To save fuel Turbocharger In Car Brands Audi, BMW and VW
Lately more and more manufacturers use turbochargers to save fuel, reduce emissions exhaust, while keeping the car remains nimble (steady acceleration). Anyway, now many small engines, 1.0-liter, turbocharged.
Reality - according to Consumer Reports (CR) - not all small engine with a turbo, efficient and agile than the larger capacity without the turbo.
CR is not alone! According to the BBC Auto, on Internet forums also appears frequently complaints from consumers to producers. They were disappointed, fuel consumption turbo cars they buy are not in line with expectations.
Non-turbo
Ford returned the spotlight! Understandable, because the incentive to introduce EcoBoost engine 1,000 cc, 3-cylinder turbo equipped. CR reports, the Ford Fusion 2013 with a 1.6 liter 4 cylinder, turbocharged, acceleration of 0-96 km / h slower. Fuel consumption is also not very efficient compared with the larger capacity engine non-turbo.
CR proving the Chevrolet Cruze sedan. Incidentally this model provides two options, and with the engine without a turbocharger. Both produce the same power. Conclusions CR, Cruze 1.8-liter engine, 0-96 kph acceleration almost as quick with a 1.4 liter turbo engine. So is the fuel consumption.
The problem is, to get the turbo engine, consumers must pay higher prices. Likewise with care! While the engine without the turbo, in addition to simple and inexpensive, maintenance is easier.
Reality
"Turbochargers pump more air into the engine. The amount of fuel that is burned to produce more so that maximum power as needed. For example, to make acceleration passing. When it does not require power, the engine burns less fuel, "said Winter, editor in chief of Wards Auto World which issued a list of 10 best engines for BBC Auto.
In practice, it is different! "Generally, the turbo engine, you have to press the gas pedal to prevent the softer turbo pressure rises rapidly. In some small turbo engine, the driver presses the accelerator tend more quickly and deeply. As a result, high-pressure turbo: fuel consumption become more extravagant than the non-turbo engine with a larger, "said Winter.
Large capacity
The same thing can be seen in the V8 engine used Chevrrolet Corvette. According to CR, the fuel consumption of 8.9 km / liter, better than the 4-cylinder engine Mitsubishi Lancer Ralliart, 8.5 km / liter.
Another disadvantage small engine, smooth losing his big cc. Therefore, consumers prefer 6-cylinder engine. Engine power output 4-cylinder turbo V6 engine could be matched, but not for smooth working.
Turbo engine steady at a moderate pace. "In daily use, no need to frequently hit the gas. But when you are on a hill or accelerate from rest, usually the driver presses the gas pedal deeper. As a result, the actual acceleration is slow, "said Winter.
How to drive?
Motorists are generally more often complain wasteful fuel consumption car. The reason, they pressed the gas pedal faster when traffic jams. "This is what causes so wasteful fuel consumption," said Winter.
However, for some 4-cylinder turbo engine, but better performance than the non-turbo. This was proven by the machine used by German manufacturers, such as BMW, Audi and VW, both the sedan and SUV, specific capacity above 2.0 liters.
