METHOD FOR ASSESSING CONDITION OF DIESEL ENGINE FUEL PUMP GOVERNOR Russian patent published in 1994 - IPC

FIELD: diagnostics of machines. SUBSTANCE: method involves setting a certain rotation speed corresponding to start of governor operation, then carrying out a series of accelerations each time measuring acceleration at the first rotation speed which is lower than the preset one, determining the variation coefficient of measured accelerations. Then additional series of accelerations are performed. In each additional series the acceleration is measured and the variation coefficient of measured acceleration is determined at the rotation speed which is higher than that determined in the preceding series of accelerations. The start of governor operation is determined by the maximum values of variation coefficient. EFFECT: higher efficiency. 2 dwg
