Problems solved by technology

[0003] The theory of thermal efficiency shows that the higher the compression ratio, the higher the thermal efficiency and the lower the fuel consumption. However, increasing the compression ratio will cause knocking. Considering the suppression of knocking, the upper limit of the compression ratio will be limited. Most of the existing engines are fixed compres

Abstract

The invention discloses an engine and a vehicle with the engine. The engine comprises a piston, a crankshaft, an adjusting element, a connecting rod and a compression ratio adjusting mechanism. A connecting rod neck is sleeved with the adjusting element, the connecting rod is connected between the piston and the adjusting element, the distance from the connecting rod neck to the connecting rod isL6, the adjusting element suffers force Fa from the connecting rod, the compression ratio adjusting mechanism comprises an eccentric shaft and a control rod, the control rod is connected between the adjusting element and the eccentric shaft, the control rod is eccentrically connected with the eccentric shaft so that the adjusting element can rotate around the connecting rod neck sleeved by the adjusting element when the eccentric shaft is rotated, the distance from the connecting rod neck to the control rod is L7, the force Fa is distributed to the crankshaft and the control rod through the adjusting element, the force applied by the adjusting element to the crankshaft is Fb, force applied to the control rod is Fc, Fb and Fc are positively correlated to L6/L7 and Fa, and Fb is larger thanFc. By adjusting the arrangement structure or the size of the parts, the force transmitted to the eccentric shaft is small, the wear of the parts is reduced, the driving force of the eccentric shaft is reduced, and the force transmitted to the crankshaft is large enough.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an engine and a vehicle with the same. Background technique [0002] The compression ratio of the engine refers to the ratio of the cylinder volume when the piston moves to the bottom dead center to the combustion chamber volume when the piston moves to the top dead center. Most of the existing engines are fixed compression ratio engines, which have low fuel combustion efficiency, poor economy and high emissions. With the development of variable compression ratio technology, the engine began to increase the compression ratio adjustment mechanism, and the volume of the combustion chamber was changed by changing the position of the top dead center of the piston, thereby changing the compression ratio. [0003] The theory of thermal efficiency shows that the higher the compression ratio, the higher the thermal efficiency and the lower the fuel consumption. However, increasing the compres...
