Family choice car, why not recommend to choose turbocharged!

Now many vehicles are equipped with turbocharged and naturally aspirated two forms of engine for consumers to choose, many consumers in the choice of time will be hesitant, do not know which form to choose.

Self-priming engine and turbocharged engine, that is, usually people say with "T" and without "T", with "T" is a turbocharged engine, "L" is a naturally aspirated engine.

What's different about turbocharged engines

First, let's talk about how the engine works.

Where the engine power comes from, first intake, injection of oil, and then compression, do work to produce power.

How can we generate more motivation?

Very simple, on the basis of the original increase in air intake, fuel injection amount, so as to improve the power of the engine, produce more horsepower. It's easy to say, not easy to do, and turbocharging is the product of this idea.

Perhaps for some non-owner friends, or car white, almost not clear what is naturally aspirated, what is turbo?

What is natural aspiration?

Natural aspiration is a form of atmospheric pressure that pushes air into the combustion chamber without passing through any supercharger.

The popular point is that when the car is working, its intake pipe is equivalent to a vacuum tube, and the air pressure is pressed into the intake manifold by atmospheric pressure, just like the "inhale" when we usually breathe!

What is turbocharging?

Turbocharging is a technology that uses the exhaust gas produced by the operation of an internal combustion engine to drive an air compressor.

If from the structure point of view, the difference between turbocharging and self-suction is that there is an "air compressor", which increases the intake volume by compressed air, so that the turbocharging is stronger than the natural inspiratory power, which is like having a larger "lung capacity", and people with large lung capacity are of course more vigorous.

Turbocharged VS naturally aspirated

Comparison of advantages and disadvantages

Naturally aspirated engine structure is relatively simple because its development time is relatively long, so the structure is relatively perfect, and for turbocharged engine, its advantages are also more obvious, of course, the disadvantages are more prominent.

From the point of view of service life and maintenance cost, naturally aspirated engine is better, because the turbocharged work for a long time in a high temperature state, in the normal working state can be fully cooled, but after the shutdown, due to the high-speed operation of the turbine blade driven by inertia, resulting in bearing damage, in the long run will reduce the service life of the turbine.

So in theory turbocharging is not as long as a self-priming engine.

From the technical reliability point of view, the naturally aspirated engine after a long time of technical accumulation, do relatively perfect, technology has been very reliable, stable quality, oil without high requirements of turbocharging.

The structure and maintenance of self-priming is relatively simple, and it has more advantages than turbocharged engines in ride comfort, durability, stability and safety.

Turbocharged engines can be said to be not a very mature technology, with a high failure rate, such as acceleration lag, service life and other problems.

Compared with self-priming engines, turbine engines have higher requirements for maintenance, must be maintained on time, must use high-quality oil, and later maintenance costs are generally higher.

From the power point of view, the acceleration ability of the self-priming engine is relatively smooth and slow, unlike the stimulation of the turbocharged engine, turbocharged can make the car more powerful, often run at high speed is better, speed up quickly, but it is difficult to rewind freely.

A car with a self-priming engine accelerates more smoothly, the speed is slowly increased, and it is easier to control. The noise is also low.

Turbocharged & naturally aspirated

How to choose

If you drive more gently, live at home, do not want the car to have too many small problems, buy a car to want to drive for a decade or eight years, do not intend to change in a short time, and do not want to spend too much money on late maintenance, then choose natural inspiration. And live at home, choose 1.6L and 1.6L below the five-seat car, the basic power is completely enough.

But if you are not old, the car is bought by yourself to drive more. The speed, power requirements are relatively high, can not stand the slow speed, a foot accelerator, the power is still so meat of the car, and buy a car is going to open a 4 or 5 years to change, like to try more fresh models, and the late car money is more sufficient, then decisively turbocharged it. For an ordinary five-seater sedan, the 1.5T is perfectly adequate.
