No component of the CNG-system shall be located within 100 mm of the exhaust or similar heat source, unless such components are adequately shielded against heat. The pressure may not be adjusted and is fixed on 3.3 bar Copyright © Prins Autogassystemen B.V. 2013 Page 8... -
Page 10: The Injector Rail
The injector rail VSI 4-cylinder injector rail [KN8/KN9] The Prins injector rail is available in 2 - 3 - 4 - 5 rail versions. Guideline VSI injector choice : divide total engine power in kW up into the amount of cylinders. -
Page 11: The Prins Filter Unit
The Prins filter unit The filter unit filters the LPG/CNG and is also used to measure the gas temperature (T_gas) and gas pressure (Psys) in the VSI system, by means of a combination sensor. The filter unit has a single or a double outlet of 11mm. -
Page 12: The Vsi Computer
The VSI computer can be mounted into the engine room as well as inside the car, depending on the converted vehicle. Never mount the computer near a heat source. Never mount the computer upside down. Never clean engine room with a high pressure cleaner. VSI-I Copyright © Prins Autogassystemen B.V. 2013 Page 11... -

Page 77: Checklist After Installation
Checklist after installation Connect the serial interface cable and run the VSI diagnosis program. Install the VSI main fuse, and program the fuel switch. Turn the ignition key in the accessory position. When working on the car, beware of moving and rotating parts in the engine compartment. When commissioning the LPG/CNG system, you must activate the VSI computer with the diagnosis software.
