    摘要: The present invention provides an engine with variable compression ration comprising a cylinder cover, a cylinder body, a power output shaft and a crankshaft box, the cylinder cover is fixed on the cylinder body, the crankshaft box is formed with the cylinder body integrally; In the cylinder body, an piston is connected with a crankshaft via a connecting rod; the power output shaft is mounted on the crankshaft box; a power output gear is placed on the power output shaft, an input gear is placed on a crank journal of the crankshaft, the power output gear engages with the input gear; A supporting arm is placed in the crankshaft box, the crankshaft is hinged on the supporting arm; one end of the supporting arm is hinged on the crankshaft box, and the hinging shaft is the power output shaft; the other end of the supporting arm is a control end, the control end is connected with a rotation control mechanism, which can make the supporting arm rotate around the power output shaft. Since the rotation control mechanism is used to make displacement control over the control end of the supporting arm, the compression ratio of engine matches the engine behavior, so that the efficiency is improved while the emission is reduced.

    摘要: A variable valve lift system for an internal combustion engine includes a roller rocker lift mechanism and a driving mechanism. A cam and a roller of the roller rocker lift mechanism cooperate with each other to control valve lift. The roller rocker lift mechanism includes a second rocker arm, wherein one end of the second rocker arm is connected with the driving mechanism by a rotation pin so as to create a straight-line displacement of the driving mechanism; the second rocker arm is provided with a guideway in the direction of the straight-line displacement; a rocker-arm pin of the roller rocker lift mechanism is slidably set in the guideway of the second rocker. According to actual work condition of the internal combustion engine, the valve lift is regulated by a motor; and continuous variable valve lift is provided from low speed to high speed.

    摘要: A variable valve lift system for an internal combustion engine includes a roller rocker lift mechanism and a driving mechanism. A cam (7) and a roller (8) of the roller rocker lift mechanism are cooperated with each other so as to control the valve lift. The driving mechanism can output straight-line displacement driving force. The roller rocker lift mechanism includes a second rocker arm (10), wherein one end of the second rocker arm (10) is connected with an output portion of the driving mechanism by a rotation pin (16) so as to create a straight-line displacement by the driving force of the driving mechanism; the second rocker arm (10) is provided with a guideway in the direction of the straight-line displacement;a rocker-arm pin (14) in the center of valve rocker arms (15,15′) of the roller rocker lift mechanism is set in the guideway of the second rocker arm (10); the rocker-arm pin (14) can slide in the guideway of the second rocker arm (10). According to actual work condition of the internal combustion engine, the valve lift is regulated by a motor; and continuous variable valve lift is provided from low speed to high speed. The internal combustion engine is provided with the best valve lift in work condition range.
