A circuit controller is connected with an engine rotating speed sensor through a first wire, is connected with an electrical machine through a second wire, and is connected with a counting sensor through a third wire. The counting sensor is mounted on the electrical machine. An upper piston connecting rod and a lower piston connecting rod are combined into a whole in a connecting mode through a thread rod with a gear. The electrical machine and the counting sensor are installed in the connecting rod combination. The engine with the changeable compression ratio can precisely control the compression ratio of the engine and is fast in response and sturdy in structure.
Description
Technical field
The utility model relates to a kind of engine variable compression ratio mechanism, specifically can realize the engine compression ratio can regulate.
Background technique
In prior art, conventional engines all is the compression ratio of fixing, and has occurred variable compression ratio engine in recent years abroad.The maximum effect that changeable compression ratio technique brings is the motor of little discharge capacity, also exportable power and the moment of torsion that can compare mutually with large-duty engine, and oil consumption is still less, discharges lower.Changeable compression ratio technique is complicated, and at present, variable compression ratio engine was not also met report in China.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of conventional engines, thereby a kind of mechanism that can realize the engine compresses variable ratio is provided, to reach purpose fuel-efficient, low emission.
According to the technological scheme that the utility model provides, engine variable compression ratio mechanism comprises: connecting rod, piston lower link, motor, motor gear, counting sensor, engine rotation speed sensor, circuit controller on the threaded stem of band gear, the piston.Circuit controller links to each other with engine rotation speed sensor through first lead, links to each other with motor through second lead, links to each other with counting sensor through privates.The threaded stem of band gear has 4, and its smooth end is installed on the hole, garden on the piston lower link base, fixes with jump ring; Can rotate; The threaded part in other end changes the tapped hole on the connecting rod base on the piston over to, and threaded stem and piston upper and lower strut form a connecting rod assembly like this, are an integral body; Replace traditional piston rod, motor, counting sensor and motor gear are installed in the inside, whole the inside that forms.Counting sensor is fixed on the motor top; The motor afterbody is fixed on the base of connecting rod on the piston; Motor shaft passes counting sensor and inserts the circular hole on the piston lower link base; Motor shaft stretches at the base circular hole has 2 to 3 millimeter spaces, and this is because the distance between the upper and lower strut can change.Motor sprocket is fixed on the motor shaft, with the gear engagement on 4 screw threads.
Compared with present technology the utility model has the following advantages:
The utility model easy processing simple in structure, firmly, control accurately; Can improve engine fuel Economy and engine power performance; Help reducing and discharge pollutants.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is motor gear and threaded stem gear structure schematic representation.
Embodiment
Following the utility model will combine the embodiment in the accompanying drawing to further describe:
The utility model mainly is made up of threaded stem 10, motor gear 11, the jump ring 12 of connecting rod 8, piston lower link 9, band gear on motor 1, second lead 2, circuit controller 3, first lead 4, engine rotation speed sensor 5, privates 6, counting sensor 7, the piston.
The utility model adopts engine rotation speed sensor 5 through first lead, 4 connecting circuit controllers 3.Said circuit controller 3 is connected with motor 1 through second lead 2, is connected with counting sensor 7 through privates 6.Counting sensor 7 is installed on the motor 1; Motor gear 11 is fixed on the motor shaft; Motor 1 afterbody is fixed on the piston on connecting rod 8 bases, and motor shaft passes counting sensor 7 and inserts the circular hole on piston lower links 9 bases, the gear engagement on the threaded stem 10 of motor gear 11 and band gear.The threaded stem 10 of band gear has 4, and its smooth end is installed on the hole, garden on piston lower link 9 bases, and is fixing with jump ring 12; Can rotate; The threaded part in other end changes the tapped hole on connecting rod 8 bases on the piston over to, and connecting rod 8, piston lower link 9 form a connecting rod assembly on the threaded stem 10 of this belt transect gear and the piston, are an integral body; Replace traditional piston rod, motor 1, counting sensor 7 and motor gear 11 are installed in the whole the inside that forms.
Working principle of the utility model and working procedure:
In instance shown in Figure 1, when engine rotation speed sensor 5 detected engine speed above the regulation revolution, engine rotation speed sensor 5 transmitted signals through first lead 4 and gives circuit controller 3, and circuit controller 3 is started working.Circuit controller 3 is through 1 work of second lead, 2 control motors, and motor gear 11 rotates synchronously, and motor gear 11 drives threaded stem 10 rotations of band gear.When threaded stem 10 rotation of band gear, threaded part produces axial motion because of rotation, makes that connecting rod 8 produces displacements on the piston, and the distance between the piston lower link 9 just changes, and the volume of firing chamber just changes like this, and compression ratio has just changed.Counting sensor 7 is the number of times of monitoring motor 1 rotation in real time, signals to circuit controller 3 through privates 6, and when reaching necessary requirement, circuit controller 3 control motors 1 quit work.The same with the fuel pump in automobile is immersed in fuel oil, motor 1 all is processed into sealing, insulation with counting sensor 7.Four stroke engine only when expansion stroke connecting rod stressed a little bigger, other stroke connecting rods are stressed little, add that structure drenches full machine oil, and are quite lubricated, so that power of motor does not need is very big.
With 1.6 liter of 481 motor is example, 81 millimeters of cylinder diameters, if compression ratio changes to 10.5 from 8.5, as long as this novel link is 1.74 millimeters of elongations.Through the clockwise and anticlockwise of motor 1, can control piston on distance between connecting rod 8 and the piston lower link 9 change, thereby increase or dwindle engine compression ratio.Control the motor 1 in each connecting rod assembly along separate routes by circuit controller 3, can accurately control the compression ratio of each cylinder, guarantee that the compression ratio of each cylinder is consistent.
