Contained herein are certain points regarding the initial operation, the assurance of a reliable
service as well for overcoming the need for long periods of non operation, thus ensuring a rapid
return to service.
For any working data mentioned in this book, please bear the following in mind:
It is possible for the engine power to be limited before reaching its full performance capacity,
to meet special requirements. Thereby in compliance with DIN ISO 3046 we differentiate
between:
• Maximum continuous power
this is the maximum permissible output for this type of engine.
• Rated power
this is indicated on the acceptance test records for your engine.
• Full stop power
this is the power output limited by a restrictor on the injection pump racks.
Unless otherwise indicated, our information always refers to the maximum continuous power and if
this is unknown to the operator he should make inquiries to the manufacturer.
The power is limited by a restrictor at the fuel injection pump control shaft during the test bed run
and normally at rated power and speed. Any other arrangements can be seen from the acceptance
test records (
A1.10
).
Attention:
When using heavier fuel grades independent on the density of the fuel, the rated power
will be reached at a fuel rack position that is accordingly lower. As such, the limiting
position must also be accordingly lower. This is especially the case after a change of fuel
from that of an essentially higher density as it is the case when changing from distilled
fuel to heavy oil. The alteration of the fuel rack position may only be carried out by
personnel who have received permission to do this from Caterpillar / MaK !
