Abstract

The invention discloses a a piston type internal combustion engine variable compression ratio adjusting device. The device comprises a force transmission rod for being connected with a piston, a connecting rod, a swing rod and a cam, and the force transmission rod is used for transmitting the explosive force of a piston to the swing rod; the connecting rod is provided with a large head end and a small head end, and the large head end of the connecting rod is connected with a crankshaft for transmitting power to the crankshaft to drive the crankshaft to conduct rotation output; the left end ofthe swinging rod is rotatably connected with the force transmitting rod through a swinging rod pin, and the right end of the swinging rod is rotatably connected to the small head end of the connectingrod through a swing rod; the cam is provided with a cam shaft, the cam is an eccentric circular structure, the center of rotation of the cam shaft deviates a certain distance from the center of the cam, the cam shaft is mounted on a bearing hole of a body, the middle of the swing rod is mounted on the cam, and the swing rod is rotated around the cam shaft through the cam to change the center of the rotating and swing of the swing rod, thereby changing a top dead center of the piston. The device changes the compression ratio by changing the top dead center of the piston, and the compression ratio is continuously adjustable.

Description

technical field [0001] The invention relates to a variable compression ratio adjusting device of a piston type internal combustion engine, which belongs to the technical field of automobiles. Background technique [0002] At present, the most widely used engine is the piston internal combustion engine, and its very important working parameter, the compression ratio, is generally fixed. Since the compression ratio has a great influence on the economy, power and emission performance of the engine, and the operating conditions of the engine are ever-changing, in order to achieve good performance, the requirements for the compression ratio of the engine under different working conditions are Therefore, designing a variable compression ratio device can improve the performance of the engine under various operating conditions and achieve the required performance indicators. Existing variable compression ratio device such as the device of Toyota Motor Corporation is to change the r...
