A kind of diesel engine injector cleaning agent and preparation method thereof

Abstract

The invention discloses a cleaning agent for an oil nozzle of a diesel engine. The cleaning agent comprises the following components in parts by mass: 26.8 to 27.3 parts of sodium dodecyl benzene sulfonate, 10.9 to 13.1 parts of glycerin monostearate, 7.3 to 9.5 parts of sodium silicate, 6.6 to 8.7 parts of lauroyl diethanolamide, 2.6 to 3.5 parts of benzotriazole, 23.5 to 25.8 parts of a surfactant, 9.5 to 13.3 parts of diethanol amine and 5.4 to 7.9 parts of ethyl alcohol. According to the cleaning agent, a modern scientific and technological biotechnology is adopted, and the cleaning agent is prepared from sodium dodecyl benzene sulfonate, glycerin monostearate, sodium silicate, lauroyl diethanolamide, benzotriazole, the surfactant, diethanol amine and ethyl alcohol; the selected raw materials are scientifically batched and are subjected to the procedures such as stirring, pressurization and heating, distillation and centrifugation; the processed cleaning agent has a good cleaning effect on the oil nozzle, and can clean carbon black layers forming on the surfaces of a cylinder and a piston after coking; a protective layer can be formed on the metal surface; and the cleaning agent is non-corrosive, environment-friendly and nontoxic to use, and is low in cost.

Description

technical field [0001] The invention belongs to the technical field of cleaning agents, and in particular relates to a cleaning agent for a fuel injector of a diesel engine and a preparation method thereof. Background technique [0002] The advantages of a diesel engine are high power and good economic performance. The working process of a diesel engine is four strokes of intake, compression, work, and exhaust. When working, the air enters the cylinder, and the piston moves up and down in the cylinder. The air is compressed to At the limit, the temperature can reach 500-700°C and the pressure can reach 40-50 atmospheres. When the piston is close to the top dead center, the high-pressure pump on the engine injects diesel into the cylinder at high pressure through the injector, and the diesel forms fine oil particles. , expands violently in a high-pressure and high-temperature environment, generating explosive force and pushing the piston down to do work. At this time, the tem...

[0002] The advantages of a diesel engine are high power and good economic performance. The working process of a diesel engine is four strokes of intake, compression, work, and exhaust. When working, the air enters the cylinder, and the piston moves up and down in the cylinder. The air is compressed to At the limit, the temperature can reach 500-700°C and the pressure can reach 40-50 atmospheres. When the piston is close to the top dead center, the high-pressure pump on the engine injects diesel into the cylinder at high pressure through the injector, and the diesel forms fine oil particles. , expands violently in a high-pressure and high-temperature environment, generating explosive force and pushing the piston down to do work. At this time, the temperature can reach 1900-2000°C, the pressure can reach 60-100 atmospheres, and the power generated is very large, so diesel engines are widely used In large diesel vehicles, the mixed gas in the cylinder of the diesel engine is compression-ignited instead of ignited. In the actual work process, due to various reasons, the combustion of diesel oil will be insufficient, and a large amount of exhaust gas will be produced. The exhaust gas contains a large amount of Carbon black and harmful gases, carbon black will block the fuel injector nozzle of the diesel engine injector, thereby deteriorating combustion, forming a vicious circle, not only increasing fuel consumption, but also emitting more exhaust gas, polluting the environment
