Problems solved by technology

In this case, the oil supply system of the engine will not work properly
In addition, the internal pipeline is also prone to rust due to long-term exposure to humid air
According to actual use experience, if the aviation piston engine is parked for more than 1 month without oil seal treatment, the carburetor will not work normally

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The invention provides an aviation piston engine oil sealing device and an oil sealing method using the device. Through the mixed oil seal oil of lubricating oil and gasoline in a certain ratio, the oil seal device and the corresponding oil seal method, the internal air passage of the engine and the carburetor are well protected by oil seals.

[0024] Aviation piston engine oil seal device described in the present invention is as figure 1 , the oil seal device includes an oil seal oil tank 1, a storage battery 3, a fuel pump 6, an oil return line 7, and an oil supply line 8, wherein the oil tank 1 is provided with a liquid level gauge 4, a refueling port 5, an oil outlet 10 and Oil return port 11. One end of the oil return line 7 and the oil supply line 8 are respectively connected to the oil return port 11 and the oil outlet 10 of the oil tank 1, an...

Abstract

The invention discloses an aviation piston engine oil-sealing arrangement and an oil-sealing method; wherein, the oil-sealing arrangement mainly consists of an oil-sealing cylinder, a battery, a fuel pump, a scavenge oil pipeline and an oil supply pipeline and can supply oil-sealing oil to the engine. The oil-sealing method achieves the oil-sealing of the engine under the situation of not dismounting the pipelines and a carburetor by the four steps of adding oil through the oil cylinder, connecting the pipelines, draining the air in the pipelines, starting the engine, starting oil-sealing and feeding oil by cold rotating; oil-sealing arrangement can be applied to a four-stroke piston engine; the oil-sealing device has simple structure and convenient operation.

Description

technical field [0001] The invention belongs to the technical field of aero-engines, and relates to an aero-engine oil seal technology, in particular to an oil sealing device and an oil sealing method applied to a piston engine in an aeronautical system. Background technique [0002] The working principle of the aviation piston engine is the same as that of the ground vehicle internal combustion engine. After the fuel is burned in the cylinder, the piston is pushed to do work. The aviation piston engine works according to the characteristics of the propeller, and the fuel is usually gasoline. [0003] When the piston engine is working, gasoline fuel is sprayed into the air passage in the carburetor to form a mixture of oil and gas. The oil-air mixture enters the engine cylinder during the engine working cycle, and is discharged from the engine after compression and combustion. The air passage and carburetor of the engine are connected to the air. If the engine is parked in ...
