Continuously variable compression ratio engine and power output device thereof

Abstract

The invention discloses a continuously variable compression ratio engine and a power output device thereof. The engine comprises a crankshaft, an integrated crankshaft deflection support body, a crankshaft bearing cover, a crankshaft timing gear part, a control driving mechanism, a flywheel, an eccentric clutch and a transmission input shaft, wherein the control driving mechanism has braking and locking functions. The original design thought is that: when the flywheel and the eccentric clutch are eccentrically rotated along with the crankshaft simultaneously, a difficult engine variable compression ratio problem is converted into an eccentric clutch designing problem. The engine and the device aim to completely solve the technical problems of variable compression ratio engines which make human beings troubled for nearly a century, and struggle for saving one third of energy in the world and returning a sustainable green environment to the world.

Description

Technical field [0001] The invention relates to a continuously variable compression ratio engine and a power output device thereof, which is used for enabling the compression ratio of the engine to be continuously variable according to the requirements of specific working conditions. Background technique [0002] Engine designers know that continuously variable compression ratio technology and continuously variable valve lift technology are the two most cutting-edge technical problems of reciprocating engines. It can be said that human design of engines is developed around these two major problems, or the engine Most of the new technologies are continuously variable compression ratio technology and continuously variable valve lift technology compensation technology. At present, with the perfect solution of the continuous variable valve lift technology of the engine, the continuous variable compression ratio technology that has plagued the engine industry for nearly a century is a...

[0013] 2. Design Difficulties of Variable Compression Ratio Technology

[0020] 3. There is an eccentric support sleeve on the piston pin. The core problem is that the eccentric support sleeve on the piston pin makes the connecting rod deviate too much from the cylinder axis, which causes the cylinder to wear out or even pull the cylinder; the design of the control mechanism is difficult. Auxiliary linkage controls are not a good solution

[0023] 6. The eccentric sleeve is added to the crank pin. This method can realize variable compression ratio, but the friction energy consumption is large.

The core of this mechanism is the controllable swing of the cylinder, and the space angle of the swing of the cylinder is very large, so that the piston axis at the top dead center deviates from the radial direction of the crankshaft, thus causing the cylinder bias problem

In addition, the mechanism mechanism is complex, the control actuation force and maintenance force are large, and it also involves the problem of gas distribution shock, cooling and sealing problems, and the stability of the engine body.
