1 World leader in alternative fuel systems

2 VSI-2.0 DI LPG introduction The Prins VSI-2.0 DI LPG system based on the vapour sequential technology (including Keihin injectors) is currently suitable for the complete range of VAG vehicles (Volkswagen/Audi/Seat/ Skoda) with 1.4TSI (CAXA) engine and PSA vehicles (Peugeot/Citroen) with 1.6 THP (EP6CDT/5FV) engine. This product recently won the INPRO award at GasShow 2014 in Poland. Download the product flyer HERE

3 VSI-2.0 DI LPG overview

4 USPs VSI-2.0 DI Most advanced vapour sequential LPG DI system on the market! Low petrol consumption, less than 5%! Equal driveability/engine power output compared to petrol Flexible installation Dedicated engine kit Easy installation Same proven hardware as VSI-2.0 LPG Applicable for wide range of models with same engine code R115 certified Emission reduction Up to 95 % less particle emission Up to 12% less CO 2 emission

10 Injector Module VSI-DI Individual interruption and simulation for each petrol DI-injector. 4- and 6 cylinder versions available. Three variants available [A/B/C]. Suitable for most direct petrol injectors. Cylinder selective switching between gas <->petrol possible. Petrol injection signal output for AFC. IM temperature monitoring [AD-5 wiring]. Fast Power-FET based control. Waterproof connector and housing.

11 IM variants 3 variants: A / B / C Hardware specific characteristics A and B module are interchangeable without changing fueling calibration C module effects fueling calibration. Always use right module according to dedicated conversion kit.

12 Injector Module petrol operation Petrol_mode: IM_com => 0 volt, dummy circuit is not activated. Injector supply straight through petrol injector. Petrol injector ground-switched by petrol ECU. Voltage selection controlled by petrol ECU.

13 Injector Module LPG operation LPG_mode: IM_com =>12volt, dummy circuit is activated Dummy injector is placed parallel with petrol injector. In Gas_mode dummy circuit activated by IM_command [cyl.1-6]. Petrol injector ground-switched by petrol ECU.

14 DI petrol injector operation Ti_idle +/- 1,0ms DI-injector signal VSI-feedback/measure signal DI injector times are ± 3 times faster compared to port injectors. Ti_idle DI ± 1,0ms Ti_max. DI ± 7ms

17 Prins AFC software Licenses Make sure you have the right software licenses: Diagnostic VSI-DI Activate VSI-DI LPG ECU VSI-2.0 DI software licenses can be installed for existing Prins accounts. Install new licenses, go to: [Info]>>[Licenses]>>[Install new licenses]>>[check online].

18 New implemented trouble codes New trouble codes are implemented in the software. Go to: [Help]>> [Trouble codes], to find the complete list of all active system trouble codes and possible diagnostic solutions.

19 Reducer/system pressure adjustment After mounting a new reducer and during maintenance always adjust the Idle pressure according target pressure! Go to: [Diagnostic]>>[Service]>>[Target pressure setting] Always adjust pressure with warm engine Correct pressure adjustment is key for optimal performance!
