Fuel that is mixed with engine oil has a tremendous influence on the lubrication characteristics of the engine oil and results in varied friction and wear behavior of engine parts. Increasing mass fractions of fuel components in the engine oil lead to a reduction on oil viscosity. This can lead to lower friction but increased wear.
Especially for transient engine operation real-time measurement instrumentation is obligatory in order to obtain time resolved oil dilution profiles. The V&F FuelSense has been specifically designed for this task. In combination with the V&F LubeSampler oil dilution rates can now be determined online.
