Increasing power of auxiliary equipment driven by motor vehicle internal combustion engine involves direct change by changing unloaded revolution rate, indirect change to higher unloaded state speed

摘要

The method involves operating the engine at a first revolution rate (n) in the unloaded state and operating it at an increased unloaded revolution rate in the unloaded state on demanding an increased power output from an auxiliary device. The power output change is carried out directly by changing the unloaded revolution rate and indirectly by the engine changing from higher engine revolution rates to the unloaded state at the higher unloaded revolution rate.
