PTO & Mounting Configurations

 

Flywheel Housing Options: Standardized SAE #3 and SAE #4 housing options for flexible alternator coupling.

 

Flywheel Connections: Compatible with 8.5-inch and 10-inch flexible drive plates in accordance with ISO 3046 standards.

 

Power Take-Off (PTO): Gear-driven auxiliary front PTO supplying up to 120 Nm torque for hydraulic pumps or cooling fans.

 

Crankshaft PTO Extension: Standard cylindrical keyed or splined shaft stubs for industrial pump drives.

 

Turbocharging & Fuel Injection System

2,200 Bar Common Rail:

High-pressure fuel injection optimizes fuel atomization and reduces particulate buildup.

Variable Geometry Turbocharging:

VGT continuously adjusts vane geometry to eliminate turbo lag at lower RPMs.

Charge-Air Cooling:

An air-to-water intercooler maintains intake temperatures below 45°C, preventing thermal power derating under continuous high loads.

 

Operating Conditions & Duty Ratings

Prime Power Rating (PRP):

Continuous operation under variable load with a 10% overload capability for 1 hour per 12 hours.

Emergency Standby Rating (ESP):

Maximum power delivery during utility outages up to 200 operating hours annually.

Continuous Power Rating (COP):

Constant 100% load operation for utility base-load applications.

Specific Fuel Consumption:

198 g/kWh fuel consumption at 75% load operating point.

 

OEM Custom Options

 

• Private-label engine nameplates with laser-etched OEM branding and serial numbers.
• Custom ECU wiring harness lengths with optional IP67-rated waterproof connectors.
• Custom powder coating for engine blocks and mounting frames in OEM RAL colors.

 

Quality Control & Performance Verification

01/

100% Dynamometer Testing: Every engine undergoes a multi-stage load test on a digital dynamometer before packing.

02/

Pressure Leak Testing: 100% pneumatic leak checks conducted on oil, coolant, and fuel circuits.

03/

Electrical System Inspection: ECU sensor calibration, harness continuity testing, and automated safety shutoff validation.

04/

Inspection Traceability: Test logs recorded by engine serial number and archived for customer audit upon request.

FAQ

 

Q: Which duty rating does the published 140 kW rated power correspond to?

A: The 140 kW rating corresponds to Prime Power (PRP). Continuous Power (COP) output is approximately 127 kW, while Emergency Standby Power (ESP) allows a short-term peak of up to 154 kW.

Q: What emissions standard does the EGR+DOC+DPF+SCR aftertreatment package meet?

A: This aftertreatment configuration is calibrated to meet EU Stage V and US EPA Tier 4 Final emissions standards, with AdBlue consumption rated at approximately 3-5% of diesel fuel consumption.

Q: What types of equipment is this engine typically matched to?

A: This engine platform is most commonly matched to generator sets in the 100-150 kVA range, as well as mid-size water pump sets and hydraulic power units requiring the front PTO output.

Q: Can the engine be de-rated for use at high-altitude installation sites?

A: Yes, standard derating curves apply above 1,000 meters elevation, with turbocharger and ECU mapping adjustments available at order to maintain usable output at sites up to 3,000 meters.

Q: How quickly can critical spare parts be shipped internationally for units under warranty?

A: Critical components such as injectors and ECU sensors are dispatched via air freight within 48 hours of a confirmed order for units still under the standard warranty period.

Q: What is the difference between the 5-unit MOQ and 20-unit OEM MOQ requirement?

A: The 5-unit MOQ applies to standard catalog engine configurations, while the 20-unit threshold applies specifically to fully customized OEM builds involving non-standard ECU mapping, harness length, or branding requirements.
