Abstract

A continuous variable compression ratio engine comprises a crankshaft, a crankshaft eccentric sleeve, a correct timing end offset axis driver, a flywheel end offset axis driver and a control shaft. The crankshaft eccentric sleeve is mounted on the main journal of the crankshaft. The control shaft adjusts the deflection angles of the crankshaft eccentric sleeve through a chain, a pull rod or a gear mechanism to allow the axis position of the crankshaft to deflect so as to change the positions of the stop point on a piston, and engine compression ratio change is achieved. The correct timing end offset axis driver and the flywheel end offset axis driver are respectively mounted at two ends of the crankshaft of the engine, the position-changed crankshaft axis power output is converted into fixed axis power output. The continuous variable compression ratio engine is simple in structure and low in cost, the correct timing system of the engine and the outer part structure of the engine are the same as a traditional engine, the engine can be obtained by improving the existing fixed compression ratio engines, and large change of engine structure can be avoided.

Description

【Technical field】 [0001] The invention relates to the technical field of automobile engines, and is used for continuously adjustable compression ratios of piston internal combustion engines. 【Background technique】 [0002] In recent decades, in order to improve the power, economy and reduce pollutant emissions of automobile engines, many engine manufacturers and scientific research institutions have invested a lot of manpower and material resources in the research and development of new technologies. The variable compression ratio technology of engines is One of the important new technologies. [0003] The compression ratio of the engine cylinder has a great influence on the performance of the internal combustion engine. Generally, on the premise of ensuring that knocking does not occur in the engine cylinder, increasing the compression ratio as much as possible is beneficial to the improvement of engine performance. [0004] The engine can withstand different compression ...
