Abstract

The invention discloses an air valve correct time-lift adjusting mechanism to overcome the disadvantage that an existing engine air valve is fixed in correct time and lift. The air valve correct time-lift adjusting mechanism comprises an air valve, an L-shaped support, a swing arm, a rack, a first reset spring, a pin a, a first stepping motor, a gear, a connecting device, a guide rail, a connecting plate, a connecting rod, a second stepping motor, a rotary arm, a pin b, a bent stick connecting rod, a pin c, a pin d, a cam, a second reset spring, an air cylinder cover and a swing arm support. The L-shaped support is fixedly connected to the air cylinder cover, and the connecting device and the second stepping motor are mounted on the L-shaped support. The swing arm drives the air valve to be opened and closed, the upper half portion of the rack is arranged between the guide rail and the gear, and the lower end of the rack is arranged on the upper surface of the swing arm. The first stepping motor is mounted on the connecting device, and the gear is fixedly connected to the first stepping motor and engaged with the rack. The guide rail is fixedly connected to the connecting plate, and slidably connected with the upper half portion of the rack. The connecting rod is connected with the bent stick connecting rod and the rack, and the rotary arm is fixedly connected to the second stepping motor. The upper end of the bent stick connecting rod is connected with the pin b, and the lower end of the bent stick connecting rod is connected with the cam.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a valve timing-lift adjustment mechanism. Background technique [0002] The valve mechanism is one of the important components of the internal combustion engine. It plays an important role in realizing the opening and closing timing of the intake and exhaust valves of each cylinder of the engine and controlling the movement law of the valve lift. It is to realize the engine ventilation process and ensure the internal combustion engine. The basis for the work cycle of thermal power conversion to go on again and again. Therefore, whether the engine can work reliably, whether its power and economy can be guaranteed, is closely related to the selection of the valve timing and lift of the valve train in the process of realizing the ventilation. Due to the fixed structure of the traditional engine, the valve timing and lift are fixed during the operation of the engine. The...
