An operation and maintenance method for an atomized internal combustion engine fuel injection system

Abstract

The invention provides an operation and maintenance method for an atomization type oil injection system of an internal combustion engine. An electromagnetic valve comprises a valve body, an injectioncylinder, an extension part, injection holes, a bump, a valve clack, a pressure relief passage, a joint, saw-toothed parts, electromagnetic coils, a bracket, an external extension terminal, a detection passage, an oil cylinder, an oil feeding passage, an oil feeding pipe, a coil housing, a valve rod inner hole, a guide sleeve, a valve rod, a steel ball, a joint passage, a shrinkage part, a piston,a piston upper hole, a piston left hole, a piston right hole, a choke plug, first springs, L-shaped seats, second springs, a combustion chamber, a coarse filter and a fine filter. In selection of pressure oil before the oil injection system is put into storage, different types of pressure oil is selected according to the temperature of the season; No.-10 oil is used in winter; No.0 or No.10 oil is used in summer; the coarse filter is periodically replaced every two years; the fine filter is periodically replaced every year; the electromagnetic valve is dismounted every half a year; the combustion chamber is washed; an oil guide groove and the valve rod inner hole are washed; whether the sealing ring has indentation or scratches or not is checked; the sealing ring should be repaired if thesealing ring has indentation or scratches; and the sealing ring should be replaced if the sealing ring has abrasion.

Description

technical field [0001] The invention relates to the related field of internal combustion engine fuel injection systems, in particular to an operation and maintenance method of an atomized internal combustion engine fuel injection system. Background technique [0002] Internal combustion engines are widely used in the existing technology, such as transportation, large-scale equipment operation and other fields are widely used, which will be applied to the fuel injection system, the fuel injection system sends oil to the into the combustion chamber for combustion. [0003] In actual use, the existing fuel injection system has the following problems: [0004] 1. During the injection process, it is inevitable that uneven injection will lead to insufficient combustion. In this regard, some existing technologies adopt the atomization method.

AI Technical Summary

Problems solved by technology

[0004] 1. During the injection process, it is inevitable that uneven injection will lead to insufficient combustion. In this regard, some existing technologies adopt the atomization method. However, the atomization structure in the prior art is often complicated and the cost is high. , such as using parts such as heat exchangers for atomization, the installation structure of the heat exchanger is relatively complicated, and there are many restrictions on the use

[0005] 2. In the prior art solenoid valve, due to blockage or pressure fluctuation, the oil chamber is over-pressurized, and sometimes the pressure cannot be released in time

[0006] 3. There is a need to clean the oil cavity in the prior art, but it is difficult to clean it during operation and maintenance

[0007] 4. In the prior art solenoid valve, when the oil supply pressure is large due to the oil supply deviation, water hammer is prone to occur

[0008] 5. The electromagnetic coil structure in the prior art is difficult to take into account the problems of firmness, large magnetic flux and material saving at the same time

[0009] 6. The operation and maintenance of the fuel injection system and its solenoid valve in the existing technology is not effective, and it is difficult to maintain a long service life
