GMS 141 Sampling System
GMS 141 gravimetric sampling system of oil concentrations at Blow-By oil mist separators
The GMS 141 gravimetric sampling system allows the comfortable detection of oil content in blow-by after oil mist separators with a flat sheet filter at engine test stands.
Oil mist separators must be improved to reach new engine exhaust reglementations. It is also designed to capture oil wall films for engine protection.
Oil mist separators are basic components of a crankcase ventilation system. They will be benchmarked after differential pressure and oil flow. For chosing a most suitable type of oil mist separator for a new type of engine these measurements are essential.
