The domestic automobile industry started late, and people know less about cars. In the early days, many people only paid attention to the price and appearance of the vehicle when buying a car, and did not pay much attention to the power configuration and performance of the car. With the continuous popularization of cars, people's understanding of cars is also getting deeper and deeper, and everyone no longer only looks at the appearance when buying a car, but also begins to pay attention to the performance of its vehicle.
The three most important parts of the fuel car are the engine, gearbox and chassis, and if a car wants to obtain abundant power performance, it needs to have a strong heart, so the importance of the engine is self-evident. At present, there are two main types of engines that are popular, one is a turbocharged engine and the other is a naturally aspirated engine. What is the difference between these two engines, and which one is better when buying a car?
The performance gap between the two engines is very large, and the naturally aspirated engine appeared relatively early, the technology is mature, and it is not easy to have problems. Japanese cars are very fond of using naturally aspirated engines, and some Toyota, Nissan, and Honda cars are equipped with naturally aspirated engines.
Advantages of naturally aspirated engines
The idling state is quiet and smooth, and when the car first starts, the noise of the engine and the smoothness of the operation are very good. Moreover, the naturally aspirated engine is very in place in terms of power control, and the output of the force when controlling the throttle can be kept unchanged at a certain force, so that the acceleration of the vehicle is kept in a relatively smooth and uniform state.
High fuel economy, can meet the needs of most car owners. Naturally aspirated engines do not have turbochargers, and in the case of the same displacement, the fuel consumption of naturally aspirated engines is 1 to 2 liters lower than that of turbocharged engines. Many people think that Japanese cars save fuel, not only because they are technologically mature, but also because many cars use naturally aspirated engines, and also in the idle state, the naturally aspirated engine has a lower injection volume than a turbocharged engine.
Advantages of turbocharged engines
The turbocharged engine has one more turbocharger than the naturally aspirated engine, which can increase the intake of the engine and allow the vehicle to obtain a greater output torque. In the same displacement, the power performance of the turbocharged engine is stronger than that of the naturally aspirated engine.
However, the disadvantages of the turbo engine are also obvious, in the idle state, the turbo engine jitter is more obvious, and the fuel consumption is high. According to the actual driving experience of the owner, only after the engine speed reaches 3000, its actual performance will be stronger than the naturally aspirated engine.
Therefore, many people feel that if buying a car is just a daily urban transportation, it is enough to choose a naturally aspirated engine. Urban roads are often congested, and the amount of fuel injected when the vehicle starts is the highest. The fuel consumption of naturally aspirated engines in the idle state is relatively low, and the choice of naturally aspirated engines is also a more economical and fuel-efficient decision.
If you often have to run at high speed, the advantages of naturally aspirated engines are gone, and in the state of high-speed driving, the 2.0-liter naturally aspirated engine is not as good as a 1.5T turbocharged engine. Because the explosive power of the naturally aspirated engine is relatively poor, when accelerating overtaking, the naturally aspirated engine cannot provide itself with greater power output.
Many car owners have said that the gap between the two engines when driving at high speed is very obvious, it is simply a day and a place. However, the two engines are required to have their own advantages and disadvantages, and there is no absolute conclusion, because under different operating conditions, their performance is completely different.
