Cleaning method and device for engine

Abstract

The invention discloses a cleaning method and device for an engine. The cleaning method comprises the steps for cleaning a combustion chamber of the engine, specifically, an appropriate number of cleaning agents are added into the combustion chamber; ultrasonic waves are transmitted to the cleaning agents through an energy-concentrating-type ultrasonic amplitude transformer, so that the cleaning agents vibrate, and then carbon deposits on the inner wall of the combustion chamber fall off; the cleaning agents and the fallen-off carbon deposits are sucked out of the combustion chamber through amaterial suction pipe; and the fallen-off carbon deposits remaining in the combustion chamber are blown out through a blower gun, and the combustion chamber is blow-dried. The invention further discloses the ultrasonic cleaning device for the engine. The ultrasonic cleaning device comprises the energy-concentrating-type ultrasonic amplitude transformer matched with the combustion chamber of the engine and provided with a specific structure. According to the technical scheme, the cleaning agents do not need to be heated up and do not need have the high PH value, then the car engine can be effectively cleaned, and corrosion of cleaning liquid to the car engine can further be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of engine cleaning, in particular to an engine cleaning method and a cleaning device. Background technique [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 usually needs to be cleaned when the car is hot, and strong alkaline is required. (PH value greater than 11) cleaning agent will not only corrode the aluminum piston and cylinder wall of the engine, but also affect the envir...

[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 usually needs to be cleaned when the car is hot, and strong alkaline is required. (PH value greater than 11) will not only corrode the aluminum piston and cylinder wall of the engine, but also affect the environment or human body, and it takes a long time to clean

[0003] Ultrasonic cleaning technology has been widely used in the industrial field at present, but due to the limitation of equipment (the existing ultrasonic cleaning equipment is mostly a cleaning tank structure, an ultrasonic transducer is installed at the bottom of the cleaning tank to convert the electric power generated by the ultrasonic frequency power supply into mechanical vibration and The wall of the cleaning tank radiates ultrasonic waves to the cleaning liquid in the tank) and the particularity of the engine structure, it has not been effectively applied to the cleaning field of the engine, although the prior art also proposes some technical solutions for ultrasonic cleaning for auto parts cleaning , but there are certain technical defects, and the effect of using it for engine cleaning is not ideal. For example, the patent CN101768749A discloses a carbon deposition cleaning method for high-pressure turbine blades of an engine. It is to disassemble the blades and immerse them in an ultrasonic cleaning tank for cleaning. It belongs to disassembly and cleaning, which is very troublesome; patents CN102107200A and CN201751552U directly fix the ultrasonic vibrator (transducer) on the outside of the component to be cleaned, so that the ultrasonic signal is transmitted to the cleaning solution in the inner cavity through the outer wall of the component, which is low The energy density ultrasonic cleaning method is only suitable for the cleaning of small pipelines, and the combustion chamber of the engine has a large volume and a thick wall, so it is difficult to meet the cleaning requirements with this cleaning method
