1. Twin Turbo Technology
bis one turbocharger is a turbocharger manner. An exhaust gas turbocharger for turbo lag, one large series of the same two small turbine or turbines two parallel, at the time of engine low speed, low exhaust gas to drive the turbine to generate sufficient high-speed rotation of the intake pressure reducing turbo lag effect.
In the twin-turbo turbine car will see two groups connected by series or in parallel manner. Parallel refers to the work of each group is responsible for turbine engine half cylinders, each turbine are the same specifications, its advantage is pressurized fast response and reduce the complexity of the pipeline.
using the twin turbo, the pressurization system is the use of two independent turbocharger. When two interaction engine turbocharger, intake efficiency is significantly improved, the supercharging effect is more significant, greatly enhance dynamic. When engine speed is low, only a low-speed turbine work, which can be driven only less exhaust turbine rotates at high speed to produce a sufficient intake pressure, when the engine speed after the lift, the working speed turbo continues into high boost state value, providing a consistent strong momentum.
bis turbo technology while improving the engine power can be improved turbocharging “lag.” However, twin-turbo engine can not completely eliminate the “turbo lag” phenomenon, after all, the inertia of the turbocharger impeller remains. In actual use, typically twin-turbo engine equipped in a larger line 6-cylinder engine or a V-like displacement.
