Nearly perfect power system: dual supercharged Technical Analysis

Customarily seen pressurization system, generally divided into the the supercharger Supercharger and turbo Turbocharger two kinds of the two supercharged way each has its advantages and disadvantages. Supercharged use history are more established than the turbo, the first supercharged racing in the 1920s, Grand Prix (Grand Prix), and, in the ensuing days, because its engine the help of the power output, so a wide range of applications, supercharged advantage of low rpm output torque and power output of the linear performance engine technology is not high historical environment, supercharged system does make The car's power output has been improved, but this supercharged biggest drawback is high to increase the pressure and power decreases rapidly, of course, for noise control and the engine is running smoothly supercharger systems are more difficult to control.Roots blower-type supercharger, a wider application of one of the forms in the European system models, the common M.Benz supercharged models use this fan.

As for the turbo system that appears late in the year, the earliest such equipment exhaust turbocharger system models Corvair, Chevrolet (Chevrolet) turbo system is an effective way to improve engine efficiency and combustion efficiency auxiliary intake system, turbine blades from the engine exhausts to promote, to help improve the air flow rate and completely change the tradition of air into the cylinder by vacuum suction. But the turbo also has its drawbacks, low rpm, which is still not reached before the working status of the turbocharger, intake airflow is a significant barrier, resulting in the weak torque output of the engine in its infancy. Turbocharged roughly works before we have discussed before, two supercharged organically integrated and each of the essence, to its dregs many car manufacturers are trying to achieve, thereby giving rise to the concept of Twincharger .Dual turbocharging system first appeared in the 1985 Lancia Delta S4 rally car, although in the racing areas where the Dleta S4 was a great success, but the system will eventually because of the complex structure and high maintenance requirements, has not been able to in the other Lancia civilian models. This threshold was broken until the emergence of the Golf GT in 2005 was declared officially, Golf GT uses a single code for the the BLG's 1.4-liter inline four-cylinder TSI engine displacement is not high, but manufacturers announced peak horsepower up to 170 Torque 24.5 kg m BLG engines are one of the best examples of its the sibling rivals even leapfrog challenge.
