System qualities
Sequential injection up till 8cilinders VSI
system master-slave based Not stand-alone but
integrated In compliance with (R67.01) LPG,
(R110) CNG, CSA (North America homologation)
Head law VSI gas injector for cylinder 1 is
controlled by petrol injector 1 Respect this

LPgas tank

• Cylindrical or donut tank.
• We prefer / advise LPgas tank without the multi
  valve with big engines gt/-100kW.
• Multi valve LPgas tank
• No supply barrel reservoir, to avoid liquid
  gas to the reducer which can cause unnecessary
  tank empty situations.
• At this moment there is also no BFC tank lock
  off available in combination with a multi valve.

LPgas tank pressure

LPG vapour pressure in relation to ambient
temperature .

Brackets
Brackets are universal VSI-ecu Injector rail
(2, 3/4 5 cylinder rail) Reducer Filter unit
(old new version) Tanks (donut cylindrical)
Further can we supply dedicated kits, with
ready-made brackets and Instruction manual.

Tank lock off valve

• BFC Tank valve from engines above 300hp.
• Only official 67-R01 certified when fitted in
  combination with Stako tanks.
• Increased bore from 3.2 to 5.2mm.
• Coil is identical to standard lock off.
• Pilot operated.
• (BFC tank valve is standard on
• Prins/Stako tanks, both cylindrical and donut)
