MODEL BMT-2000 is Micro Dilution Tunnel System based on test regulations in each country.
This system uses proportional sampling method, by which ratio of sampling flow rate split from engine exhaust gas and exhaust gas flow rate is kept stable.
It has wide split ratio (1/600〜) and applies to various large and small engines. The system response time is 200msec by our original engine exhaust gas split flow gas system and accurate flow rate of generating dilution gas, which is allowed by accurate VFM (Venturi Flow Meter) and high speed solenoid proportional valve included our own know-how about flow rate control.

●Transient and steady state testing
　System response time is 200msec.
●More accurate
　More accurate control of split flow rate is
　realised by high speed solenoid proportional
　valve and accurate VFM.
●Wide split ratio (1/600〜)
　Apply to various large and small engines.
●Based on test regulations of each country
　ECE-R49(88/77/EEC), 91/542/EEC,
　ISO8178, 8877, 16183, EURO III ESC,
　EURO III ETC, USA(CFR), JPN(TR002-01).
●Easy operation with the software included
　functions such as automotive calibration
　etc.
●Compact size
　Easy to use in a factory and move there
　engines.
