IC engine oil consumption measurement comprises use of radioactive tracer in lubricating oil and detector for oil in crankcase gases

摘要

The process comprises marking the engine lubricating oil with a radioactive tracer, passing crankcase gases from the engine cylinder block through an oil separator (2), and using a detector (3) that is sensitive to the ionising radiation emitted by the unseparated oil in a trap (4), transmitting the results to a computer (5) that can calculate the amount of oil consumed.
