These days, everything is exquisite. Not only do people bring "T", but vehicles also have T, and more and more cars have a prominent letter T on their rear buttocks. People may get pregnant without "T". What about cars? And listen to the small editor.
Vehicle belt T generally refers to this the car is turbo charged engine, that is its engine is more equipped with turbocharger than ordinary automobile engine..
Therefore, more and more German cars are selling hot-selling mid-class cars. After five or six years of development, more and more brands have launched turbo-charged small-displacement models to cope with fuel consumption and emission standards. Turbo-charged has become the general trend, it is expected that more car companies will carry T Power on small and medium displacement models in the future.
At present, Mercedes-Benz, BMW and Audi all make Turbo Boost technology.
T-belt models have spread to hot-selling intermediate models such as American, European and independent brands. In T shape, when Turbo was rampant, not only imported cars, joint venture cars, domestic brands such as BYD, Chang'an and Great Wall also launched engines with T.
Turbocharger is actually a kind of air compressor installed on car engine intake tube to increase the intake of the engine by compressing air. General engine turbocharger mainly consists of turbine chamber and turbocharger. The air inlet of the turbine chamber is connected to the engine exhaust manifold, and the exhaust port is connected to the exhaust pipe. The air inlet of the supercharger is connected to the air filter pipe, and the exhaust port is connected to the intake manifold. The turbine and impeller are respectively installed in the turbine chamber and the supercharger, and the two are rigidly connected coaxial.
When the engine is running, the high-speed impulse of various exhaust gases from the engine exhaust manifold pushes the turbine inside the turbine to rotate, and the turbine drives the coaxial impeller to rotate, the impeller presses fresh air from the air filter pipe into the cylinder. The engine speed is faster and faster, the exhaust speed is natural, and the turbine and impeller rotate faster and faster. Accordingly, the more fresh air enters the cylinder combustion chamber, the faster it will be. More air entry means more fuel can be injected, while more fuel means more explosive power and more horsepower. In this way, more air is forced into the engine, resulting in "supercharging" in the cylinder ". The engine is just like the computer CPU being "overclocked", which can burn more fuel and output more power.
So what are the advantages of vehicle belt "T?
1: smaller engine displacement, more fuel-efficient. The turbocharger multiplies the air entering the combustion chamber of the cylinder per unit time, which will naturally make the fuel burn more fully. When the output power is the same, the fuel consumption of turbo charged engine is low. Exhaust emissions are also greatly reduced, especially the emissions per unit of carbon dioxide. In our country, small-displacement vehicles can not only save fuel costs, but also enjoy the preferential policies of car purchase with the purchase tax halved, which can be described as killing two birds with one stone.
2: The Power is greatly enhanced. More air entry means more fuel can be injected, while more fuel means more explosive power and more horsepower. The assembly of turbocharger greatly increases the intake volume of the engine, which can naturally greatly improve the output power and torque of the engine. Now 1.5T of engine power is equivalent to a 5L naturally aspirated engine.
3: high adaptability. In places with higher altitude, because the air density and pressure there are relatively low, the intake air of the engine decreases, and its performance will naturally decrease. Turbo charged engine this situation does not exist. Even if the external atmospheric pressure and density are low, there will be enough air intake. This is especially important for many cars traveling in Tibet.
Disadvantages of T models:
Customers who pursue power choose to take T, because it has stronger acceleration performance than natural aspiration.
1: the intervention of the turbine will appear very abrupt, and the sudden intervention during the urgent acceleration will make the other passengers uncomfortable.
2: Turbo models generally have high requirements on oil products, and most of them need to be filled with No. 97 fuel.
3: Turbo models need better engine oil. Generally, it is recommended to use fully synthetic engine oil for maintenance. Compared with naturally aspirated models
You will spend 20% more on maintenance every year. Do we want to buy a model with "T? I think this problem needs to be looked at separately!
If you want to buy imported or luxury brand models, the answer is of course: you want to buy models with T!
1: Mercedes-Benz
The reason is very simple. Now Mercedes-Benz has provided several regular models of 1.6T,2.0T and 3.0T, and only some models are still using 3.0 and 3.5 L engines. With T models to choose more, rich configuration, lower fuel consumption, also in terms of price, and purchase tax more advantages, then of course we have to choose with T models!
2: BMW
From 1 Series, 3 Series, 5 Series to 7 series
After the inventory of all models of X1,X3,X4,X5 and X6, we found that only BMW 730 is a 3.0-liter inline 6-cylinder naturally aspirated engine. All other models are matched with turbo charged engine. It can be described as a full lace T.
Moreover, there are many choices, 1.6T,2.0T and 3.0T respectively have high and low power, and there are 1.5T engines on the MINI that has been listed. We have to say that we have no choice but to bring "T.
3: Audi
Audi from A1,A3,A4,A5,A6,A7,A8, Q3,Q5,Q7
These models have the following engines: 1.2T,1.4T,1.8T,2.0T,3.0T
Only A6 has two 2.5-liter and 2.8-liter naturally aspirated engines in service, and the sales volume is still flat. I also want to say that basically we have no choice but to bring "T.
The answer to Audi's engine is very simple: Audi's 2.5 engine is a competitive product for the last naturally aspirated 2.5-liter engine when 525 existed that year. But BMW has already taken it offline, so Audi will be offline soon.
What if it is to buy domestic or joint venture brand models?
Then the answer is: choose according to your hobbies and requirements for vehicles.
Advantages of T models:
For the advantage of turbo charged engine, a very vivid statement is that "pony can really pull the cart". With the power of turbine, 1.8T displacement can reach the power that can only be achieved by natural suction engines above RJ45. The acceleration performance of 2.0T Volkswagen CC is even higher than that of 3.0 engine models of Volkswagen CC, while the fuel consumption is lower than that of 3.0 engine.
This is enough to prove that turbine is a good thing that can make horses run faster and eat less.
Summary:
There is no perfect product, and the model with T is not suitable for everyone. Some consumers blindly pursue taking T when they understand that the engine with T has strong power and fast acceleration, but they do not know much about the use and maintenance of such cars, and usually drive too gently, the turbine has not been in good working condition all the time, which leads to the failure of the car to exert its functions, resulting in energy and economic waste, or the lack of understanding of maintenance, the engine is damaged due to improper maintenance caused by the use of cheap oil.
So to understand your car needs is to pursue sports and passion? Or home, comfortable? Is it economical and practical? Compared with turbo models, natural suction has the greatest advantage of more economical use and purchase cost. With T is the trend of the times. Now there are many car models in the car market. Please understand your car purchase and use needs and make another choice!
