Abstract:
A method and system for determining steady state and real time engine oil consumption of an automotive engine which generates exhaust gases containing oil and fuel having a known sulphur content. The system includes an exhaust gas conditioner coupled to the exhaust manifold of the engine for extracting an exhaust gas sample and converting the exhaust sample into a combustion product. The system also includes a high temperature sampler for automatically regulating the amount of the combustion product independent of changes in back pressure of the engine. The system further includes a fluorescent detector for generating a sulphur dioxide content signal having a value corresponding to the sulphur dioxide contained in the regulated combustion product. Finally, the system includes a processor responsive to the value of the sulphur dioxide content signal to determine a steady state and/or a real time oil consumption of the engine based on the value of the sulphur dioxide content signal and the known sulphur content of the oil and fuel.
