Scania rating

For continuous operation and unlimited yearly operation time at varying load. Max. mean load factor of 70% of rated power over 24 h of operation. 1 hour/12 hours period of accumulated peak overload to 110%. Power definition acc. to ISO 8528. Power test code: ISO 3046, continuous power, Net power. (Dependent auxiliaries per ISO 3046 not accounted for. Presence or absence of equipment which affects the final shaft output of the engine, alternator etc., see ISO 3046-1, 3.1.1) ISO 8528. DIN 6280 Dauerbetrieb.

 

Certain installations have other demands on power than those covered by ICFN, IFN, Patrol craft and PRP, for example engines with limited running hours, e.g. 500 h/y, but with mean output that might be high, e.g. engines for bow thrusters or engines with extremely few running hours and very high output requirements, e.g. fire pumps. For these types of installations, special considerations have to be made regarding cooling system, air intake etc. In such cases, please contact your Product Sales Manager at Scania. When we know more about the installation in question, we will help you to find a solution that fulfils your requirements on power and running hours as well as our demands on quality and reliability.

 

When talking about output for an engine, it should be noted that the ‘output’ depends on a number of physical circumstances which always have influence on the engine performance. The outputs stated in the Data Handbook have been determined under certain given test conditions according to the international performance standard ISO 3046. Output and other technical data applies to an engine under the following conditions:

 

Barometric pressure: 1000 mbar

Air temperature: 25°C

Relative humidity: 30%

 

Energy value: 42 700 kJ/kg

Density: 0.84 kg/dm3

Viscosity: 3.0 cSt at 40°C

 

For a new engine the brake output delivered may deviate from ‘sold output’ as ISO 3046 permits a tolerance of ±3%. According to our experience the output will also increase with 1.5-2% after a running period of 50-100 h.

 

At air temperature below -10°C or altitude above 2000 m the use of engine heater is recommended.
