Before the 1960s, the large-displacement V8 engine was the mainstream in the world. After that, the V6 engine gradually emerged. However, if you want to buy an SUV or a car today, you may find that it is equipped with a 2.0T turbine. Supercharged engine.
Unless you want to choose a smaller model or a million luxury car, it is difficult to avoid the 2.0-liter turbocharged engine option. Currently there are more than 200 cars in the country to provide 2.0T engine, and this number is still continuing increase.
From the Landwind X5 with a price of around 100,000 to the 1.175 million Range Rover New Energy, the model with a 2.0T engine is very broad. In terms of tuning, the power range of the 2.0T engine is also very wide. In terms of the Mercedes-Benz M274 engine, tuning The lowest C200 power is only 184 horses, and the highest adjusted A45 can reach 381 exaggeration.
Why do most cars use the 2.0T engine?
According to Mike O'Brien, vice president of modern automotive product planning, the 2.0T engine is just as good as a conventional V6 engine. The engine's heat dissipation and heat resistance determine the turbocharger level, 'O'Brien' Said, 'Although the cooling effect of direct injection technology allows us to increase the engine's compression ratio and boost level, there are still limitations, and most automotive manufacturers encounter the same situation.' Hyundai Motor Company says its current engine The maximum boost pressure is 1.17 bar.
Lexus’ Global Strategy Network Manager Paul Williams said: 'Lexus chose the 2.0T engine to value its performance, balance between weight and engine efficiency. A 2.0-liter in-line four-cylinder turbocharged engine with a capacity of 0.5 liters per cylinder We have found that the relationship between engine power and weight using this design is the most balanced.
In recent years, many luxury sedans and SUVs have changed their previous large-capacity naturally aspirated engines to 2.0T turbocharged engines. Although the book data has decreased, the actual power level has increased.
For example, the Audi Q7 with a 4.2-liter naturally aspirated engine has a 350-hp and 100-km speed of 7.4s, while the 2018 Audi Q740TFSI is equipped with a 2.0T turbocharged engine with 252 horsepower, but the 100-km acceleration has reached 7.1s. Because the peak torque output speed range of the turbocharged engine is wider (1600rpm-4500rpm), and the naturally aspirated engine's peak torque output speed is mostly only one point (3500rpm), so the turbocharged engine can be more Output maximum power.
Automobile manufacturers use 2.0T turbocharged engines instead of large-displacement naturally aspirated engines, largely to improve fuel economy to meet customer needs and stricter government regulations. Fewer cylinders means less The components, on the one hand, will reduce the frictional losses of the energy inside the engine, and on the other hand will reduce the weight of the engine. Therefore, in theory, the 2.0T turbocharged engine will burn less fuel than the large displacement naturally aspirated engine.
Conclusion
The 2.0T engine is popular because it can perfectly replace the previous large-displacement naturally aspirated engine. Smaller engines can bring more space in the vehicle and more storage space. Although the smaller displacement of high power The engine will certainly appear, but for a long time in the future, the 2.0T turbocharged engine is still the mainstream.
Do you think 2.0T is gold displacement?
