Comparison of advantages and disadvantages of the types of engine boost system
Turbo
Representative models: Bora 1.8T, Saab 9-32.0T, Volvo S802.5T, Audi A4L2.0TSI (turbo direct injection turbocharged engine), Les Shuanglong special II (common rail diesel engine)
Advantages: high pressure effect, fuel economy is better
Disadvantages: the power output of the engine is slightly behind the opening of the throttle
Twin turbo
Representative models: BMW X6xDrive35i, BMW 335i, Maybach 57S/62S, Peugeot 6072.2HDI
Advantages: ease the "turbo lag" phenomenon
Disadvantages: "expensive" on a word
Twin turbo is for exhaust gas turbocharging turbo lag, increase a low-speed turbine. At low engine speed, less exhaust can drive the turbine to rotate at high speed to generate sufficient air intake pressure, when the rotational speed of the engine after upgrading to. High speed turbine to enter values for high pressure state, and provide a coherent strong power. To a certain extent, the "turbo lag" phenomenon has been alleviated to a certain extent. Although the "turbo lag" phenomenon can not be completely eliminated, but in the actual use of the driver has been very difficult to detect the vehicle in the acceleration process of the driving force behind.
