KTTA50-G
Cummins

The Cummins KTTA50-G series represents the pinnacle of high-performance, high-displacement generator drive (G-Drive) technology. Designed and built for exceptional reliability in the most demanding environments, these heavy-duty V16 diesel engines provide the robust, continuous, and standby power essential for global infrastructure, major industries, and critical facilities. With advanced engineering focused on durability, fuel efficiency, and operational simplicity, the KTTA50-G series is the trusted power source where uptime is non-negotiable.
*Note: "TT" in KTTA50 indicates a Twin-Turbocharged configuration for enhanced performance. The exact power rating varies by specific model (e.g., G3, G8, G16) within the series.*
The KTTA50-G series is engineered as the prime mover for industrial and commercial diesel generator sets. Its primary application is providing G-Drive (Generator Drive) power across diverse and critical sectors:
Continuous & Prime Power: For mining operations, oil & gas fields, and large manufacturing plants where grid power is unreliable or unavailable.
Critical Facility Standby Power: Essential for safeguarding data centers, hospitals, airports, and telecommunications hubs against power outages.
Heavy-Duty Rental & Project Power: Ideal for large-scale construction sites, movie production, and events requiring temporary, high-capacity power in containerized units.
Specialized Industrial Applications: Including dynamic/rotary UPS systems, rail power, and crushing/mining operations.
1. Twin-Turbocharged Performance and Efficiency
The advanced Twin-Turbocharged (TT) and Aftercooled aspiration system delivers superior air intake efficiency. This design forces a greater mass of cool, dense air into the combustion chambers, enabling more complete fuel burn for maximum power output, improved fuel economy (as low as 202 g/kWh in optimal conditions), and reduced thermal stress on engine components.
2. Legendary PT Fuel System and Robust Design
At its heart is the renowned, mechanically simple, and highly reliable Cummins PT (Pressure-Time) fuel system. The engine features a heavy-duty integrated design for the cylinder block and head, which reduces the total number of parts by approximately 40% compared to traditional designs. This integration minimizes potential leak points and significantly enhances structural integrity and long-term durability.
3. Intelligent Control and Operational Resilience
Equipped with a precise electronic governor, the engine ensures excellent steady-state frequency regulation (typically within ±0.25%). It is engineered for outstanding environmental adaptability, capable of reliable operation at high altitudes and in ambient temperatures up to 50°C (122°F). The jacket water aftercooled design and step timing control system optimize performance across all load and temperature combinations.
