Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] Such as Figure 1 to Figure 8 As shown, the four-stroke linear engine of the present invention at least includes: a first piston chamber and a second piston chamber arranged coaxially in an airtight manner, a piston 8 is arranged in each piston chamber, and the left side piston chamber is divided into Left and right two combustion chambers 11,12. The right side piston divides the right side piston cavity into two left and right combustion chambers 21 , 22 . A power output shaft 9 passes through the piston cavity and is connected with two pistons; each combustion chamber is provided with a controlled electromagnetic valve 81 for controlling the intake (oil) gas and exhaust of each combustion chamber.

[0028] Among them, each piston reciprocates in the piston cavity, so that each combustion chamber performs in sequence: suction (intake) stroke, compression stro...

Abstract

The invention discloses a four-stroke linear engine. The four-stroke linear engine at least comprises a first piston cavity and a second piston cavity which are sealed and coaxially arranged, whereinpistons are arranged in the piston cavities, piston cavities are divided into left combustion chambers and right combustion chambers by the corresponding pistons, an oil outlet hole and an oil returnhole are formed in the radial surface of the piston, a piston oil outlet channel corresponding to the oil outlet hole is arranged on the piston, a piston oil return channel corresponding to the oil return hole is arranged on the piston, a shaft oil inlet channel communicating with the piston oil outlet channel and a shaft oil return channel communicating with the piston oil return channel are axially arranged in a power output shaft, and the shaft oil inlet channel and the shaft oil return channel communicate with an oil inlet and an oil outlet close to the two ends of the power output shaft.According to the four-stroke linear engine, four engines are linearly arranged on a linear shaft to sequentially execute four strokes and complete reciprocating motion, the piston is directly installed on the power output shaft, a lubricating oil path is arranged on the power output shaft, gasoline gas enters the combustion chamber, combustion is more sufficient, and the whole structure is simpleand compact, cost is low, friction is little, and efficiency is high.

Description

technical field [0001] The invention relates to a four-stroke engine, in particular to a four-stroke linear engine. Background technique [0002] The four-stroke engine belongs to the reciprocating piston internal combustion engine. The four-stroke gasoline engine completes a working cycle through four strokes of intake, compression, power, and exhaust. In this process, the piston reciprocates up and down for four strokes, and the corresponding crankshaft rotates for two weeks. The power output is completed by the rotation of the crankshaft. [0003] This structure has many inconveniences, for example: the crankshaft is a power transmission part, so its quality requirements are particularly high. Its lubrication system is inconvenient to set up, and there are many frictional contacts, which reduce the efficiency. Contents of the invention [0004] For overcoming above-mentioned defect, the object of the present invention is to provide a kind of novel four-stroke linear e...
