Description
Technical Field
The invention belongs to the technical field of automobile maintenance, relates to a cylinder opening-free quick cleaning process for an engine, and particularly relates to a cylinder opening-free quick cleaning process for deposited carbon in an engine combustion chamber.
Background
It is well known in the art that as the mileage of an automobile increases, deposits and carbon deposits form in the engine combustion chamber. Practice shows that a small amount of carbon deposition is helpful for improving the power and fuel economy of an engine, but a large amount of carbon deposition can greatly influence the performance of the engine, so that the power and fuel economy are seriously reduced, hydrocarbon HC and nitrogen oxide NOx in exhaust emission are seriously deteriorated, carbon deposition knocking interference can be generated, and the cold starting performance of the engine is deteriorated. Therefore, the deposited carbon in the combustion chamber must be removed in time after reaching a certain degree.
In order to avoid serious carbon deposition, various fuel additives are developed. After the automobile runs for a certain distance, some detergent additives can be added into the fuel oil, so that the whole box of fuel oil becomes a detergent with mild medicine property, and carbon deposition is controlled to be further generated while the automobile runs. However, since the detergent is added at a low concentration, this cleaning does not work at all once the combustion chamber is coked to a severe extent. If the detergent concentration is increased, engine bench test results show that this will seriously affect the dynamic properties of the engine.
Therefore, for a long time, the engine with serious deposit carbon deposition in the combustion chamber can only be cleaned by manual cleaning. The common practice is: the engine is detached from the automobile, a cylinder cover is opened, an air valve, a piston ring and the like are taken down, parts of a combustion chamber including the cylinder cover are cleaned by trichloroethylene or a carbon removing agent, and sticky substance components such as colloid, asphaltene and the like in carbon deposition are removed; then the carbon compound is moved into gasoline or hot water to be washed by a brush to remove the residual carbon compound, metal oxide and the like, and finally the carbon compound, the metal oxide and the like are washed by 0.1 to 0.3 percent of potassium chromate solution to be dried. After checking that each part is normally reloaded with the engine, the automobile is returned. Then the automobile needs to go through a period of running-in of the engine to recover the original service performance.
Obviously, the manual cleaning method not only wastes time and labor and is low in efficiency, but also greatly damages the engine and greatly shortens the design life of the engine. Moreover, the combustion chamber is often cleaned too cleanly, but the sealing performance of the combustion chamber is reduced, so that the power performance of the engine is reduced, and the use performance of the whole vehicle is finally influenced.

The fuel detergent adopted by the invention has the characteristic of mild drug property, so that the fuel detergent hardly causes damage to parts of an engine after being used.
As shown in fig. 3, the additive gasoline tank according to the present invention is structurally characterized in that an electric fuel pump 2 and a power supply lead-out wire thereof are disposed in a tank body 1 of the additive gasoline tank, an inlet end of the electric fuel pump 2 is provided with a fuel pump filter 21, and an outlet end of the electric fuel pump 2 is connected to a fuel filter 7; the upper surface of the box body 1 is respectively provided with an electric fuel pump power supply connecting wire 11, a fuel detergent and gasoline injection port 12 and a gasoline additive outlet 13; the oil outlet 13 is connected with an oil outlet hose 3 which is connected with an outlet of the fuel filter 7, the tail end of the oil outlet hose 3 is connected with a quick connector 4, and the quick connector 4 is hermetically connected with an oil pressure detection hole 51a of a fuel main pipe of the cleaned engine 5;
when in operation, the cleaned engine 5 is started first, then the electric fuel pump 2 in the gasoline tank body 1 of the additive agent is started, and the original vehicle gasoline and the additive agent gasoline are supplied to the engine 5 at the same time; placing a vehicle transmission where a cleaned engine 5 is located at a first gear, braking a vehicle running system, combining a clutch, and gradually increasing the accelerator opening of the vehicle to a medium-load working condition of the engine; after the engine runs stably, the supply of the original vehicle gasoline is cut off (namely, the power supply of the original vehicle fuel pump is cut off), and the additive gasoline Y is used for supplying oil independently; then gradually increasing the opening degree of the accelerator until the large-load working condition is entered; when the cleaned engine 5 is burning to do work, the deposited carbon in the combustion chamber is quickly decomposed, and is discharged out of the cylinder along with the exhaust gas after being burned and gasified.

With regard to the arrangement of the oil pressure regulator involved in the process of the present invention, there are generally the following two cases. One situation is: the oil pressure regulator 53 is directly mounted on the fuel manifold 51 of the engine 5 to be cleaned, and the fuel tank and the connection mode thereof shown in fig. 1 are adopted; the other situation is that: the cleaned engine fuel manifold 51 is not provided with an oil pressure regulator, and in this case, an oil pressure regulator 6 is additionally provided in the additive gasoline tank 2 and is positioned between the outlet of the fuel filter 7 and the oil outlet hose 3, as shown in fig. 2.

The invention discloses a process for removing carbon deposit in an engine combustion chamber, which mainly comprises the following steps:
