Abstract

The invention discloses a length variable connecting rod which comprises a connecting rod main body, an eccentric part, a limiting component and a valve core. According to the connecting rod disclosedby the invention, an effective length of the connecting rod can be controllable and variable, so that the compression ratio of a gasoline engine is changed, the thermal efficiency of partial load ofthe gasoline engine can be improved, engine knocking during full load can be avoided, and the reliability and economical efficiency of the engine are effectively improved. The length variable connecting rod disclosed by the invention is simple and reliable in structure, small in size, low in cost and excellent in applicability of the existing volume production models. The length variable connecting rod disclosed by the invention is also applicable to a diesel engine.

Description

technical field [0001] The invention relates to the field of gasoline and diesel engine combustion systems. Background technique [0002] Currently existing solutions: [0003] 1. The compression ratio of the engine combustion chamber is immutable, which cannot solve the contradiction between fuel consumption and knocking. [0004] 2. The compression ratio of the engine combustion chamber is variable, but the structure is complicated, the cost is high, the reliability is poor, and the scheme is difficult to implement. Contents of the invention [0005] The purpose of the present invention is to provide a controllable and variable length connecting rod, thereby changing the compression ratio of the engine; it has the beneficial effects of simple and reliable structure, small volume, low cost, and good applicability to existing mass-produced models. [0006] In order to realize above-mentioned technical purpose, the present invention adopts following technical scheme: [...
