Problems solved by technology

[0002] There are various cleaning methods for the combustion chamber and intake valve of an automobile engine, including disassembly cleaning and non-disassembly cleaning. Due to the large size and complex structure of the engine, disassembly and cleaning are very troublesome. The traditional non-disassembly cleaning is directly to the combustion chamber or the intake air. Inject cleaning agent into the door cavity and soak for a long time. Since the carbon deposit in the engine is hard, adheres firmly, and is not easy to dissolve, in order to achieve the ideal cleaning effect, it is usually necessary to clean the car when it is hot, and use strong alkaline ( The cleaning agent with a pH greater than 11) will not only corrode the aluminum piston and cylinder wall of the engine, but also affect the environment or the human body, and it takes a long time to clean

Embodiment 1

[0031] A cleaning method for an engine, comprising the steps of:

[0032] S1: Remove the spark plug from the spark plug interface of the engine;

[0033] S2: Spray foam cleaner into the engine combustion chamber at the spark plug port to clean and dissolve carbon deposits;

[0034] S3: Use the suction device at the exhaust outlet to suck out the cleaning waste liquid and the fallen carbon deposit;

[0035] Specifically in step S3,

[0036] S31: Spray the mixture of non-oily detergent and water into the spark plug port for cleaning;

[0037] S32: Use an air suction device at the exhaust outlet to suck out the waste liquid and the fallen carbon deposit after cleaning in step S31;

[0038] S33: Drying the detached carbon deposits remaining in the combustion chamber with an air gun.

[0039] S4: Install the spark plug, start the engine and discharge the cleaning residue.

[0040] In this embodiment, the spark plug of the engine is removed, and then the foam cleaning agent is ...

Embodiment 2

[0051] Different from Embodiment 1, the following steps are also included before step S1:

[0052] S01: Add non-oily detergent to the engine inlet to clean the lubrication system;

[0053] S02: Start the engine at idle speed;

[0054] S03: Turn off the engine.

[0055] After the above steps, clean the engine lubrication system with a non-oily detergent. Specifically, in step S02, start the engine to run at idle speed for about 30 to 45 minutes. Non-oily cleaners can fully contact the inner wall of the lubrication system and have enough time to react with carbon deposits.

[0056] In this embodiment, after step S03, enter the cleaning step of embodiment 1, namely

[0057] S1: Remove the spark plug from the spark plug interface of the engine;

[0058] S2: Spray foam cleaner into the engine combustion chamber at the spark plug port to clean and dissolve carbon deposits;

[0059] S3: Use the suction device at the exhaust outlet to suck out the cleaning waste liquid and the fa...

Abstract

The invention discloses a method for cleaning an engine. The method for cleaning the engine includes the following steps that S1, a sparking plug is removed from a sparking plug interface of the engine; S2, foam cleaner is sprayed from the opening of the sparking plug to an engine combustion chamber to dissolve carbon deposits; S3, cleaning waste liquid and the fallen carbon deposits are sucked out from an exhaust gas emission opening by using an air suction device; S4, the sparking plug is mounted, and the engine is started to discharge cleaning residual liquid. According to the method for cleaning the engine, the carbon deposits of a lubricating system, the combustion chamber, an exhaust pipe, and a three-way catalyst are cleaned together, only the sparking plug needs to be removed, no more other components needs to be removed, efficient and fast effects are achieved, the carbon deposits in the engine is emphatically cleaned, the cleaning efficiency is high, cleaning time is short, and the cleaning effect is good.
