Escopo e aplicabilidade

This standard applies specifically to detergent additives used in both motor gasoline and ethanol motor gasoline. It is mandatory for all manufacturers producing or supplying these fuel additives for the Chinese market. The standard establishes the terminology, technical requirements, and testing methods to evaluate the cleaning performance and safety of these additives.

Requisitos técnicos

This standard strictly prohibits the intentional addition of ash-forming chemical substances into the detergent additives. It mandates that the base fuel, once mixed with the additive at the recommended dosage, must still comply with the corresponding Chinese national standards for motor gasoline. The technical requirements encompass several critical physical and chemical properties. Manufacturers must strictly control the pour point and flash point to ensure safe handling and low-temperature performance. Additionally, the standard introduces strict environmental controls by setting maximum limits for sulfur content and chlorine content. Performance-wise, the additive must demonstrate adequate anti-rust properties and demulsibility to prevent engine corrosion and phase separation. It also sets strict thresholds for nozzle mass flow loss rate and simulated intake valve deposit mass to guarantee engine cleanliness. Furthermore, the standard evaluates the real-world impact of the additive on engine hardware through limits on average intake valve deposits (IVDs) and the total combustion chamber deposit mass increase rate, utilizing specific engine bench test methods outlined in GB/T 19230.5 and GB/T 19230.6.

Métodos de ensaio

The standard mandates a series of standardized tests to verify compliance. Physical properties like flash point and pour point are evaluated using GB/T 261 and GB/T 3535 respectively. Chemical composition, specifically sulfur and chlorine content, is measured via ultraviolet fluorescence and microcoulometry methods. Performance evaluation includes rust prevention testing (GB/T 19230.1), demulsibility testing (GB/T 19230.2), and fuel injector clogging tendency tests (GB/T 19230.3). Crucially, engine bench tests are required to measure actual deposit formation on intake valves and in the combustion chamber. The standard also defines specific base fuel parameters in Appendix A to ensure consistent and comparable testing results across different laboratories.

Perguntas frequentes

What products are regulated under GB 19592-2019?

This standard regulates detergent additives specifically formulated for use in motor gasoline and ethanol motor gasoline in China.

Are there any significant updates from the previous GB 19592-2004 version?

The 2019 version introduces stricter environmental and safety parameters, including newly added limits for sulfur content and chlorine content. It also revised the flash point minimum to 60°C and the pour point maximum to -20°C, while updating various engine testing methods.

How does GB 19592-2019 differ from international ISO standards?

The standard references specific Chinese testing protocols, such as GB/T 19230.5 and GB/T 19230.6 for engine bench tests. Manufacturers must ensure their compliance testing aligns with these mandated Chinese methodologies rather than solely relying on international equivalents.
