Four-stroke engine oil path structure and four-stroke engine including structure

Abstract

The invention relates to a four-stroke engine oil path structure. The four-stroke engine oil path structure comprises an engine body, a cavity in the engine body comprises a steam cylinder cavity bodyand a cam chamber, the steam cylinder cavity body is divided into a combustion chamber and a crankcase chamber, a fuel oil inlet is formed in the crankcase chamber, a first one-way valve is arrangedon the fuel oil inlet, the cam chamber is communicated with the crankcase chamber, a second one-way valve is arranged between the cam chamber and the crankcase chamber, the cam chamber is further communicated with the combustion chamber, an inlet valve is arranged between the cam chamber and the combustion chamber, an exhaust valve is arranged on the combustion chamber, one end of the exhaust valve is communicated with the exterior of the engine body, and in addition, the invention further provides a four-stroke engine including the four-stroke engine oil path structure. According to the four-stroke engine oil path structure and the four-stroke engine including the structure, an independent engine oil box body does not need to be arranged, an independent lubricating mechanism does not needto be arranged, lubricating of all parts can be finished, in the use process of the engine, engine oil loss condition does not need to be checked, and the structure is quite convenient.

Description

technical field [0001] The invention relates to four-stroke engine technology, in particular to a four-stroke engine oil passage structure and a four-stroke engine including the structure. Background technique [0002] The four-stroke engine belongs to the reciprocating piston internal combustion engine. According to the type of fuel used, it is divided into three categories: gasoline engine, diesel engine and gas fuel engine. Piston internal combustion engines fueled by gasoline or diesel are called gasoline engines or diesel engines, respectively. Piston internal combustion engines using natural gas, liquefied petroleum gas and other gas fuels are called gas fuel engines. [0003] A four-stroke engine completes a working cycle through four strokes of intake, compression, power, and exhaust. During this process, the piston reciprocates up and down for four strokes, and the corresponding crankshaft rotates for two weeks. The four-stroke engine is a main power machine in ga...

AI Technical Summary

Problems solved by technology

[0005] Such a four-stroke engine, because the oil tank is a separate structure, the overall volume is large and the weight is heavy

At the same time, such a four-stroke engine needs to be provided with an independent lubricating mechanism. The lubricating mechanism often has a large number of parts and is very complicated, resulting in difficult maintenance and high manufacturing costs.

In addition, it is necessary to check the oil consumption of the engine regularly during use, which is very inconvenient
