What is ISO 20766‑20 - Filter unit of LPG fuel systems about?
ISO 20766 is a series of international standards on road vehicles that specifies general information regarding the filter unit component of liquefied petroleum gas fuel, intended for use on the types of motor vehicles.
ISO 20766‑20 is the 20th part of the ISO 20766 series of documents that provides general design principles and specifies requirements for instructions and marking.
ISO 20766‑20 also specifies test requirements for filter units.
NOTE 1: ISO 20766‑20 is applicable to vehicles (mono-fuel, bi-fuel or dual-fuel applications) using gaseous fuels in accordance with ISO 9162.
NOTE 2: ISO 20766‑20 is not applicable to the following:
- Fuel containers
- Stationary gas engines
- Container mounting hardware
- Electronic fuel management
- Refuelling receptacles.
Who is ISO 20766‑20 - Filter unit of LPG fuel systems for?
ISO 20766‑20 on LPG fuel systems is useful for:
- Manufacturers of LPG fuel vehicles
- Road vehicle engineers
- Mechanical engineers
- LPG suppliers
Why should you use ISO 20766‑20 - Filter unit of LPG fuel systems?
A filter unit of LPG fuel systems is necessary to protect the injectors and to ensure proper operation of the entire system.
ISO 20766‑20 gives marking guidelines so that the users and manufacturer can trace the product in accordance with working pressure and temperature range, the direction of flow (when necessary for correct installation), the flow capacity, type of fuel, and electrical ratings.
ISO 20766‑20 navigates you through the requirements on the construction and assembly of the filter units.
ISO 20766‑20 describes the test methods for filter units and guides manufacturers with tools to improve their products by outlining tests that protect the device ensuring hydrostatic strength and low and high temperature of the LPG filter unit.
Moreover, ISO 20766‑20 could assist you with the designing and manufacturing of filter unit components that act as a permeable barrier that cleans the fuel of impurities, sediment, contaminants, and rust for proper engine performance. In this manner, you can get relatively low-cost filter units, which will guarantee you greater travel safety and longer life for both the installation and the engine. With obedience and compliance to ISO 20766‑20, you can achieve precision in terms of product functionality.
