Measuring fuel consumption of combustion engines on a chassis, engine and powertrain test stands
EXFM-ONE
Ultrasonic Exhaust Flow Meter
Real-time Measurement of Vehicle/Engine Exhaust Flow
EXFM-ONE employs an ultrasonic method for measuring exhaust gas flow rates directly from a vehicle or engine. The unit can be used for various applications such as real time mass measurement of raw exhaust gas combined with MEXA-ONE (Motor Exhaust Gas Analyzer), or for Particulate Matter/emission measurement combined with partial flow dilution system such as MDLT (Partial Flow Dilution Tunnel) or BMD (Bag Mini Diluter). Fuel consumption evaluation is also available when EXFM-ONE is paired with an optional air-to-fuel ratio (AFR) analyzer.
- Wide range of flow measurement: 0 m3/min to 10 m3/min
- Fast Response: Less than 0.5 seconds t10-90 response
- Integrated into HORIBA ONE PLATFORM or connected to host computer
Integrated Operating Platform
HORIBA ONE Series measurement devices such as MEXA-ONE and EXFM-ONE employ the newly developed software platform “HORIBA ONE PLATFORM”. The new platform enables the user to manage measurement and quality check results of EXFM-ONE and other devices on one single display. This single user interface increases efficiency and optimizes user control over the entire testing process.
EXFM-ONE Applications
- Real-time Mass Emission Measurement of Medium / Light-duty Engines
Engine and catalyst behaviour analysis during transient test cycles - PM Measurement of Medium / Light-duty Vehicles using MDLT
Flow control of partial flow sampling system such as MDLT at vehicle test
- Easy and Instantaneous Fuel Consumption Measurement
Real-time fuel consumption measurement of vehicles with an optional air-to-fuel ratio (AFR) analyzer
[Excellent correlation from idling to high speed driving]
[Rapid response after fuel shut-off operation]
