Twin-scroll turbochargers are a type of forced induction system that is becoming increasingly popular in the automotive industry. These turbochargers work by using two separate exhaust gas inlets that are divided by a partition in the turbine housing. This design allows for more efficient use of exhaust gases, resulting in quicker spooling and improved throttle response. In addition, twin-scroll turbochargers can increase engine power and torque while reducing emissions. These benefits make twin-scroll turbochargers a popular choice for high-performance vehicles, and they are commonly found in sports cars and luxury vehicles.
