Cummins QSC Turbochargers & Related Components

The turbocharger is one of the most important components of the Cummins QSC engine. It is the key system that allows this engine to produce high power output while maintaining efficiency and durability across marine and industrial applications. By forcing more air into the combustion chambers, the turbocharger enables the QSC to achieve greater horsepower, cleaner combustion, and improved fuel economy.

At Diesel Pro Power, we supply a complete range of turbo solutions for the Cummins QSC engine, including brand-new replacement turbochargers, the AirSep system for single-turbo configurations, high-temperature jointing compounds, and filtration components designed to protect the turbo system. With over 40,000 satisfied customers worldwide, our catalog is trusted by operators who depend on their Cummins QSC engines every day.

Turbocharger for Cummins QSC Engines

A replacement turbocharger for the Cummins QSC engine is precision-engineered to deliver reliable boost pressure, excellent throttle response, and long-term durability.

Key Features

• Optimized airflow: Designed to deliver the precise volume of compressed air required by the QSC for efficient combustion.

• Durable design: Built to handle high exhaust gas temperatures and sustained load conditions typical of marine and heavy-duty industrial applications.

• Improved fuel economy: Helps the QSC engine burn fuel more efficiently, reducing overall operating costs.

• Cleaner operation: Ensures lower smoke output and compliance with emissions standards in marine environments.

Installing a new turbocharger restores engine power, reduces black smoke, and can significantly extend the life of a QSC engine that has suffered performance loss due to turbo wear.

Cummins QSC AirSep System – Single Turbo

The AirSep system is specifically designed for Cummins QSC engines running a single turbocharger. It provides an advanced air filtration and separation solution that protects the turbocharger and engine from contaminants and oil mist.

Benefits of the AirSep System

• Cleaner intake air: Removes harmful particles and oil mist before they reach the turbocharger.

• Turbo protection: Extends the life of the turbo by preventing buildup and wear caused by contaminated airflow.

• Efficient operation: Maintains consistent airflow and supports proper boost pressure for the QSC.

• Marine-ready design: Built to withstand demanding marine conditions, where reliable air management is critical.

This system features a 4-inch throat diameter to provide the correct airflow for QSC turbo configurations. It is a popular choice for operators who want to maximize both performance and engine protection.

High-Temperature Jointing Compound for QSC Turbo Systems

Because the turbocharger on a QSC engine operates under extreme temperatures, ensuring a leak-free seal at exhaust joints is essential. A high-temperature jointing compound is used during turbo installation and maintenance to prevent exhaust leaks and maintain efficiency.

Features

• Extreme temperature resistance: Rated to withstand up to 760°C, perfect for turbo and exhaust manifold connections.

• Reliable sealing: Prevents power loss, exhaust leaks, and potential damage to engine compartments.

• Long-term performance: Reduces the risk of rework by maintaining a strong seal over time.

This compound is strongly recommended when replacing or servicing the turbo on a Cummins QSC engine to ensure maximum performance and reliability.

Air Cleaners for Cummins QSC Turbocharged Engines

The turbocharger can only perform at its best when supplied with clean, unrestricted airflow. High-quality air cleaners are essential to protect the QSC turbo system from dirt, debris, and moisture.

Advantages of Quality Air Cleaners

• Protects the turbo: Prevents foreign particles from damaging turbine blades and bearings.

• Sustains performance: Maintains proper airflow, allowing the turbo to deliver consistent boost pressure.

• Extends engine life: Reduces overall engine wear by ensuring only clean air enters the combustion process.

• Marine and industrial grade: Built tough for demanding QSC engine applications in vessels and heavy-duty equipment.

Replacing the air cleaner at regular service intervals is one of the simplest ways to protect both the turbo and the Cummins QSC engine as a whole.
