Method and device for estimating and indicating the state of wear of lubricating oil of a diesel engine

According to the invention, this method consists: in adding up the number n of revolutions performed by the engine with a weighting coefficient yj depending especially on the load and speed Nj; in deducing from this weighted number of revolutions n the quantity q of carbon-like particles accumulated...

Beschreibung
Zusammenfassung:	According to the invention, this method consists: in adding up the number n of revolutions performed by the engine with a weighting coefficient yj depending especially on the load and speed Nj; in deducing from this weighted number of revolutions n the quantity q of carbon-like particles accumulated in this lubrication oil; and in giving a warning signal when a limit quantity ql is attained, in order to perform an oil change. Application: especially to an indicator of the necessity of changing the oil for a diesel engine. SUIVANT L'INVENTION, CE PROCEDE CONSISTE: A TOTALISER LE NOMBRE N DE TOURS EFFECTUES PAR LE MOTEUR AVEC UN COEFFICIENT DE PONDERATION Y DEPENDANT NOTAMMENT DE LA CHARGE ET DU REGIME N; A DEDUIRE DE CE NOMBRE DE TOURS PONDERE N LA QUANTITE Q DE PARTICULES CHARBONNEUSES ACCUMULEES DANS CETTE HUILE DE GRAISSAGE; ET A FOURNIR UN SIGNAL D'ALERTE LORSQU'UNE QUANTITE LIMITE Q EST ATTEINTE, POUR EFFECTUER LA VIDANGE.APPLICATION: NOTAMMENT A UN INDICATEUR DE NECESSITE DE VIDANGE POUR UN MOTEUR DIESEL.
