Problems solved by technology

The air distribution seat and the valve body (that is, the valve) of the traditional engine are inwardly opened. This structure is good for improving the sealing between the air distribution seat and the valve body, but the inwardly opened valve body structure makes the airflow flow performance, airflow area, and valve opening time are all severely limited

Abstract

The invention discloses an overhead outside opening gas distribution two-stroke engine; a cylinder cover is provided with a reverse-mounted outside opening gas inlet seat hole which is communicated with a gas inlet channel and provided with a reverse-mounted outside opening gas inlet valve body; the cylinder cover is also provided with an exhaust seat hole which is communicated with an exhaust duct and provided with an exhaust valve body; gas inlet collecting structure and / or diversion structural body are / is arranged, wherein the gas inlet collecting structure is positioned on the reverse-mounted outside opening gas inlet seat hole or the cylinder cover at the reverse-mounted outside opening gas inlet seat hole, and the diversion structural body is arranged between the reverse-mounted outside opening gas inlet seat hole and the exhaust seat hole; and the reverse-mounted outside opening gas inlet valve body is controlled by a two-stroke gas inlet timing control device to open or close the reverse-mounted outside opening gas inlet seat hole, and the exhaust valve body is controlled by a two-stroke exhaust timing control device to open or close the exhaust seat hole. The two-stroke engine can reduce the throttle loss of gas distribution and improve the air current flow inside a cylinder and the mixing degree of gas, thus increasing the efficiency of the engine.

Description

technical field [0001] The invention relates to the field of engines. Background technique [0002] How to accurately and efficiently distribute air to the engine is one of the most important technical means to improve engine efficiency and environmental protection. Therefore, research in this area is also very active. The air distribution seat and the valve body (that is, the valve) of the traditional engine are inwardly opened. This structure is good for improving the sealing between the air distribution seat and the valve body, but the inwardly opened valve body structure makes the airflow flow The design of performance, air flow area and gas distribution opening time are all severely limited. Therefore, in order to fundamentally solve the gas distribution problem of the engine, it is necessary to invent a new engine. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention discloses an overhead two-stroke engine with ...
