Having a Turbocharger in your car is an important element in the process of producing more power and torque from your engine. The main purpose of a turbocharger is to force more air into the engine. This will allow the engine to produce more power for a given amount of displacement.Whether it's for performance or fuel economy, turbocharger technology has advanced rapidly in recent years. The latest innovations, including variable geometry turbochargers, have improved the performance and efficiency of modern engines. These technologies are now found in a wide variety of applications.Variable geometry turbochargers are turbochargers that have a small movable vanes.
This enables the turbine to adjust its speed and flow. Aside from maximizing efficiency, these devices can also reduce lag time, which increases power output.Variable geometry devices also manipulate the aspect ratio of the turbine, allowing for higher boost levels at lower engine speeds. Variable A/R ratios can also be used to keep exhaust back pressure low.Variable geometry turbochargers offer unique potential for mass-produced turbocharged engines. They are capable of matching engine power at any speed. While this technology is still relatively new for gasoline engines, it is becoming commonplace for diesel engines.Variable geometry turbochargers can be classified into two main types: rotating vane and sliding vane.
Rotating vane devices are suitable for light duty applications, while sliding vane devices are more suited for large engines.Unlike single-scroll turbochargers, twin-scroll turbochargers use pulse energy of exhaust gas to drive the intake air compressor. The design allows a turbocharger to produce high torque at low engine speeds. These turbochargers are commonly used on high-end gasoline engines.Twin-scroll turbochargers are not as efficient over the full rev range as the single-scroll turbochargers. The twin-scroll design uses an exhaust manifold split into two headers based on the firing order of the engine. The advantages of the twin-scroll design include an optimal low-end response and an excellent top-end power increase.The twin-scroll design also allows higher boost pressure at lower engine speeds. Compared to single-scroll turbochargers, the twin-scroll design is less sensitive to long-duration camshafts.
The two headers also help to reduce the reversion of exhaust gases, which may cause the intake manifold pressure to drop.The twin-scroll design is also more efficient than the single-scroll design in the turbocharging department. The twin-scroll design uses the same components in the turbocharger housing as the single-scroll design. It also features the latest performance technologies.Compared to a single scroll turbo, a twin scroll turbocharger is a faster and more efficient way to generate power. These turbos are designed to use more air on every stroke, cramming more air into the engine, and they can be installed on 4- and 6-cylinder engines.
