Abstract
Description
Technical Field
[0001] The utility model relates to a universal power machinery maintenance system, in particular to a universal gasoline and diesel engine maintenance system. Background Art
[0002] Engine oil has the functions of lubrication, sealing, cooling, cleaning and anti-oxidation in the engine. It can not only reduce friction and wear and extend the life of the engine, but also maintain the normal operating temperature of the engine, clean the internal parts of the engine, and prevent the oil from oxidation and deterioration. Therefore, it is very important to change the oil regularly and ensure that the oil suitable for the engine is selected.
[0003] Currently, during the oil change process, maintenance personnel manually change the oil, resulting in over-oil or under-oil filling, or failure to drain out the old oil and only adding a small amount of new oil.
[0004] Too much oil will increase the liquid friction inside the engine, causing increased engine power consumption and reduced fuel economy. At the same time, too much oil may leak into the cylinder, affecting combustion efficiency, causing problems such as abnormal exhaust odor and excessive exhaust emissions.
[0005] Too little oil cannot effectively lubricate the metal parts inside the engine, increasing friction and wear, shortening the engine life. At the same time, too little oil cannot effectively cool the engine, causing the engine temperature to rise, which may cause overheating problems and even cause engine failure.
[0006] If you simply top up the engine oil instead of changing it regularly, it will have some negative effects on engine performance:
[0007] (1) Reduced oil quality: Oil will gradually become contaminated and aged during use, losing its lubricating, cooling and cleaning functions. If you simply add oil without replacing it, the quality of the oil will gradually decline and will not provide adequate protection and performance.
[0008] (2) Increased engine wear: Aging engine oil may form carbon deposits and sediments, which can clog the oil filter and oil passages, causing poor oil flow and increasing friction and wear between engine components.
[0009] (3) Reduce engine life: The main function of engine oil is to reduce friction and wear between engine components and extend engine life. If the quality of engine oil decreases or the oil does not flow smoothly, engine components are easily damaged, resulting in a shortened engine life.
[0010] (4) Impact on engine performance and fuel economy: The decline in engine oil performance will lead to increased friction, increased engine power consumption, and reduced fuel economy. At the same time, there may be too many pollutants in the engine oil, which will have an adverse effect on the engine's combustion efficiency and emission performance. Therefore, it is very important to change the engine oil regularly. Simply replenishing the engine oil without changing it cannot guarantee the quality and performance of the engine oil, and may have an adverse effect on the life and performance of the engine.
[0011] To sum up, too much, too little or deteriorated engine oil will seriously affect the normal performance of the engine and greatly increase engine failures. Therefore, regularly changing the engine oil and ensuring the engine has an appropriate amount of oil are the core tasks of engine maintenance. Summary of the invention

[0014] Furthermore, one end of the waste oil inlet pipe is connected to the oil drain connector of the gasoline and diesel engines, and the other end is connected to the oil inlet of the oil extraction diaphragm pump.
[0015] Furthermore, one end of the waste oil outlet pipe is connected to the oil outlet of the oil extraction diaphragm pump, and the other end is connected to the recovered oil back-pull barb connector on the waste oil tank.
[0016] Furthermore, the oil filling port connector is installed at the oil dipstick position of the gasoline and diesel engines by means of a threaded connection.

[0018] Furthermore, the oil drain port connector is installed at the oil drain screw position of the gasoline and diesel engines by means of a threaded connection.
[0019] Furthermore, the position of the oil discharge port connector is lower than the position of the oil recovery back-pulling barb connector in the vertical direction.
