Embodiment Construction

[0016] In order to make the purpose, features and effects of the present invention more obvious and understandable, specific implementations of the present invention will be described in detail in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways than described here, so the present invention is not limited by the specific embodiments disclosed below.

[0017] figure 1 It is a schematic diagram of the crankshaft center rocker arm used for a variable effective crank radius mechanism. The mechanism is at least composed of a crankshaft 1, a limit pin 2, a bellcrank rocker arm assembly 3, a crankshaft center rocker arm 4, a connecting rod 5, and a connecting rod pin. The crank side of the crankshaft 1 in the mechanism is equipped with a crank center rocker arm 4, wherein the crank arm side of the cra...

Abstract

The invention discloses a crankshaft center rocker arm for a variable-effective-crank-radius mechanism. A shaft hole is designed in one end of the crankshaft center rocker arm, and a pin hole is designed in the other end in a manner of being parallel to the shaft hole; the shaft hole of the crankshaft center rocker arm is fixedly connected with the end part of a shaft in the crankshaft center hole; and the pin hole in the other end of the crankshaft center rocker arm drives a crank rocker arm assembly on a crank journal to rotate around the crank journal through a connecting rod and a connecting rod dowel.

Description

technical field [0001] The invention relates to the field of internal combustion engines, in particular to the field of variable compression ratios of internal combustion engines. Background technique [0002] The regulations on energy saving and emission reduction are becoming more and more stringent, and various automobile companies and internal combustion engine manufacturers have increased the research on energy saving and emission reduction technologies for internal combustion engines. The variable compression ratio internal combustion engine has advantages in energy saving and emission reduction, but most of the variable compression ratio mechanisms have relatively large changes to the existing internal combustion engines, the mechanism is complicated, the cost is high, and it is difficult to industrialize. For example, the variable compression ratio mechanism of the French MCE5 company. Therefore, it is relatively advantageous to modify the local parts of the existin...
