It is true that the engine with the “T” has strong explosive power and good fuel economy.

Compared with the turbocharged and naturally aspirated models with the same maximum power and maximum torque, turbocharged models are explosive and economical.

The comparison is conditional. Some netizens say that turbocharged engines are inefficient. These are misunderstandings.

There are also said that the development of turbocharging is a product of policies. When used in cars, the initial policy will certainly play a great role in promoting, and ultimately it will be able to develop, it still depends on its own really advanced technology.

Turbocharging changes the intake method, the engine control system can actively control the intake pressure, and the engine's characteristics change as well.

Why does the "T" engine have a strong explosive power and good fuel economy?

1, the engine peak torque corresponding to a wide range of speed;

The following figure shows the external characteristics of the two engines. The green line is the torque curve of the self-priming machine. The blue line is the torque curve of the supercharger. The maximum power and maximum torque of the two machines are the same, but they are at 1200rpm to 3500rpm. In the speed range, the maximum torque that the supercharger can output is greater than that of the self-priming machine. The power is certainly good.

2, turbocharger models have higher thermal efficiency

The same power output, the turbine type of basic displacement is small, 1.5T and 2.0L two engines, 2.0L engine at the same speed to maintain its own running power consumption is greater, that is, large displacement of the mechanical loss and other consumption To be large, but like its effective output, its thermal efficiency will be lower.
