Problems solved by technology

[0002] At present, cars with electronically controlled fuel supply systems have replaced cars with mechanical fuel supply systems for carburetors. The fuel injectors of this type of engine have small apertures and high operating temperatures, which are easily blocked by carbon deposits and cause fog. Poor gasification, poor fuel supply, fuel consumption, substandard emissions, etc. During long-term use, the sealing surface of the intake valve of the EFI engine is also prone to carbon deposits, resulting in poor sealing of the cylinder, resulting in reduced engine power and no gas outside. leakage, which will seriously affect the fuel economy, power output and exhaust emission indicators, making the performance of the engine degrade

Abstract

A composite cleaner for gasoline contains polyisobuteneamine, more than one polyether with alkylphenol and / or dihydroxy and more than two polyoxyvinyl ethers in weight ratio of (44-54):(12-22):(39-49). It can remove the oil mud and colloidal deposit in fuel oil system of engine, improve performance of engine, and decrease consumption of fuel.

Description

Technical field [0001] The invention relates to a gasoline detergent composition, which is added to vehicle gasoline to effectively remove or inhibit the formation of carbon deposits formed in the fuel system of the automobile engine. Background technique: [0002] At present, cars with electronically controlled fuel supply systems have replaced cars with mechanical fuel supply systems with carburetors. The fuel injectors of this engine have a small diameter and high operating temperature, which can easily be blocked by carbon deposits and cause fog. Poor chemical conversion, poor fuel supply, fuel consumption, substandard emissions, etc., in long-term use, the sealing surface of the intake valve of the EFI engine is also prone to form carbon deposits, resulting in inadequate cylinder sealing, resulting in reduced engine power and no gas. Leakage seriously affects fuel economy, power output and exhaust emissions indicators, and makes the performance of the engine drop. Summary o...
