The invention discloses a variable lift compression ratio connecting rod mechanism of an engine. The variable lift compression ratio connecting rod mechanism comprises a connecting rod lower part, a motor seat, a motor stator, a motor rotor, an inner sleeve and a connecting rod upper part, wherein the motor seat is mounted in an inner hole at the top end of the connecting rod lower part and fixedly connected with the connecting rod lower part; the motor stator is mounted in a circular ring body at the center of the motor seat and fixedly connected with the motor seat; the motor rotor is mounted in a center hole of the motor stator; the inner sleeve is mounted around the motor rotor and the motor stator in a sleeving manner; the connecting rod upper part is mounted at the top end of the connecting rod lower part and can slide up and down along the connecting rod lower part; the inner wall of the connecting rod upper part is in threaded connection with the outer wall of the inner sleeve; and a mounting hole in the inner sleeve is in key connection with a shaft arranged at the top end of the motor rotor. By adoption of the variable lift compression ratio connecting rod mechanism, the problem that the variable compression ratio of a conventional connecting rod mechanism is not obvious and other problems can be effectively solved. The invention further discloses the engine comprising the above variable lift compression ratio connecting rod mechanism.
Description
technical field [0001] The invention relates to the technical fields of machinery, thermal energy and engines, in particular to a variable lift compression ratio connecting rod mechanism. In addition, the present invention also relates to an engine comprising the above-mentioned variable lift compression ratio link mechanism. Background technique [0002] The compression ratio indicates the degree of compression of the gas, which is the ratio of the volume of the gas before compression to the volume of the gas after compression, that is, the ratio of the total volume of the cylinder to the volume of the combustion chamber is called the compression ratio. During the compression process, the piston moves upwards. In addition to squeezing the mixed gas to reduce its volume, two phenomena, eddy current and turbulent flow, also occur at the same time. Increasing the compression ratio can effectively improve the performance and efficiency of the engine. A large compression ratio...
