Description

Engine cleaning method and engine washing machine

The present invention relates to an engine cleaning method and an engine cleaning machine thereof, in particular, by repeatedly performing the steps of pouring oil, pumping oil, and filtering oil, decomposing and filtering out dirt (such as carbon deposits and sludge) in the engine. In order to restore the performance of the engine, during the process of cleaning the engine multiple times, at least the engine is stopped once to help flush away the dirt attached to the crankshaft, and the dirt can be dissolved in the oil to improve the flushing and suction of dirt. The efficiency, and the oil will be re-usable after filtration, and can extend the life of the oil.

According to the engine, when the engine is running at high speed, the oil in the crankcase is often oxidized by the high temperature. In the long run, the oil will gradually deteriorate and become coking, viscous, acidified, and then generate a large amount of scale and sludge, which is under continuous high temperature. These sludge deposits can cause clogging of the filter screen, make the camshaft and bearing lack lubrication, increase the resistance of the engine running, and seriously affect the performance of the engine. On the other hand, the fuel system of the engine is often due to incomplete combustion of the fuel and Contaminants under high temperature combustion (such as carbon monoxide, hydrocarbons and nitrogen oxides) produce carbon deposits of coke materials, which will seriously affect the performance and operation of the engine, and the carbon deposit may also follow the piston It is brought into the crankcase and attached to the inner wall of the crankcase, which will seriously reduce the heat dissipation effect of the crankcase.

There are two main methods for engine cleaning. One is to disassemble the engine one by one, and the other is to use the chemical cleaning. Because the former needs to disassemble the engine, it is not only expensive, time-consuming, but also easy to engine. The effect is that there is another way to clean the drug, but the method of cleaning the drug still has the problem of not cleaning properly and corroding the internal parts of the engine.

Other related technologies, such as the improvement of the engine lubrication system cleaning machine of the Republic of China Patent Bulletin No. M389774, mainly through the thermal decomposition of oil, sludge, and pulse pumping force generated in the engine to flush the engine interior and the lubrication system. After that, it naturally flows down from the unloading screw and flows into the oil storage tank to filter, to improve the lack of running of the dirt inside the engine, and even damage the internal oil seal of the engine.

However, there are still deficiencies in the above prior art that need to be improved. The main reasons are:

1. Conventional engine lubrication system The cleaning method of the cleaning machine has limited effect, and it is difficult to clean the sludge of the lubrication system more reliably, and the carbon deposited on the inner wall of the crankcase cannot be decomposed.

2. The known engine lubrication system cleaning machine only targets the lubrication system and cannot remove the carbon deposit of the engine fuel system (such as: combustion chamber, intake valve, fuel injector, etc.), and does not comprehensively clean the engine.

3. The engine lubrication system cleaning machine does not have other maintenance and maintenance purposes, but the engine lubrication system is not a high-frequency maintenance method. In the case of automobiles, it usually takes 20,000 to 30,000 kilometers. It is necessary to enter the repair yard for repairs, so the equipment often has the problem of being idle. This will be a waste of space and cost for the repair shop, and there is a lack of practicality of the product.

4. Conventional engine lubrication system cleaning machines cannot be adjusted according to the engine with different oil capacity. Therefore, it is difficult to shorten the cleaning time when cleaning the engine with large oil capacity.
