KTA38-G2B
Cummins

The Cummins KTA38-G2B is a premium 38-liter V12 diesel engine, engineered to be the cornerstone of heavy-duty power generation. Designed specifically for generator-drive (G-Drive) applications, this engine delivers exceptional power density, legendary durability, and outstanding fuel efficiency for mission-critical operations. Whether for continuous prime power, reliable standby backup, or demanding industrial projects, the KTA38-G2B provides the robust performance needed to keep businesses and infrastructure running smoothly.
The engine is designed to operate seamlessly across global power grids, offering dual-frequency capability:
50 Hz Operation (1500 RPM): Prime Power: 711 kW (953 HP); Standby Power: Up to 790 kW (1058 HP).
60 Hz Operation (1800 RPM): Prime Power: 830 kW (1112 HP); Standby Power: Up to 920 kW (1233 HP).
The KTA38-G2B is the driving force behind large-capacity industrial and commercial generator sets. Its primary application is for G-Drive (Generator Drive) installations, providing reliable power across various critical sectors:
Prime & Continuous Power: Ideal for mining operations, oil & gas fields, and large manufacturing plants where grid power is unavailable or unreliable.
Emergency Standby Power: Essential for safeguarding hospitals, data centers, airports, and telecommunications facilities against power outages.
Construction & Infrastructure: Provides reliable on-site power for large-scale projects, including commercial buildings and government facilities.
Rental & Mobile Power: Well-suited for large-capacity, containerized or mobile generator sets used for temporary power or events.
1. Legendary Cummins PT Fuel System
At its heart is the renowned Cummins PT (Pressure-Time) fuel system, known for its mechanical simplicity, ruggedness, and precise fuel delivery. This system ensures optimal combustion, contributing to the engine's excellent fuel efficiency and reliable operation even with varying fuel qualities.
2. Advanced Turbocharged & Aftercooled Design
Featuring an advanced turbocharged and aftercooled (TTA) aspiration system, the engine forces a greater mass of cool, dense air into the combustion chambers. This enables more complete fuel burn for maximum power output and efficiency while reducing thermal stress on engine components for extended life.
3. Heavy-Duty Construction for Durability
Engineered for longevity, it features a robust V12 configuration with a high-strength structure. Key durability features include wet and replaceable cylinder liners for better heat dissipation and serviceability, and an optimized cooling system with a gear-driven water pump for effective thermal management.
