Key Differences between Sequential and Parallel Turbocharger Systems
While both sequential and parallel turbocharger systems are used in diesel engines, there are key differences between the two. Here’s an in-depth look at both systems:
Sequential Turbocharger System
A sequential turbocharger system is one in which each turbocharger is connected to a separate manifold, with the exhaust gas flowing through each turbocharger in sequence. This configuration allows for efficient exhaust gas flow and optimal turbocharger performance.
- The sequential turbocharger system is commonly used in engines such as the 6.7 Cummins engine, where the exhaust gas flows through a single turbocharger before entering the exhaust manifold.
- The sequential turbocharger system allows for improved engine efficiency and reduced emissions.
Parallel Turbocharger System
A parallel turbocharger system, on the other hand, is one in which multiple turbochargers are connected to a single manifold, with the exhaust gas flowing through each turbocharger simultaneously. This configuration allows for increased power output and reduced turbo-lag.
- The parallel turbocharger system is commonly used in high-performance engines, where increased power output is required.
- The parallel turbocharger system allows for improved engine performance and reduced turbo-lag.
Difference in Turbocharger Layouts
