LP Gas fuel systems for vehicle engines
|Publication Date:||12 July 2007|
This Standard specifies requirements for liquefied petroleum gas (LP Gas) fuel systems for engines mounted on motor vehicles, either for the propulsion of the vehicles or for driving some auxiliary function, for example a mixer or a pump. It provides requirements for the design and construction of component parts and for their installation in vehicles, and for tests, commissioning and periodic inspection.
This Standard does not apply to LP Gas usage such as the gas supply system for appliances in caravans, mobile homes, forklifts, floor sweepers, polishers, tow tractors, elevating work platforms and industrial engines (refer to AS 4983), or for the propulsion of marine craft (refer to AS 4732).
This Standard does not address the requirements that may apply to structural modifications carried out on the vehicle. Prior to the commencement of such work, guidance should be sought from a local Transport Authority, vehicle manufacturer or a professional engineer experienced in automotive disciplines.
