Cummins compound turbos are engineered for performance, offering significant power, efficiency, and reliability improvements. These turbos use a twin-turbo setup, enhancing the performance of your engine across a wider range of speeds. Read on to learn about how Cummins compound turbos work and the benefits they bring to diesel engines.
What Are Cummins Compound Turbos?
Cummins compound turbos consist of two turbos working together in a sequential arrangement. This setup combines a smaller, high-pressure turbo with a larger, low-pressure turbo to deliver better airflow across all engine RPM ranges. The smaller turbo kicks in at lower RPMs to improve throttle response, while the larger turbo boosts the engine at higher speeds, providing more power and efficiency.
How Do Cummins Compound Turbos Work?
The key to the efficiency of Cummins compound turbos lies in their twin-turbo design. The process is as follows:
- Low-Pressure Turbo: The larger low-pressure turbo receives exhaust gases from the engine first. It compresses the air at lower speeds, allowing the high-pressure turbo to operate more efficiently.
- High-Pressure Turbo: The smaller, high-pressure turbo receives compressed air from the low-pressure turbo and forces it into the engine’s intake. This ensures the engine gets maximum airflow, especially under load and at higher RPMs.
By using both turbos, the system optimizes air compression across a broader range of engine speeds, allowing for smoother performance and increased power output without compromising fuel efficiency.
Benefits of Cummins Compound Turbos
- Improved Power and Efficiency: The compound turbo setup provides more horsepower and torque, especially at higher speeds. The sequential design ensures that the engine gets the right amount of boost at any RPM, leading to a more efficient use of fuel.
- Better Spool Time: The smaller low-pressure turbo allows the system to spool faster, minimizing turbo lag. This gives you a quicker throttle response and improved acceleration.
- Enhanced Reliability: By distributing the workload across two turbos, Cummins compound turbos reduce the risk of failure associated with a single turbo under high load. The system also cools more effectively, leading to better long-term engine health.
- Increased Towing Capacity: Compound turbos are especially beneficial for heavy-duty applications, such as towing. The increased torque and power output provide better performance when hauling heavy loads, making them ideal for trucks and large vehicles.
Conclusion
Cummins compound turbos are a powerful and efficient solution for improving the performance of diesel engines. By using two turbos in a sequential arrangement, these systems provide improved power, reliability, and fuel efficiency. Whether you’re looking to boost engine output or enhance towing capacity, Cummins compound turbos offer a solid upgrade for your diesel engine.
