Scope: This standard specifies the technical requirements for the whole vehicle before the installation of natural gas vehicle-specific devices on used gasoline vehicles, the technical requirements for installation, the technical requirements for the whole vehicle after installation, inspection methods, marking, accompanying technical documents, and the quality assurance period. This standard applies to used gasoline vehicles registered in Sichuan Province that are equipped with compressed natural gas vehicle-specific devices with a rated working pressure of 20MPa; Main technical content: To further standardize the modification behavior and technical requirements of various modification enterprises, make them more guiding, more operable, and more effectively improve the modification quality of natural gas vehicles. Establishing a local natural gas vehicle industry standard system is of great significance for ensuring the safe, stable, healthy, and orderly development of natural gas vehicles in our province. Through amendment, this standard sets requirements for the technical conditions of the whole vehicle before the installation of natural gas vehicle-specific devices, the technical requirements for installation, and the technical requirements for the whole vehicle after installation, as well as inspection methods, etc. The aim is to: 1. Standardize and unify the performance and configuration of vehicles after the installation of natural gas-specific devices, which is conducive to the safe operation of gasoline vehicles equipped with natural gas vehicle-specific devices; 2. Form a standardized normative system of configuration series with standards such as GB 19239-2022 "Installation Code for Gas System of Gas Vehicles", DB51/T 2146 "Specification for Natural Gas Vehicle Modification Enterprises", and DB51/T 929 "Inspection Code for Used Vehicles Compressed Natural Gas-Specific Devices", so as to better guide enterprises in production and users in use.
