More Technical Data
Engine Exhaust Manifold: Optional for Wet Exhaust manifold Heat exchanger
Aspiration: Turbocharged/Aftercooled
Compression Radio: 14.5:1
Fuel System: Cummins PT Pump, Direct Injection
Starting System: Electrical starting motor (24V)
Cooling Method: Water cooling
Lowest Starting Temp (Without auxiliary system): -12℃
Governor Type: Mechanical Control
Technical Advantages: PT Fuel System & STC Injectors
The heart of the CCEC Cummins KTA19-G2 336KW genset engine is its mechanical simplicity. Unlike high-pressure common rail systems, the KTA19-G2 PT fuel system uses a Pressure-Time principle that is famously resilient to varying fuel qualities.
- STC Injector Benefits: A major advantage for standby power engines for data centers is the Step Timing Control (STC) system. This allows the engine to optimize timing during startup and light loads, ensuring a -12℃ low temperature start without auxiliary systems and reducing "wet stacking."
- Aspiration: Featuring turbocharged aftercooled aspiration, this engine maintains an efficient 83 L/Kw.h fuel consumption at rated power while providing the rapid load response necessary for hospital emergency power.
Application Guide: 400kVA to 450kVA Generator Matching
Choosing the right alternator is critical for system stability. Our KTA19-G2 alternator matching guide recommends pairing this unit with a Stamford UCI274 or HC4 frame.
- Prime vs. Standby: It is vital to understand the KTA19-G2 336kW prime power vs standby power rating difference. While it delivers 336kW for continuous use, it can reach 369KW standby power for emergency spikes.
- Environmental Limits: The Cummins KTA19-G2 altitude deration and temperature limits are superior to many competitors; it can maintain performance in high-altitude mining sites and tropical climates up to 40°C.
- Installation: With a 1926kg lightweight design and dimensions of 1324mm x 835mm x 1183mm, it is perfect for containerized 400kVA gensets used in telecom tower backup or mobile generator sets.
Fuel Consumption and Operating Efficiency
At 1500RPM, the Cummins KTA19-G2 engine demonstrates efficient fuel consumption (~83 L/kW·h under rated conditions). Compared with larger engines such as KTA38, it provides better fuel economy for medium-load applications.
The engine supports both prime power and standby power modes:
- Prime power: continuous operation under variable load
- Standby power: emergency use with higher output (up to 369kW)
Altitude deration and turbocharging ensure consistent output even in demanding environments.
Generator Matching and Installation Guidance
The KTA19-G2 is commonly matched with alternators such as:
- Stamford HC4 series
- Marathon generators
- Leroy Somer alternators
Key installation considerations:
- Proper alternator sizing for 400–450kVA output
- Adequate cooling and ventilation
- Fuel system calibration for load profile
- Space planning based on dimensions (approx. 1324×835×1183mm)
