Description

The V&F GasOxidizer is a software-controlled tube furnace for oxidising the exhaust gas of combustion engines. It was developed to provide fast, time-resolved online measurement of engine oil consumption.

The method uses sulfur contained in the oil as a tracer. The sulfur passes through a chemical conversion in the combustion chamber, is determined in the exhaust gas and correlated with the oil consumed. In the SO2 tracer method the sulfur content is obtained by measuring sulfur dioxide (SO2) in the exhaust gas.

The GasOxidizer ensures that all sulfur components in the exhaust gas are measured as SO2: oxygen (O2) is added and converted to ozone (O3), which oxidises the sulfur species to SO2. SO2 is then quantified by ion-molecule reaction mass spectrometry (IMR-MS). This shortens measuring times and makes the low oil consumption of modern engines measurable.

Typical applications

  • Oil consumption measurements
  • Measurement of total sulfur
