SYSTEM FOR MEASURING AN OIL RETENTION VOLUME IN A LUBRICATING SYSTEM

摘要

A system for measuring an oil retention volume of a first member of an engine lubricating system, the injected oil flowing inside the first member mixed with a first air volume, the mixture forming a first fluid, the measuring system including an oil injector at the inlet of the lubricating system; a first flowmeter to measure a first oil flow rate at the inlet of the lubricating system; a second flowmeter at the outlet of the first member to measure a second flow rate of the first fluid at the outlet of the first member; a measuring device to calculate a first value representing a quantity of oil in a volume of the first fluid flowing inside the first member; a calculator to calculate a third oil flow rate at the outlet from the second flow rate of the first fluid measured and the first value calculated and the instantaneous oil retention volume in the first member from the comparison of the first oil flow rate with the third oil flow rate.

主权项

1. A measuring device enabling a first value to be calculated at a given instant representing a quantity of oil in a given volume of a first fluid, said first fluid being a mixture of a volume of oil and of a first air volume, said measuring device being suitable for correcting, from the first value, a flow measurement of a flowmeter which measures a volume of oil at an outlet of a member of a lubricating system of an engine.
