Rev 3 of 2009 09 22 PROCEDURES FOR FUEL SELECTION The automatic or commanded procedures for selecting the engine fuel are described below The LPG petrol or petrol LPG changeovers can occur in controlled way by the user or automatically by the LPG ECU LPG electronic control unit 7 2 1 CHANGEOVER FROM PETROL TO LPG AUTOMATIC CHANGEOVER TO LPG The system memorises the last fuel mode set when the engine was switched off and proposes it on the next start up Take note when starting the vehicle after switching off the engine in LPG mode the engine nevertheless starts in the petrol mode as shown in Fig 7 2 1 2 and then automatically changes over to LPG as shown in Fig 7 2 1 3 If the temperature of the vaporiser is higher or equal to the temperature of petrol LPG changeover the changeover to LPG occurs after a few seconds Fig 7 2 1 3 However if the vaporiser temperature is lower than that of the petrol LPG changeover the engine continues to function temporarily in the petrol mode as shown in Fig 7 2 1 2 until the vaporiser reaches the changeover temperature The changeover to LPG occurs once this temperature has been reached Fig 7 2 1 3 The lower the temperature of the vaporiser in respect to that of the petrol LPG changeover the longer the time interval Page 11 of 21 LPG CONTROLLED CHANGEOVER If the engine is permanently fuelled by petrol display Fig 7 2 1 1 the changeover to LPG must be commanded b

5. The volume of liquid LPG tends to increase with the temperature If the tank was filled at 10096 following an increase in the temperature the volume of liquid LPG would increase with the consequent increase of pressure The limiting at 8096 of the filling stops this from happening In any case if the pressure in the tank should exceed 27 bar the pressure relief valve would intervene to restore the safety conditions 6 4 THERMAL FUSE Safety device located on the tank If the car is involved in a fire this device is activated and eliminates the risk of explosion of the tank Some types of tanks do not come with a thermal fuse For these tanks a suitably dimensioned pressure relief valve has the same safety function as the thermal fuse 6 5 PRESSURE RELIEF VALVE Safety device located on the tank that is activated if the pressure inside the tank exceeds 27 bar The activation causes a temporary and controlled discharge of LPG which only lasts for the time needed for the pressure value inside the tank to fall below the threshold value Page 9 of 21 7 USE OF THE SYSTEM The LPG Polaris system is activated deactivated by simply pressing the special switch located on the changeover panel The changeover switch mainly allows choosing to supply the engine with petrol or gas and therefore to execute the switch between the two fuel systems from gas to petrol or from petrol to gas To use the changeover switch simply press the chang

G electronic injection in gaseous phase thus also allowing the phased sequential electronic injection of the LPG in the gaseous phase in spark ignition engines In the master slave functioning the LPG control unit slave processes the injection signals coming from the original petrol control unit master of the vehicle and commands the functioning of the LPG injectors As a result the functioning strategy of the LPG fuel supply imitates the strategy of the petrol functioning phased sequential semi sequential full group etc This functioning strategy is made possible by the LPG electro injectors which can have opening closing times the same as those of the corresponding petrol injectors STARGAS S r l POZZUOLI NA ITALY Rev 3 of 2009 09 22 Page 4 of 21 5 GENERAL DESCRIPTION OF SYSTEM PARTS STARGAS S r l POZZUOLI NA ITALY LEGEND OF MAIN COMPONENTS OF THE POLARIS LPG SYSTEM POS DESCRIPTION ELECTRONIC CONTROL UNIT ENGINE COMPARTMENT LPG SOLENOID VALVE TYPE C HERCULES VAPORISER GASIFIER VAPORISER WATER HEATING TUBES GASEOUS PHASE LPG FILTER oal S Wi N gt GASEOUS LPG FEEDING TUBE TO ELECTRO INJECTORS LOW PRESSURE N ELECTRO INJECTORS LPG FEEDING TUBE TO VAPORISER HIGH PRESSURE FILLING UNIT 10 FUEL TANK 11 CHANGEOVER SWITCH 12 MULTI VALVE Rev 3 of 2009 09 22 Page 5 of 21 HERCULES VAP

This leads to a substantial reduction in the useless and often unnecessary enrichment of the mixture The master slave functioning includes the cut off phases of the fuel supply with subsequent interruption of the LPG flow This guarantees a significant reduction in LPG consumption in respect to older retrofit systems However this LPG consumption in litres km is always higher than the corresponding petrol consumption since the calorific power of the LPG is lower than that of petrol This higher consumption in respect to the petrol consumption percentage varies based on the LPG composition distributed and can be estimated indicatively at no higher than 2096 any case the use of the Pol ris system leads to a considerable saving on fuel costs due to the lower cost of LPG compared to petrol 2 AIM AND CONTENTS STARGAS S r l POZZUOLI NA ITALY Rev 3 of 2009 09 22 This manual aims at providing the end user with general information and descriptions on the use maintenance and guarantee of the Pol ris LPG system installed on the vehicle For a correct use of the LPG system and to maintain the reliability and efficiency of the vehicle over time the user must remember and respect the information recommendations reported in this manual This manual must be kept in a safe place by the user for future reference It must be used for the correct use of the guarantee offered on the products For this reason it contains the eq
