STROKE BY STROKE FLOWMETER EM3 STROKE BY STROKE FLOWMETERMass measurement & opening/closing time of injectors A leadership • Responsive • Repeatable • Universal PRESENTATION Successor to the EMI2 used by all designers and manufacturers of petrol and diesel injectors, the EMI3 is a device intended to measure the volume injected. It also offers the measurement of opening and closing times for each injection. It allows a complete characterization of your injectors, in Research and Development or in production. APPLICATIONS • Automotive • Truck HIGHLIGHTS • A LEADERSHIP: More than 2000 systems sold worldwide. • RESPONSIVE: The correct measurement is immediately available regardless the variations between injections. • REPEATABLE: Very stable measurement of each volume injected thanks to a perfectly mastered measurement principle. • UNIVERSAL: Unique equipment for various uses: on table, integrated in an existing bench, in a complete EFS bench.

SYSTEM DESCRIPTION It’s made of: • a mechanics receiving the injector holder and the measuring system • an electronics managing the measurement cycle and performing all of the calculations at each turn, and two 8 meter cables • xEMI3 software, supervision interface between the user and the measuring device. Standard & HR EMI3 Injection volume: HR EMI3 : from 0 to 100 mm3 Standard EMI3 : from 0 to 600 mm3 Injection volume: Stainless steel EMI3: from 0 to 60

Measured parameters • Injected volume (mm3) • Injected mass (mg) • Injector's opening delay (ps) • Injector's closing delay (ps) • Instantaneous value • Average value • Minimum value • Maximum value • Standard deviation XEMI3 • Windows 10 • Ethernet link with the rack

Main control bar Connection MAIN FUNCTIONS • Display of all measurements on a single screen of the xEMI3 software: • Visualization of the EMI3 piston movement carried out in real time on the screen: the verification of the angular setting is thereby simplified. • Simultaneous display of injector control pulses (Cominj): the measurements validity is thus guaranteed. • Measure up to 5 injection volumes per revolution. • Time sampling for better accuracy: sampling at 200 ksps of the piston movement, sampling at 20 ksps of the temperature channels • Internal pulse generator to control your...

OSCILLOSCOPE FUNCTION (1) This function starts the display of instantaneous curves in an independent window: PLUNGER_LIFT signal or INJECTION_RATE signal. The display is automatically synchronized to the 1/Rev signal offset by the measurement setting angle. • The duration of a complete lap is displayed on the screen. • The display is in volume or in mass depending on the state of the current display mode. The Y axis of these curves is graduated in physical units: • in mm3 or in mg for the PLUNGER_LIFT signal • in mm3/ms or in mg/ms for the INJECTION_RATE signa

INJECTION MEASURES (2) Injection measurement characteristics of the EMI3 (to every rotation) • Injection start time (ps) • Injection length(ps) • Injected mass (mg) • Opening delay of the injector (ps) • Closing delay of the injector (ps) Start Time delay between 1/REV and injection start 220 Mass Instantaneous mass or volume of this injection Min, max, standard deviation of this measure when an average is in progress 502.0 375.0 Opening delay of the injector in ps Closing delay of the injector in ps Operator or technician Compatibility mode mode Operator Status: Alarms and faults active or...

Speed Signal This parameter defines here the synchronization signals that the EMI3 will use to clock its measurements. I Intemqf Clock Internal Clock They are generated: • either from an internal speed generator ■ • or from 2 external signals: 1/REV_IN and 3600/REV_IN • or from signals from an angular encoder 900 or 3600 lines Co mini OUT Pulse Generator Comini er/c aeon/r vt Coder -JEOTT*- ifT Coder OTO/T A+B + ivT Cominj OUT This signal is used to drive the injector. This is a 5V TTL output signal. It is sent: • either to an EFS IPoD, • or to another power generator capable of driving the...

To display masses, the software allows you to enter two density points of the fluid and its variation with temperature, generally at 20 ° C and 60 ° C. Compatilility mode The EMI3 can operate via the serial link in 8246 mode (MIQ) BNC 1 to BNC 4 Four analog outputs are available on the rear panel on BNCs. They make it possible to visualize in the form of an analog voltage from 0 to 10V, a measurement of the EMI3. Configuration...
