Product catalog summary
Overview: The D 2011L series is designed for generator sets with power outputs ranging from 12 to 31 kW (16 to 41 hp) at 1500 rpm, compliant with EU Stage IIIA emissions standards. These engines are oil-cooled, naturally aspirated, and available in 2-, 3-, and 4-cylinder configurations.
Key Features:
  • Direct injection with single injection pumps and optional electronic governor.
  • Low maintenance and wear, resulting in minimized running costs.
  • Excellent cold starting performance under extreme conditions.
  • Robust design for global operation, even with high sulfur fuels.
  • Optimized combustion for low fuel consumption.
  • Extended oil change intervals up to 1000 hours.
  • Immediate power supply due to good load response.
Technical Specifications:
  • Engine Types: D 2011L02 (2 cylinders), D 2011L03 (3 cylinders), D 2011L04 (4 cylinders).
  • Bore/Stroke: 94/112 mm (3.7/4.4 in).
  • Displacement: Ranges from 1.6 to 3.1 liters.
  • Weight: Varies from 224 kg to 303 kg.
  • Power Output: Continuous Power (COP) ranges from 11.8 kW to 27.9 kW, Prime Power (PRP) from 12.4 kW to 29.4 kW, and Limited Time Power (LTP) from 13.0 kW to 30.9 kW.
  • Fuel Consumption: Varies with load, with the lowest consumption at 75% load.
Performance and Efficiency:
  • Generator efficiency is considered at 89-90% with a power factor of 0.8.
  • Heat dissipation and cooling system specifications are provided for dimensioning purposes.
  • Inlet and exhaust data include maximum intake depression, combustion air volume, exhaust gas temperature, and flow.
Dimensions: Engine dimensions vary based on the model and scope of delivery, with detailed measurements provided for each engine type.
