Combustion motor e.g. diesel motor, loss determining method, involves determining loss as sum of determined load-dependent loss share, temperature-dependent loss share and gas exchange-loss share

摘要

The method involves determining load-dependent loss-share, temperature-dependent loss-share and gas exchange-loss share. A loss is determined as a sum of the load dependent loss share, temperature-dependent loss share and gas exchange-loss share. An indicated medium pressure in a high pressure phase is determined by measurement of pressure in a combustion chamber. The medium pressure in the phase is adjusted by an offset. Independent claims are also included for the following: (A) a method for controlling a combustion motor (B) a motor controlling device has a device for determination of loss of a combustion motor.
