These days, in a luxury car 4S shop in the provincial capital, people who came to see the car came one after another to ask about the model of turbocharged engine. With the increase of consumption tax, cars with a displacement of more than 3.0L have a great impact. Some turbocharged models took the opportunity to slogan that 2.4T power is even more abundant than 3.0L, attracting consumers' attention. What is a turbocharged engine in theory? ; Low fuel consumption and high displacement power? ; The biggest sign is that there is turbocharging or t at the rear of the car.

Does turbocharging technology provide consumers with another way: to enjoy the power sense of large displacement and save fuel?

Small displacement fuel consumption, large displacement power is especially suitable for high-speed driving.

Former flying man? ; Bailey described the Olympic men's 100 meter and 200 meter sprint champion Bolt as follows: It's like running with two turbocharged engines ?

Mr. Wu is also a supporter of turbocharging technology. He drives a Skoda 1.8T: As soon as the car got on the highway, the turbine started, which was very fuel-efficient. Turbocharging is a very mature technology in Germany, and the power is enough to drive. ?

The earliest turbocharging was used in sports cars or formula racing cars to boost the power of engines with limited displacement. What is the biggest feature of this technology? ; Small displacement? ; At the same time, it can save fuel and give consideration to power. According to Yu Xiaoli, director of the Vehicle Research Institute of Zhejiang University, the turbocharger uses the impulse of the exhaust gas discharged by the engine to push the turbine, so that the air is pressurized into the cylinder, which can greatly improve the power and torque of the engine without increasing the engine displacement. Theoretically, its power is 20%~30% higher than that of the same displacement engine. For example, 2.4T is more powerful than 3.0L displacement.

According to Lan Xufeng, sales manager of Yuan Rui Volvo, many consumers have reflected this technology. Small displacement fuel consumption, large displacement driving experience. ? Volvo's turbocharged engine can be started at 1500 rpm. When driving, consumers only need to follow their daily driving habits. You don't have to think so exquisitely about a turbocharged car, but it's not difficult to deal with. ?

Mr. Liu, an automobile expert, said that in theory, turbocharged engines will increase power and reduce heat loss. But whether it can reach the theoretical value is still related to the technology of the manufacturer. If the manufacturer can set the price reasonably and add the new consumption tax policy, the turbocharged model will usher in the spring of development.

Waiting to see the school

2.4T has 3.0L motivation, and its psychological effect is only in the urban area, which has little effect.

The power of 2.4t reaches 3.0L The so-called fuel saving depends on what you compare with. The fuel consumption of 2.4t is higher than that of 2.4L, but it is definitely more fuel-efficient than that of 3.0L This is equivalent to one more node and more fault points. ? Zhou, an automobile expert, admits that turbocharging is of little significance. It's just a selling point for businesses. ?

Mr. Dong, a technician who has been engaged in automobile maintenance for many years, said that the maintenance requirements of turbocharged engines are higher and the maintenance costs will increase. In addition, steam turbines often run at extremely high speed, and losses are inevitable. Some consumers have bought a turbocharged engine model and often come to change the impeller.

According to the engine designer of a joint venture brand, German cars mainly use turbocharging, and the power output lags behind. If you accelerate suddenly, you will suddenly feel that you can't keep up with the speed. High-speed operation can reflect the advantages of turbocharging. There is still a difference in driving experience between turbocharged cars and large-displacement cars. In actual driving, the acceleration of 2.4t is definitely not as good as that of 3.0L, and the power of 2.4t will only appear after the waiting period. A Subaru impreza owner said that his car would not start until it was turbocharged to 3500 rpm. In general, the gear shift in cities is between 2000 and 3000 rpm, and the fifth gear can reach 3500 rpm, and the speed is120 km/h. There are many traffic lights in large and medium-sized cities, and the turbocharging can't be started. 2.4T can only be used as 2.4L, and the power of 3.0L is only psychological. If you only drive in urban areas, you should consider whether it is necessary to choose turbocharging.

Turbocharging is expensive? There are tricks to use!

Mr. Dong, an automobile maintenance technician, suggested that consumers should choose a high-quality and durable turbocharged engine to avoid worries. Teacher Dong also gave some tips on using turbocharged engines:

1. After starting, don't slam on the accelerator, but idle for three minutes to fully lubricate the turbocharger;

2. After the engine runs at high speed for a long time, it cannot be turned off immediately;

3. Choose oil. In addition to the engine oil specified by the original factory, you can also choose high-quality lubricants such as synthetic engine oil and semi-synthetic engine oil.

4. Keep the oil and filter clean to prevent impurities from entering;

5. Always check whether the sealing ring of turbocharger is sealed;

6. Regularly check whether the turbocharger has increased vibration or abnormal noise to prevent the lubricating oil pipe from leaking.
