Abstract
The invention discloses an engine connecting rod mechanism with a variable compression ratio. An existing engine connecting rod mechanism is characterized in that once the engine connecting rod mechanism is designed, the compression ratio of an engine cannot be changed through a connecting rod and the performance of the engine cannot be fully exerted due to a fixed compression ratio. According to the engine connecting rod mechanism with the variable compression ratio, the working length of the connecting rod is stretched out and drawn back through connecting rod structures of inner and outer combination bodies; the engine connecting rod mechanism is characterized in that the compression ratio of the engine can be changed and the performance of the engine can be fully exerted.
Description
Technical field
The present invention is a kind of engine link mechanism.
Background technique
The length of present engine connecting rod is changeless, it is characterized in that cannot changing by connecting rod the compression ratio of motor once just designing, fixing compression ratio can not be given full play to the performance of motor, while causing little load, low-speed running, the thermal efficiency of motor is low, and corresponding combination property is poor, and when loading greatly, running up, easily there is pinking and produce very large heat load and mechanical load, illustrating that present engine linkage mechanism is to be improved.
Summary of the invention
The object of the invention is the flexible compression ratio that changes motor by connecting rod active length, give full play to the performance of motor, when the little load of motor, low-speed running, by the elongation of connecting rod active length, improve the compression ratio of motor, thereby the thermal efficiency and the combination property that improve motor, when loading greatly, running up, reduce the compression ratio of motor by the shortening of connecting rod active length, prevent pinking, avoid producing very large heat load and mechanical load.
Accompanying drawing explanation
Accompanying drawing is the engine link structural scheme of mechanism of this invention, and it is comprised of lower cover (16), connecting rod enclosing cover (17), hyperbaric chamber (18), one-way valve (19) in upper cover (13), connecting rod inner bolt (14), connecting rod outer bolt (15), connecting rod in connecting rod shank (10), one-way valve (11), hyperbaric chamber (12), connecting rod; Engine rotation speed sensor in accompanying drawing (1), engine control module (2), OCV Oil Control Valve (3), cylinder-body oil duct (5), main oil gallery (6), one-way valve (7), cylinder-body oil duct (8), bent axle (9) are the control system of this invention, and plunger (4) is a part for OCV Oil Control Valve (3).
Embodiment
After piloting engine, engine control module (2) is by engine rotation speed sensor (1) signal judgement engine speed, when engine speed is positioned at the slow-speed of revolution, OCV Oil Control Valve (3) is closed, machine oil in main oil gallery (6) is by one-way valve (7), cylinder-body oil duct (5), bent axle (9) oil duct, one-way valve (11) enters hyperbaric chamber (12), the interior assemblying body that makes upper cover (13) and the interior lower cover (16) of connecting rod in connecting rod moves down along the guiding groove of the outer assemblying body of connecting rod shank (10) and connecting rod enclosing cover (17), the active length of extending connecting rod improves the compression ratio of motor, thereby improve the slow-revving thermal efficiency of motor and combination property, compression, acting, one-way valve during exhaust stroke (11) is closed the fluid making in hyperbaric chamber (12) and cannot be overflowed, and the incompressibility that fluid has makes the connecting rod of this invention promote crankshaft rotating as an integral body, in this process, because the oil pressure in hyperbaric chamber (12) is very high, there is a little fluid to let out and make connecting rod active length " shortening " by the gap location of upper cover (13) in connecting rod shank (10) and connecting rod, oil pressure in hyperbaric chamber during intake stroke (12) declines thereupon, so pushing one-way valve (11) once more open, injects in hyperbaric chamber (12) in the machine oil of main oil gallery (6), supplement fluid, repetitive cycling is moved above, when engine speed is positioned at high rotating speed, OCV Oil Control Valve (3) is connected, plunger (4) moves down, machine oil in main oil gallery (6) is by one-way valve (7), cylinder-body oil duct (8), bent axle (9) oil duct, one-way valve (19) enters hyperbaric chamber (18), the interior assemblying body of lower cover (16) in the interior upper cover (13) of connecting rod and connecting rod is moved on the guiding groove of the outer assemblying body of connecting rod shank (10) and connecting rod enclosing cover (17), the active length that shortens connecting rod reduces the compression ratio of motor, prevent pinking, avoid producing very large heat load and mechanical load, one-way valve during intake stroke (19) is closed the fluid making in hyperbaric chamber (18) and cannot be overflowed, and the incompressibility that fluid has makes the connecting rod of this invention follow crankshaft rotating as an integral body, in this process, because the oil pressure in hyperbaric chamber (18) is high, there is the gap location of a little fluid by lower cover (16) in connecting rod and connecting rod enclosing cover (17) to let out and make connecting rod active length " elongation ", compression, acting, oil pressure in hyperbaric chamber during exhaust stroke (18) declines thereupon, so pushing one-way valve (19) once more open, injects in hyperbaric chamber (18) in the machine oil of main oil gallery (6), supplement fluid, repetitive cycling is moved above.
