RATING GUIDELINES

1. LOAD RATINGS 1.1 *Maximum Rating may be used for intermittent load applications (full throttle operation is cyclically interrupted) where the

average load factor does not exceed the continuous rating, and where full throttle operation does not exceed 60 minutes without interruption.

1.2 *Continuous rating may be used for constant load applications requiring uninterrupted service at full throttle for extended periods of time and for Water Management applications.

2. SPEED RATINGS2.1 If the application qualifies for the continuous load rating the governor cut-in point shall be set within the limits of the solid line

portion of the continuous curve. 2.2 If the application qualifies for the maximum load rating the governor cut-in point shall be set within the limits of the solid line

portion of the maximum curve.

3. DEFINITIONS3.1 Load (Speed) factor is defined as the arithmetic mean of the Load (Speed) profile of the normal duty cycle, not including

prolonged periods of idle operation.

4. INTERNATIONAL RATING GUIDELINES

*These ratings represent gross engine performance capabilities obtained and corrected in accordance with SAE J1995 and the conditions as stated on the front of the curve. The ratings are in conformance with the requirements specified in ISO 3046, BS 5514 and DIN 6271. Although these specific standards have a note excluding road construction, earth moving equipment, agricultural tractors and industrial trucks as applications not covered by the standard, these are included as acceptable applications of these ratings. The Maximum Rating conforms to ISO 3046 overload power and fuel stop power. The Continuous Rating may be used for continuous service in commercial applications and it conforms to ISO 3046 continuous power. Reference standards: BS 5514 and DIN 6271 standards are based on ISO 3046.
