RT-Ash Instrument
Ash Particle Size Distribution in Engine Exhaust
The Real Time Ash (RT-Ash™) instrument has been developed to measure real time ash particle number and size distribution from the exhaust of an internal combustion engine, regardless of the fuel, oil, and the engine technology used. The application of the RT-Ash instrument provides benefits in characterizing:
- Ash particle emissions from internal combustion engine
technologies
- Diesel
- Gasoline
- Natural gas
- Locomotive
- Two-stroke, four-stroke
- Ash particles at inlet and outlet of exhaust particle filters
- Diesel particulate filter (DPF)
- Gasoline particulate filter (GPF)
- Lube oil consumption marker under steady-state and transient engine operation
- Ash particle number, surface area, volume, and mass weighted size distributions
- Leaks caused by:
- Valve stem seals
- EGR coolant
- Turbo oil
- Others
- Ash content in lube oil and fuel
