The Cummins QSK19-G4 generator-drive engine is a 19L inline six-cylinder diesel engine designed for standby, prime and continuous generator-set applications at 1,500 rpm and 1,800 rpm.
In the model-specific 50 Hz specification, the engine delivers 574 kW of gross prime mechanical power, 634 kW of gross standby mechanical power and 500 kW of gross continuous mechanical power at 1,500 rpm.
These mechanical ratings are not the final electrical output of the generator set. The referenced 50 Hz package produces approximately 520 kWe / 650 kVA prime, 572 kWe / 715 kVA standby and 451 kWe / 564 kVA continuous output.
The QSK19-G4 uses Cummins MCRS direct injection, electronic engine management, turbocharging and air-to-air charge-air cooling. It can be considered for OEM generator-set production, industrial power projects, replacement-engine programs and critical spare-engine inventories.

QSK19-G4 Engine Ratings and Generator-Set Output
The QSK19-G4 specification separates gross engine power, net engine power and typical generator-set output. These values represent different stages of power conversion and should not be used interchangeably.
| Frequency and Duty | Gross Engine Output | Net Engine Output | Typical Generator-Set Output |
|---|---|---|---|
| 50 Hz standby at 1,500 rpm | 634 kWm / 850 BHP | 609 kWm / 817 BHP | 572 kWe / 715 kVA |
| 50 Hz prime at 1,500 rpm | 574 kWm / 770 BHP | 555 kWm / 744 BHP | 520 kWe / 650 kVA |
| 50 Hz continuous at 1,500 rpm | 500 kWm / 670 BHP | 481 kWm / 645 BHP | 451 kWe / 564 kVA |
| 60 Hz standby at 1,800 rpm | 634 kWm / 850 BHP | 593 kWm / 795 BHP | 550 kWe / 688 kVA |
| 60 Hz prime at 1,800 rpm | 559 kWm / 750 BHP | 526 kWm / 705 BHP | 500 kWe / 625 kVA |
| 60 Hz continuous at 1,800 rpm | 459 kWm / 615 BHP | 425 kWm / 570 BHP | 400 kWe / 500 kVA |
The values above are based on a defined Cummins generator-drive specification. The final OEM rating must be confirmed using the selected cooling package, alternator-efficiency curve, power factor, driven-equipment losses, enclosure design and site conditions.
Why 574 kW Does Not Mean 574 kWe
The 574 kW prime figure is gross mechanical engine power. Part of this power is consumed by engine-driven equipment, and additional energy is lost during conversion from mechanical shaft power to electrical output.
| Power Stage | What It Represents | 50 Hz Prime Reference |
|---|---|---|
| Gross mechanical power | Engine output before the defined package losses | 574 kWm |
| Net mechanical power | Mechanical power remaining after the defined engine-side losses | 555 kWm |
| Electrical real power | Usable electrical output after alternator conversion | Approximately 520 kWe |
| Electrical apparent power | Generator-set output calculated at the applicable power factor | Approximately 650 kVA at 0.8 power factor |
The QSK19-G4 should therefore be positioned around the 650 kVA prime class at 50 Hz and the 625 kVA prime class at 60 Hz, rather than described as a 574 kW electrical generator set.
Published Rating Revisions
Cummins has published a model-specific QSK19-G4 specification and broader G-Drive rating cards. Their mechanical ratings remain consistent, but the estimated net and generator-set outputs can vary slightly because of document revision and package assumptions.
| Reference | 50 Hz Prime | 50 Hz Standby | 60 Hz Prime | 60 Hz Standby |
|---|---|---|---|---|
| 2019 model-specific specification | 520 kWe / 650 kVA | 572 kWe / 715 kVA | 500 kWe / 625 kVA | 550 kWe / 688 kVA |
| 2023 Cummins G-Drive rating card | Approximately 522 kWe / 652 kVA | Approximately 572 kWe / 715 kVA | Approximately 502 kWe / 628 kVA | Approximately 567 kWe / 708 kVA |
The commercial quotation should identify the performance specification or rating-card revision used for the proposed engine and generator package.
Prime, Standby and Continuous Ratings
The three published ratings describe different operating duties. The highest rating should not automatically be selected for long-duration operation.
| Rating | General Operating Duty | QSK19-G4 Selection Note |
|---|---|---|
| Emergency Standby Power | Emergency operation during interruption of a reliable utility source | The 634 kWm rating is not a normal long-duration operating point. |
| Prime Power | Unlimited annual operating hours with a varying electrical load under the applicable rating definition | The gross prime rating is 574 kWm at 50 Hz and 559 kWm at 60 Hz. |
| Continuous Power | Continuous operation at a relatively constant load up to the approved rating | The gross continuous rating is 500 kWm at 50 Hz and 459 kWm at 60 Hz. |
For isolated grids, industrial base-load systems and long-hour power stations, select the engine from the approved prime or continuous rating rather than the standby figure.
50 Hz and 60 Hz Are Separate Configurations
A four-pole main alternator normally operates at 1,500 rpm for 50 Hz and 1,800 rpm for 60 Hz. Although QSK19-G4 ratings are published at both speeds, an installed 50 Hz package should not be converted by changing engine speed alone.
| Selection Item | 50 Hz Configuration | 60 Hz Configuration |
|---|---|---|
| Rated speed | 1,500 rpm | 1,800 rpm |
| Gross prime power | 574 kWm | 559 kWm |
| Typical prime output | 520 kWe / 650 kVA | 500 kWe / 625 kVA |
| Gross standby power | 634 kWm | 634 kWm |
| Typical standby output | 572 kWe / 715 kVA | 550 kWe / 688 kVA |
| Gross continuous power | 500 kWm | 459 kWm |
| Typical continuous output | 451 kWe / 564 kVA | 400 kWe / 500 kVA |
The ECM calibration, fuel-system mapping, cooling package, main alternator, coupling, controller and protection settings must be verified for the required frequency.

QSK19-G4 Fuel Consumption
The original page incorrectly described 38.8 and 37.8 as values in g/kWh. In the model-specific specification, these values correspond to approximate U.S. gallons per hour. The official metric fuel-consumption figures are listed in litres per hour.
50 Hz Fuel Consumption at 1,500 rpm
| Operating Point | Gross Engine Power | Fuel Consumption | Approximate U.S. gal/h |
|---|---|---|---|
| 100% standby | 634 kWm | 161 L/h | 42.6 US gal/h |
| 100% prime | 574 kWm | 147 L/h | 38.8 US gal/h |
| 75% prime | 431 kWm | 111 L/h | 29.3 US gal/h |
| 50% prime | 287 kWm | 78 L/h | 20.6 US gal/h |
| 25% prime | 144 kWm | 40 L/h | 10.6 US gal/h |
| 100% continuous | 500 kWm | 128 L/h | 33.9 US gal/h |
60 Hz Fuel Consumption at 1,800 rpm
| Operating Point | Gross Engine Power | Fuel Consumption | Approximate U.S. gal/h |
|---|---|---|---|
| 100% standby | 634 kWm | 165 L/h | 43.5 US gal/h |
| 100% prime | 559 kWm | 143 L/h | 37.8 US gal/h |
| 75% prime | 420 kWm | 109 L/h | 28.7 US gal/h |
| 50% prime | 280 kWm | 77 L/h | 20.3 US gal/h |
| 25% prime | 140 kWm | 43 L/h | 11.3 US gal/h |
| 100% continuous | 459 kWm | 118 L/h | 31.2 US gal/h |
Actual site consumption varies with electrical load, generator efficiency, fuel properties, ambient temperature, altitude, idle time and engine condition. Use the approved performance curve when calculating guaranteed fuel cost or storage-tank capacity.
Dimensions and Weight
The published dimensions are engine-only installation references. They are not export packing dimensions.
| Parameter | Reference Value | Purchasing Note |
|---|---|---|
| Engine-only length | Approximately 1,695 mm | Confirm the arrangement drawing for the quoted configuration. |
| Engine-only width | Approximately 985 mm | Allow additional clearance for installation and service access. |
| Engine-only height | Approximately 1,723 mm | Intake, exhaust and lifting clearance may increase the required space. |
| Engine-only dry weight | Approximately 1,900 kg | Fluids, radiator, frame and accessories increase installed weight. |
| Export packing dimensions | According to the final packing list | Do not use engine dimensions as wooden-crate dimensions. |
| Shipping gross weight | According to the final packing list | Includes the confirmed supply scope, supports and packaging. |
Installation-critical values such as centre of gravity, allowable bending moment and rear-bearing load should be taken from the arrangement and installation documents applicable to the actual engine build.
Emission and Destination-Market Verification
The model-specific Cummins specification identifies EPA Tier 2 compliance for the QSK19-G4 at 50 Hz and 60 Hz. The original page also claimed Stage IIIA compliance, but that should not be stated without the certificate applicable to the quoted engine.
| Compliance Question | Required Verification |
|---|---|
| Which emission classification applies? | Confirm the engine-family statement and certificate covering the quoted ESN. |
| Is the engine accepted in the destination country? | Check current requirements for stationary, emergency, prime and rental generator installations. |
| Is exhaust after-treatment included? | Confirm the actual emissions configuration and supply scope before ordering. |
| Does the complete genset require certification? | Review electrical, safety, noise, enclosure and installation approvals separately. |
Origin and Manufacturer Verification
Chongqing Cummins Engine Company is a Cummins joint venture that manufactures heavy-duty and high-horsepower engines for industrial and stationary-power markets. However, the QSK19-G4 model name alone does not prove the production plant of every engine.
| Verification Item | Why It Matters |
|---|---|
| Manufacturer shown on the dataplate | Identifies the manufacturer stated for the specific engine. |
| Engine serial number | Identifies the actual production build and service information. |
| Configuration number | Supports verification of the engine arrangement. |
| CPL | Supports controlled-component and service-parts matching. |
| Test and traceability documents | Provide additional evidence when included in the confirmed supply scope. |
Describe the engine as a CCEC-manufactured unit only when this is supported by the actual dataplate and order documentation.
QSK19 Generator-Drive Selection
Current public Cummins information clearly lists QSK19-G4 configurations at both 50 Hz and 60 Hz, together with the higher-output QSK19-G5 at 60 Hz.
| Engine Configuration | Frequency | Typical Prime Output | Typical Standby Output | Rated Speed |
|---|---|---|---|---|
| QSK19-G4 | 50 Hz | 520 kWe / 650 kVA | 572 kWe / 715 kVA | 1,500 rpm |
| QSK19-G4 | 60 Hz | 500 kWe / 625 kVA | 550 kWe / 688 kVA | 1,800 rpm |
| QSK19-G5 | 60 Hz | 550 kWe / 688 kVA | 600 kWe / 750 kVA | 1,800 rpm |
For a 60 Hz project requiring more than approximately 500 kWe prime from the referenced G4 package, evaluate the QSK19-G5 or another correctly rated engine rather than assuming the G4 can be recalibrated to the required output.
Other QSK19 suffixes, including G11, G12, G13 and G14, should only be compared using their exact Cummins specification sheets, ESN records and CPL information. Do not assume that differences are limited to ECM software or that parts are interchangeable based on compression ratio alone.
When the QSK19-G4 May Be an Appropriate Choice
| Project Requirement | Why the QSK19-G4 May Be Considered | Important Check |
|---|---|---|
| Approximately 625–650 kVA prime | The referenced package provides 650 kVA prime at 50 Hz and 625 kVA prime at 60 Hz. | Confirm frequency, alternator efficiency and site derating. |
| Approximately 688–715 kVA standby | The referenced standby output is 715 kVA at 50 Hz and 688 kVA at 60 Hz. | Do not use standby output for normal long-duration operation. |
| Continuous industrial generation | The engine has published continuous ratings at both operating speeds. | Select the operating point from the approved continuous-rating documentation. |
| OEM generator-set manufacturing | Published mechanical, electrical and fuel-consumption data support initial package design. | Complete the radiator, alternator, controller and transient calculations. |
| Existing QSK19-G4 replacement | The same model may reduce integration work when the complete build matches. | Verify ESN, CPL, configuration, mounts, flywheel, controls and cooling interfaces. |
| Industrial sites using Cummins electronic service tools | The MCRS and electronic-control platform supports diagnostic and calibration workflows. | Confirm access to the correct service software, manuals and trained technicians. |
Generator-Set Application Scenarios
| Application | Project Consideration |
|---|---|
| Mining and remote industrial sites | Review altitude, dust filtration, fuel cleanliness, operating hours and critical-spares planning. |
| Factories and process plants | Calculate average load, motor starting, load sequence and required prime or continuous duty. |
| Data centres and telecommunications | Verify load-step response, UPS coordination, redundancy, controller integration and fuel autonomy. |
| Commercial and infrastructure backup | Calculate HVAC, lifts, pumps, fire systems, emergency loads and load-shedding priorities. |
| Utility and EPC projects | Use the approved engine specification, alternator data, cooling calculation and complete transient study. |
| Marine or offshore auxiliary power | Confirm whether marine classification, type approval and a marine-specific engine package are required. |
Replacement Compatibility Checklist
An engine carrying the QSK19-G4 model name is not automatically a direct replacement for every existing installation. Production revision, CPL, calibration and package interfaces must all be checked.
| Matching Item | Required Verification |
|---|---|
| Engine serial number | Identify the production build, service information and compatible parts. |
| CPL | Compare controlled components such as pistons, injectors, turbocharger and fuel-system parts. |
| Configuration number | Confirm whether D193103GX03 or another configuration matches the installation. |
| Performance-curve reference | Confirm the applicable power, emissions and operating conditions. |
| Frequency and speed | Confirm 1,500 rpm for 50 Hz or 1,800 rpm for 60 Hz. |
| ECM and calibration | Verify ECM hardware, calibration code, sensors and controller communication. |
| Flywheel and housing | Confirm the SAE housing, flywheel, coupling discs and alternator adaptor. |
| Engine mounts | Compare front and rear mounting positions, engine height and frame clearance. |
| Cooling system | Confirm radiator capacity, charge-air cooler, fan arrangement and enclosure airflow. |
| Fuel system | Verify supply, return, filtration, high-pressure components and shutdown arrangement. |
| Intake and exhaust | Check air restriction, turbocharger orientation, outlet positions and allowable back pressure. |
| Starting and charging | Confirm the 24V starter, batteries, charging alternator, cables and controller circuits. |
| Main alternator | Verify rated output, efficiency, excitation, inertia and mechanical interface. |
Do not claim a direct swap solely because the replacement engine has the same model name or CPL. The actual installation interfaces and supplied configuration must also match.
Parts Compatibility and Identification
Compression ratio alone is not a reliable parts-compatibility boundary. Engines with the same compression ratio may still use different injectors, pistons, turbochargers, sensors, ECM calibrations and overhaul-kit components.
| Identification Level | What It Confirms | Use in Parts Ordering |
|---|---|---|
| Engine model | General engine family and application | Suitable only for initial searching. |
| Engine serial number | Exact production build and service record | Required for accurate identification. |
| CPL | Controlled component grouping | Required, but should be used together with the ESN. |
| Current part number | Specific component and supersession path | Preferred reference for replacement parts. |
| ECM calibration | Electronic power and control configuration | Required for ECM or performance-related work. |
| Physical photographs and measurements | Connector, mounting and orientation details | Useful when the dataplate or records are incomplete. |

What is the difference between 574 kWm and 520 kWe?
The 574 kWm value is gross engine mechanical power. The 520 kWe value is the estimated electrical output after defined engine-side and alternator-conversion losses.
Is 38.8 g/kWh the correct fuel-consumption figure?
No. In the published table, 38.8 corresponds to approximately 38.8 U.S. gallons per hour. The metric fuel-consumption value at 100% 50 Hz prime load is 147 L/h.
What is the 60 Hz full-load fuel consumption?
The referenced fuel consumption is approximately 143 L/h at 559 kWm prime load and 165 L/h at 634 kWm standby load.
Is every QSK19-G4 a CCEC-manufactured engine?
Not necessarily. Confirm the manufacturer and production plant from the actual engine dataplate, ESN and traceability documents.
Does every QSK19-G4 use CPL 4270?
Do not assume so from the model name alone. Verify the CPL on the actual dataplate or through the engine serial number before selecting parts.
Are QSK19-G4, G5, G11 and G12 parts interchangeable?
Not automatically. Sharing a general engine family or compression ratio does not prove compatibility. Compare ESN, CPL, current part numbers, calibration and component specifications.
Are G13 and G14 parts incompatible only because of compression ratio?
Compression ratio may be one difference, but it is not the only compatibility criterion. Pistons, injectors, turbochargers, controls and other components must be verified individually.
