TSI Incorporated will launch the 3098 Porous Tube Thermodiluter (PTT) at this year’s show. The PTT is a fully integrated sample conditioning system designed to work seamlessly with TSI’s 3090 Engine Exhaust Particle Sizer (EEPS) spectrometer. Together, these instruments help researchers measure and analyze particle emissions from automotive and heavy-duty engines.
The EU is currently developing post-Euro 6 and Euro VI emissions standards for on-road vehicles, recommending lowering the size cut-off for particle counting from 23nm to at least 10nm. TSI claims the PTT is an effective response to these upcoming requirements.
“Our new PTT diluter employs two porous tube diluters, plus a catalytic stripper, to efficiently remove semi-volatile particles,” said Francisco Romay, senior product manager at TSI. “This diluter design has no moving parts and offers very low particle losses for sub-23nm particles.”
The system also provides real-time low dilution ratios, making the PTT 3098 ideal for characterizing transient particle emissions from modern engines post-aftertreatment. It also enables higher dilution ratios for engine-out measurements.
Customers can now measure particle size distribution more accurately, in alignment with PMP-compliant sub-23nm solid particle number measurements.
