liter liquid gas depending on the size  The storage pressure is approximately bar  At an excess pressure of approx 25-30 bar the safety valve opens and blowes out the gas outof-doors  Recess tanks as usual today, which are available in different sizes can be placed directly in the spare-wheele recess of the trunk  The spare wheel will be replaced by emergency tire inflator Automotive

safety valve opens and blowes out the gas out-of-doors, so the tank can not explode at a fire of the vehicle!  Also when refueling the savety valve cuts off when the recess tank is (at approx 80%) full  At the same unit there is a tank fuel level indicator and a manual shut-off valve in order not to drain the complete tank at the gas system when performing repairs  The solenoid shut-off valve is only activated after the activation of gas operation Automotive Aftermarket 14 Confidential | AA/MKC | 23-25/04/2008 | © Robert Bosch GmbH 2008 All rights reserved, also regarding any disposal,

regulator Tasks / Functions  The liquid gas arrives from the tank to the evaporator pressure regulator  Via the cooling circuit the evaporator pressure regulator is heated in order to guarantee a faster vaporisation of the liquid gas  At the evaporator the pressure is reduced to bar This pressure is constantly available at the injectors Automotive Aftermarket 15 Confidential | AA/MKC |
