GB/T 44851.18-2025 Road vehicles—Liquefied natural gas(LNG) fuel system components—Part 18:Gas temperature sensor

Scope

This document specifies the technical requirements for gas temperature sensors used in the liquefied natural gas (LNG) fuel systems of road vehicles, and describes the test methods.
This document is applicable to the vehicle types defined in GB/T 3730.1.
This document is not applicable to the following:
a) Gas cylinders;
b) Stationary gas engines;
c) Fixed components of containers;
d) Electronic fuel control systems;
e) Fuel inlets.
Components not covered by this document should be implemented in accordance with the relevant standards and undergo corresponding functional tests.
Unless otherwise specified, the pressures mentioned in this document are considered gauge pressures.
The working pressure of natural gas used as fuel in this document is set at 1.6 MPa. The pressure should be adjusted by an appropriate factor (proportion) to accommodate other working pressures. For example, a system with a working pressure of 2 MPa requires the pressure to be multiplied by 1.25.
