Problems solved by technology

Although this has played a lubricating effect, in the structure where the air passage of the two-stroke engine is arranged on the side wall of the cylinder, the machine oil will enter the combustion chamber with the air flow, and the combustion of the machine oil in the combustion chamber is insufficient. Reduce the emission performance of the two-stroke engine, produce excessive harmful emissions, pollute the environment, or the engine oil will directly enter the exhaust passage, and be discharged into the atmosphere with the engine exhaust gas, causing more serious environmental pollution
In a traditional four-stroke engine, since the intake and exhaust valves are all set on the cylinder head, no matter whether the multi-valve technology or the traditional single-valve technology is adopted, the size of the intake and exhaust valves is limited by the cross-sectional area of ​​the cylinder. Affect the intake and exhaust area of ​​the intake and exhaust valves, making the intake and exhaust efficiency low

Embodiment 1

[0052] Such as figure 1 The shown right-angle gas distribution suspension piston engine includes a cylinder 1 and a piston 2, and the piston 2 is fully or partially arranged in the cylinder 1, and the cylinder top dead center 121 on the cylinder 1 corresponding to the piston top dead center of the piston 2 and the The piston 2 and the cylinder 1 are suspended or quasi-suspended within the entire stroke range or part of the stroke range between the cylinder bottom dead center 122 on the cylinder 1 corresponding to the piston bottom dead center of the piston 2, and the piston 2 is suspended or quasi-suspended. A lower side wall air distribution passage 5001 is provided on the side wall of the cylinder 1 constituting the quasi-floating setting relationship, and a lower side wall air distribution seat is provided on the side wall of the cylinder 1 in each lower side wall air distribution passage 5001 4. A lower side wall gas distribution valve body 5 is set at each lower side wall...

Embodiment 2

[0055] Such as figure 2 The difference between the shown right-angle air distribution suspension piston engine and Embodiment 1 is that the right-angle air distribution suspension piston engine is a four-stroke engine, and the lower side wall air distribution channel 5001 is located in a suspension setting or quasi-suspension setting relationship with the piston 2. Cylinder 1 constitutes the area at the top dead center 121 of the cylinder or on the side wall near the top dead center 121 of the cylinder.

Embodiment 3

[0057] Such as image 3 The shown right-angle air distribution suspension piston engine differs from Embodiment 1 in that the piston 2 is designed as an integrated structure, the cylinder 1 is made of the cylinder suspension section 11 and the cylinder sealing section 12, and the cylinder suspension section 11 and the piston 2 Suspension setting or quasi-suspension setting, the cylinder sealing section 12 is in sealing and sliding contact with the piston 2 .

Abstract

The invention discloses a right-angled distribution engine with a suspension piston, which comprises a cylinder 1 and a piston 2. The sidewall forming part of the cylinder 1 for suspension or quasi-suspension of the piston 2 is provided with one or a plurality of lower sidewall distribution channel(s) 5001, the sidewall of the cylinder 1 in each lower sidewall distribution channel 5001 is provided with one or a plurality of lower sidewall distribution base opening(s) 4, and a lower sidewall distribution valve 5 is arranged at each lower sidewall distribution base opening 4 and is controlled by a lower sidewall distribution valve timing control mechanism 6 to open or close the lower sidewall distribution base opening 4 according to a timing relationship. Since the valve seat opening on the side face of the cylinder is arranged above the seal section of the piston, the invention can avoid the engine oil from being scraped into the channel, thereby preventing the engine oil scraped into the channel from flowing into the combustion chamber or being directly discharged into the atmosphere, reducing the environmental pollution and prolonging the service life of the engine.

Description

technical field [0001] The invention relates to the field of engines. Background technique [0002] In a traditional two-stroke engine, the piston is in a sliding and sealed connection with the inner wall of the cylinder. In order to maintain the relative movement between the piston and the cylinder, it is necessary to use oil to lubricate the piston and cylinder. Although this has played a lubricating effect, in the structure where the air passage of the two-stroke engine is arranged on the side wall of the cylinder, the machine oil will enter the combustion chamber with the air flow, and the combustion of the machine oil in the combustion chamber is insufficient. The emission performance of the two-stroke engine is reduced, excessive harmful emissions are produced, and the environment is polluted, or the engine oil will directly enter the exhaust passage and be discharged into the atmosphere with the exhaust gas of the engine, causing more serious environmental pollution. ...
