Abstract
Procedure to operate a combustion motor in the event of damage, whereby the thermoelectric voltage of a lubricant interruption on parts moving relative to each other and made of different, electrically conducting materials, is used to initiate an alarm signal, in that upon the appearance of such an alarm signal at least one operating parameter of the combustion engine is changed until the alarm extinguishes and the combustion motor is then further operated in a reduced operational state.
Claims10
A method to operate a combustion engine in the event of damage, whereby the thermoelectric voltage of a lubricant break on parts moving relative to each other and made of different, electrically conducting materials is used to initiate an alarm signal, characterized by an operating parameter of the combustion engine being changed upon the appearance of such an alarm signal until the alarm extinguishes and the combustion engine is further operated in a reduced operational mode, and said thermoelectric voltage used comprising the thermoelectric voltage from frictional bearings, wherein said at least one operating parameter of the combustion engine changed upon the appearance of said alarm signal comprises reducing the power for an attached unit supplied from the combustion motor.
A device to operate a combustion engine in the event of damage, whereby the thermoelectric voltage of a lubricant break on parts moving relative to each other and made of different, electrically conducting materials is used to initiate an alarm signal, wherein said thermoelectric voltage used comprises the thermoelectric voltage from frictional bearings, and wherein an operating parameter of the combustion engine is changed upon the appearance of such an alarm signal until the alarm extinguishes and the combustion engine is further operated in a reduced operational mode;
- wherein said at least one operating parameter of the combustion engine changed upon the appearance of said alarm signal comprises reducing the power for an attached unit supplied from the combustion motor, the device further comprising:
- an acquisition device connected on the one hand with the housing by means of lines and on the other hand with the motor shaft of the combustion motor, which emits an alarm signal upon the appearance of a significant thermoelectric voltage, characterized by the acquisition device being connected to a control device to control at least one regulating device for at least one operating parameter for the operation of the combustion motor.
