As shown in Figure 1, Figure 2 and Figure 3, in the present invention, the running length of the running length of plunger 7 and piston 3 is consistent, and has above to point with down to point, and is divided into four strokes, is respectively: aspirating stroke, compression stroke, expansion stroke and exhaust stroke.Below just introduce respectively aspirating stroke, compression stroke, expansion stroke and exhaust stroke:
Aspirating stroke: when piston 3 during in air inlet, plunger 7 does not change to point upper, can guarantee like this maximum volume amount in cylinder.
Compression stroke: when piston compression, the compression ratio that corresponding stroke adjusting reaches appointment is made in the instruction that plunger 7 can send according to the ECU control system;
When the little load of motor, now the ECU control system can be learnt according to each sensor signal, thereby then send instruction, goes downwards to certain position to solenoid valve 10 order plungers 7 and cylinder inner volume volume is diminished reach the high compression ratio of appointment;
When the large load of motor, now the ECU control system can be learnt according to each sensor signal, thereby at this moment plunger 7 does not change to guarantee that to putting the volumetric capacity amount in cylinder reaches the low compression ratio of appointment upper.
Expansion stroke: when motor moves downward acting at control piston 3, plunger 7 can come and then piston 3 to do work together with same speed and stroke, when piston 3 is descending, plunger 7 is also descending, thereby the volumetric capacity in the change cylinder reaches the purpose that changes cylinder bore, thereby improve the inner pressure of air cylinder value and combustion efficiency promotes power, saves oil consumption, reduces discharge.
Exhaust stroke: when cylinder exhaust, plunger 7 can be up along with piston 3 exhausts, improve the force value of gas in cylinder by the volume in the change cylinder, thereby increase exhausting waste gas pressure, make the rotating speed of turbosupercharger promote, then bring the increase of air inflow, improved combustion efficiency, promote the power of motor.
When exhaust stroke finishes, piston 3 has been got back to again to point.Also just completed a work cycle.Subsequently, under the effect of inertia that the bent axle in motor relies on the flywheel in motor to rotate, still continue rotation, start so next circulation.So go round and begin again, motor just constantly gets into smooth.
Utilize this running of cylinder of the present invention, can make the interior fixedly compression ratio of cylinder from changing between 8:1 to 14:1, motor adopts high compression ratio when little load, when large load, adopt low compression ratio to realize saving oil consumption, promote power, reduce discharge, this stroke adjusting for cylinder can be referred to as variable compression ratio stroke adjusting technology.Variable compression ratio stroke adjusting technology is to realize that perfect air fuel ratio is theoretical and to improve the compression ratio concept.Wherein, compression ratio is defined as: the ratio of cylinder total volume and combustion chamber volume.Therefore the compression ratio that changes cylinder can be realized by the swept volume of change cylinder and the volume of firing chamber.
In the present invention, variable compression ratio stroke adjusting technology is to have increased by two plungers 7 of stroke adjusting up and down on original engine cylinder cap 2, thereby plunger 7 can any up and down volumetric capacity that changes cylinder change compression ratio in cylinder, and its compression ratio range can be from changing between 8:1 to 14:1.When the little load of motor, adopt high compression ratio with capable of saving fuel oil; Adopt low compression ratio when the large load of motor, and be aided with pressurized machine and realize that high-power and high moment of torsion exports.
In the present invention, variable compression ratio stroke adjusting technical application is in diesel engine, petrol engine or even natural gas engine.Difference maximum between them is the difference of combustion manner, and the characteristic of oil is different and temperature and condition burning are different.Such as diesel engine is compression-ignited, its compression ratio range is between 18 to 22; And petrol engine and natural gas engine are Spark ignition types, its compression ratio range is between 8 to 14.The combustion characteristic of gasoline has caused the petrolic mixture pressure can not be too high.If the pressure of cylinder has surpassed critical value, pinking will occur, affect like this power output.Especially supercharged engine, can cause again motor when pressurized machine is not got involved fully if reduce compression ratio, and combustion efficiency is very low, few many of the power that the power that can produce produces than the motor of common natural aspiration.
Variable compression ratio stroke adjusting technology has following advantage: improved the thermal efficiency of motor, improved to a great extent the fuel economy of motor, be conducive to reduce discharge; There is good fuel tolerance; In the situation of identical output power, can reach the small-displacement high-power high pulling torque; The power character when fuel economy while taking into account sub load and large load, also avoid the pinking risk in combustion process when improving the low engine speed power performance.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
