Requirements on off-highway diesel engines

• Low-end & robust design, design life up to 15'000 h• Flexible & modular design• Multiple auxiliary drives, different flylwheel sizes• Inclination capability (up to 45°)• Rated power at low rpm (Down speeding)• High torque rising• Low fuel consumption• Engine cold start with hydrostatic towing load• Quietness (noise & vibration)• Operational reliability also with low-grade fuel and

lubricating oil• Easy servicing, maintenance interval > 500 h• Low life cycle costs
