Researchers use TSI particle instruments for engine emissions research around the world. Our products help quantify and analyze particle emissions from light-duty and heavy-duty engines, for both on-road and stationary applications.
TSI products are used in the research and development of advanced internal combustion engines and aftertreatment systems, like diesel particulate filters (DPF) or gasoline particulate filters (GPF). Our particle counters quantify the number concentration of aerosol particles. TSI particle sizers measure the size distribution of exhaust particles.
Our instruments allow measurements at the tailpipe, from the Constant Volume Sampler (CVS), or from other partial flow samplers. TSI’s fast sizer spectrometers may also enable high time resolution mass measurements of engine exhaust particles.
In addition to testing specific vehicles, agencies and researchers use TSI instruments for air quality studies in communities. By driving and deploying our counters and engine fast sizers, they can quantify particle concentrations and size distributions from emissions near streets, freeways, ports, and airports.
Laboratory Engine Emissions Instruments
- Engine Exhaust Condensation Particle Counter 3790A detects nanoparticles larger than 23 nm per Euro 5b / Euro 6 regulations. When combined with a diluter and a volatile particle remover, the EECPC measures solid exhaust particles to PMP requirements.
- Engine Exhaust Condensation Particle Counter 3790A-10 designed specifically to meet upcoming Post Euro 6 regulations, and also satisfy requirements for UNECE R83 and R49.
- Engine Exhaust Particle Sizer (EEPS) 3090 measures the size distribution of engine exhaust particle emissions from 5.6 to 560 nm with the fastest time resolution available (10 Hz).
- Porous Tube Thermodiluter (PTT) 3098 is the next generation sample conditioning system specifically designed for the 3090 EEPS.
- 3095 Engine Exhaust Particle Measurement System provides accurate dynamic dilution control and measures the size distribution of engine exhaust particle emissions from 5.6 to 560nm in 32 channels with the fastest system time resolution available (10 Hz).
Real-world Field Emissions Testing
- Nanoparticle Emission Tester 3795 (NPET) measures nanoparticles in combustion emissions. It is particularly useful for construction machinery, buses, and other vehicles under realistic use conditions.
- High-Concentration NPET 3795-HC measures upstream and downstream of Diesel or Gasoline Particle Filters, cold start emissions, or biomass combustion emissions.
