Description
Engine oil loss is a serious issue in current engine development. Downsizing combined with turbocharging, thinner pistons and higher cylinder pressures all contribute to oil consumption. To reduce it, engineers need to know under which engine operating conditions it occurs.
Time-resolved oil consumption profiles, especially in transient engine operation, require a real-time measuring instrument. The V&F LubeSense was developed for this purpose: combined with the V&F GasOxidizer, it determines oil consumption online using the SO2 tracer method.
Typical applications
- Oil consumption measurements on combustion engines
Application examples
Automotive industry
- Oil consumption measurements on combustion engines
Measurable compounds
- Oil consumption measurement: O2, H2O, SO2
Values marked as application-dependent (measuring range, response time, detection limit, gas consumption) depend on the compounds measured, the system configuration and the instrument settings.
