Small displacement and strong power drive turbo sales

With the trend of energy conservation and emissions reduction, small displacement turbocharged engine gradually get highly regarded by large car manufacturers. Recently, Beetles releases a new generation of 1.2 TSI and 1.4 TSI models; Fiat also carry a 1.4 T - JET turbocharged engine. What consumers’ views on is turbo model cars? According to a online survey on consumers’ taste on turbos, about 60% auto owners participate in the survey among 50,000 valid questionnaires.

How about the popularity of turbo cars?

Generally speaking, if you find Turbo or T marks in the back of a car, namely, it has a turbocharged engine, such as AUDIA6 1.8T, PASSAT 1.8T, BORA 1.8T and so on. Let’s take a look at the turbo engine working principle. It rely on turbocharger to increase the engine air inflow, turbocharger (Turbo) is actually an air compressor. It is the use of the waste gas emitted from engines as power to promote turbine wheels in the turbo turbine (in exhaust passage), and turbine wheels drive the coaxial compressor impeller inside the inlet, which compress fresh air brought by  air filter pipe and then push the air into the cylinder. When the engine rotates faster, exhaust emission speed and turbine wheel speed will synchronous speed up. Correspondingly, the compressed air will be increasing at the same time as well as engine air inflow, which can increase the output power of the engine.

 In normal work conditions, there are some at air pressure at both ends of the turbocharger compressor wheels, like Garrett compressor wheels, so the engine will not flow from low pressure area to high pressure areas. What’s more, seal rings have the function of sealing gas oil. Even so, turbocharger oil leakage is also likely to happen without proper operation. Here are some common causes and preventive measures for turbochargers.

So how much consumers know about turbo engines? The results of the survey show that most respondents have a certain understanding on a car turbocharger’s working principle. What’s more, most car owner respondents have the intention to buy such model cars.

Now, an engine can be divided into naturally aspirated and charged types,of which charged types have supercharged, turbocharged and the latest gas wave booster. Naturally aspirated type in the form of atmosphere air pressure into combustion chamber without any boost.

From the survey results, the majority of respondents have the intention to buy "turbocharged models", but car owners cars prefer "naturally aspirated" models while those who have no cars have more interest in turbocharger engine cars.
