitude, which is better, turbocharging or natural inhalation?

The answer is turbocharging!

This is not nonsense, nor is it a "cloud evaluation", but the answer I really brought back after the test drive in Daocheng Aden at an altitude of 4500+.

At high altitude, not only people will have altitude sickness, but also cars will have altitude sickness. According to the Basic Research on the Application of Internal Combustion Engine Working Process in Plateau Environment, due to the drop of atmospheric pressure, at an altitude of 500 meters, the power of naturally aspirated engine began to decrease by about 3%, while that of turbocharged engine only decreased by 0.6%.

Therefore, when the altitude rises to 5000m, the power of naturally aspirated engine will decrease by 5 1.8%, while the turbocharging will only decrease by 35%.

In addition, the history of turbocharging can also verify this point. Turbocharging technology actually originated from the aviation technology of World War II fighters, and the purpose of this technology is also to solve the problem of fighter performance degradation at an altitude of 10,000 meters.

Who costs less to buy a car and maintain it later?

Theoretically speaking, natural inhalation is more resistant to opening and its life is usually longer than that of turbocharging. Moreover, naturally aspirated engine is the most traditional engine with mature technology, low production cost and convenient maintenance. You can see that the version of the self-priming engine of the same model is generally lower than that of the turbocharged engine.

Turbocharging has higher requirements for oil products, spark plugs and engine oil, and higher maintenance costs. Basically, after 50,000 kilometers, the self-priming engine can save one or two thousand yuan compared with the turbocharged engine.

However, you may often hear from the "old drivers" around you that turbocharging has a high failure rate, is unreliable and even burns oil. These are all things of the past, and now some new and reliable big brand turbocharged engines have no worries in this respect, so don't entangle this matter.

Buy a naturally aspirated engine or a turbocharged engine?

This topic has been debated in the automobile circle and the fan circle.

This needs to be decided according to your car demand. Take LaVida, which ranks first in car sales, for example, its version of 1.5L self-priming engine is 1 13 horsepower, 1.4T turbocharged engine can explode 150 horsepower.

However, after measurement, a 90-horsepower general family car can meet the needs of daily transportation; But if you want to overtake safely at high speed, you need 150 horsepower.

Combined with most of the differences mentioned above, the answer is obvious. If you have more private cars, like a stronger driving desire, and occasionally run long distances and high speeds, turbocharged engines are more suitable for you. Small displacement, low fuel consumption and stronger power mean saving money for you. As for the problem of acceleration lag that online car fans often say, in fact, 99% ordinary car owners simply don't feel it.

If you have many families, pursue stability and comfort, and often experience stop-and-go road conditions in the morning and evening rush hours, natural inhalation is more advantageous and its subsequent maintenance cost is lower.

In short, there is no best, only the one that suits you best. Finally, the question is, is your car a turbocharged engine or a naturally aspirated engine? Which engine do you recommend more? Leave a message to discuss it ~
