Introduction

Gasoline detergents are added to gasoline or ethanol gasoline to inhibit or clean the engine's intake system, fuel supply system, and... (or) substances deposited in the combustion chamber. To scientifically evaluate the effectiveness of gasoline detergents, it is necessary to establish unified standard testing methods for scientific quantification. This document describes the various performance characteristics of gasoline detergents. It is divided into five parts, addressing the different functional properties of gasoline detergents and outlining differentiated test methods. The law establishes a comprehensive, hierarchical, and scientifically rigorous evaluation system. GB/T 19230 is proposed to consist of five parts. ---Evaluation of the effectiveness of gasoline detergents, Part 1.Determination of rust-preventive performance. The purpose is to evaluate the rust-preventive properties of gasoline detergents. Performance, ensuring that the addition of gasoline detergents will not reduce the rust-preventive properties of automotive gasoline or automotive ethanol gasoline. ---Evaluation of the effectiveness of gasoline detergents, Part 2.Determination of demulsification performance. The purpose is to evaluate the demulsification performance of gasoline detergents. Performance ensures that the addition of gasoline detergent does not affect oil-water separation ability, avoiding the risk of corrosion and blockage caused by emulsification. ---Test Methods for Evaluating the Effectiveness of Gasoline Detergents - Part 3.Effect of Gasoline Detergents on Clogged Electronic Orifice Fuel Injectors (PFI) Test methods for evaluating the effect of gasoline detergents on the clogging tendency of electronic fuel injectors. The aim is to assess the impact of gasoline detergents on the clogging tendency of electronic fuel injectors. To ensure the stability of the engine fuel supply system. ---Test Methods for Evaluating the Effectiveness of Gasoline Detergents - Part 5.Effects of Gasoline Detergents on Deposits in Gasoline Engine Intake Valves and Combustion Chambers A bench test method for evaluating the influence of pollutant generation tendency on engine performance (Ford 2.3L method). The aim is to evaluate the impact of pollutant generation tendency on engine performance using the Ford 2.3L method. The ability of gasoline detergents to inhibit the formation of deposits in the intake valve and combustion chamber is a testament to the core function of gasoline detergents. ---Test methods for evaluating the effectiveness of gasoline detergents, Part 6.Effects of gasoline detergents on deposits in gasoline engine intake valves and combustion chambers Engine bench test method (M111 method) for evaluating the influence of detergent generation tendency. The purpose is to evaluate gasoline detergents using the M111 method. The ability to suppress the formation of deposits in the intake valve and combustion chamber is a testament to the core function of gasoline detergents. Evaluation of the effectiveness of gasoline detergent Part 1.Determination of Rust Inhibition Performance Warning---Personnel using this document should have practical experience in formal laboratory work. The use of this document may involve certain hazardous activities. This document does not address all potential safety issues related to the materials, equipment, and operations used. Users are responsible for taking appropriate safety and health precautions. Implement the measures and ensure they comply with the conditions stipulated by relevant national laws and regulations.
