Main parameters

 

Power: 120 kW for normal use, 140 kW for standby use.
Voltage and Frequency: Output voltage is 400V/230V, frequency is 50 Hz, power factor is 0.8 (lagging), and it uses a three-phase, four-wire output system.
Engine Parameters: 6-cylinder in-line, bore × stroke 102 × 120 mm, displacement 5.9 L, compression ratio 17.3:1, intake system is supercharged with air-to-air intercooling, cooling system is a closed water-cooling cycle, and starting method is a DC 24V electric starter.

Performance characteristics

 

Powerful: Utilizing forged steel camshafts and crankshafts, and a high-strength cylinder block design, the engine boasts exceptional rigidity and high-pressure resistance, adapting to harsh operating conditions and capable of high-intensity, heavy-duty operation.
High Reliability: The engine has 40% fewer parts than comparable engines, significantly reducing the failure rate. Overhaul intervals are at least 20,000 hours, and Cummins offers a one-year or 1,000-hour warranty.
Fuel Efficiency: The rotary high-pressure fuel pump offers lower fuel consumption, effectively reducing operating costs.
Quietness: A silent hood, multi-layer soundproofing, and optimized air intake and exhaust systems effectively reduce operating noise. For example, the Baoda PDC165A unit in this series has a noise level of 80dBA at 1 meter and 70dBA at 7 meters.
