Ion molecule reaction mass spectrometer


Fuel that is mixed with engine oil has a significant influence on the lubricating properties of the engine oil and consequently on the friction and wear of components in the combustion engine. Increased amounts of fuel in the engine oil lead to a reduction in the oil viscosity and consequently to reduced friction as well as to increased wear.

Especially for transient engine operation, a device for real-time measurements is indispensable to obtain time-resolved oil dilution values. The V&F FuelSense has been specifically designed for this task. In combination with the V&F LubeSampler oil dilution can now be determined on-line.
