Abstract

The invention discloses a generator with continuous variable volume compression ratio, comprising a sensor, a box body, a bent axle, at least one connecting rod and a piston, wherein one end of the connecting rod is rotatablely connected with an outer shaft cervical collar installed on a shaft neck; the shaft neck of the bent axle is provided with a continuous variable volume compression ratio mechanism which is controlled by a circular ring orbit installed in the box body; a fixed mechanism which is arranged on the box body is provided with the control mechanism of the generator with the continuous variable volume compression ratio; the control mechanism controls the circular ring orbit to control different positions for the outer shaft cervical collar to be sheathed on an upper dead center and a lower dead center to realize different compressed heights and compression ratio so as to improve fuel economy and dynamic property.

Description

Technical field [0001] The invention relates to a variable reduction ratio technology of an engine, which can allow different compression ratios to be realized by controlling the different compression heights of the piston at the top dead center. Background technique [0002] With the increasingly stringent emission regulations and customer requirements for engine economy, improving engine emission performance and fuel economy has become the biggest difficulty faced by traditional internal combustion engines. Now engines mainly use three-way catalysts to change emissions, and to improve fuel economy, they mainly use in-cylinder direct injection and variable valve technology. In order to further reduce emissions, many new combustion modes have now emerged. These new combustion modes mainly pursue low-temperature combustion and the formation of homogeneous mixtures, which require low charge temperature and uniform mixtures, as well as lower compression ratios to reduce NOX and PM ...
