Abstract
Improve power of IC engine, the method of efficient, it is fuel work characteristic according to internal-combustion engine, on the energy transfer component of internal-combustion engine, elastic mechanism is set, in the process of boosting of fuel detonation, elastic mechanism makes piston shift to an earlier date displacement, increased combustion chamber volume, chamber pressure can not sharply be risen, the buffer function of formation during to fuel detonation, the vibrating noise of internal-combustion engine descends simultaneously like this, and chamber pressure reduces can reduce piston ring, the air loss of valve, middle pressure is raise, can improve power of IC engine and efficient, also just for internal-combustion engine increases cylinder diameter, improve single-machine capacity and created condition simultaneously.
Description
Technical field that the present invention belongs to: heat energy power mechanism.
The prior art data that reference role is arranged: mechanical engineering manual, the 74th piece,
Internal-combustion engine.
Goal of the invention: improve power of IC engine, efficient, the vibration that reduces internal-combustion engine with
Noise, and exhaust pollution.
Summary of the invention:
Technical background: internal-combustion engine is the important component part of modern dynamic power machine, is widely used in the various productions and social activities of human society, and the development trend of internal-combustion engine is with the increase cylinder diameter, improve rotating speed, reduction consumes, increases the service life is target.The cylinder diameter of internal-combustion engine increasing now is restricted.Be no more than 108～117mm as the maximum cylinder diameter of petrol engine, pinking easily takes place when increasing again, it is wayward to burn.Improve rotating speed and will be subjected to inertial force, vibration, the friction merit, the restriction of noise and parts depreciation, internal-combustion engine has adopted a series of new material in recent years, new process, new technology does not fundamentally solve the raising problem of power of IC engine, efficient.
1, limit engine reasons of development:
The firing chamber is the heart of internal-combustion engine, and the structure of firing chamber is the key that influences engine performance.The kind of Modern Internal-Combustion Engine firing chamber is a lot.Though form is different, work cycle is identical basically, when Piston Compression gas reaches certain compression ratio, to be lighted or compression ignite at before top dead center gas, mixed oil, the boost phase of combustion gas is exactly through the process at dead point before the dead point, the variation ratio of the radian of this section bent axle and piston stroke is minimum, can be similar to the appearance stage such as be considered as, so the work cycle of internal-combustion engine approaches the constant volume Heating Cyclic.
2, constant volume heats the influence to internal combustion engine operation:
A, constant volume heating must make gaseous-pressure increase severely, and make cylinder body, piston be subjected to intense impact power, and this is the reason that produces vibrating noise.
Near the impact force that b, piston are subjected to the dead point will act directly on the bent axle, and bearing drag is increased, and not only will cause kinetic energy rejection, also will accelerate the wearing and tearing of bearing.
C, piston ring are parts that sealing is slided again, can not reach the requirement of sealing gas fully, and gaseous-pressure is high more, and air leakage is also just many more, and the valve on the cylinder cap is inevitable also to be increased with pressure rising air leakage, and this just causes the heat-energy losses of combustion gas.
3, improve the method for power of IC engine, efficient:
(1) invention is theoretical: the work cycle of internal-combustion engine will change the dilatation of boosting into, the Hybrid Heating circulation of carrying out simultaneously.
Theoretical operating mode: the vapour above piston, mixed oil reach the compression ratio requirement, before top dead center lighted or compression ignite after, rising along with gaseous-pressure, piston is near upper dead center, have with pressure and rise accordingly to bottom offset, enlarge the volume of firing chamber, make gaseous-pressure maintain in the comparatively ideal scope (as 80,90,100Kg/cm
2).In descent of piston, internal pressure of combustion chamber descends, and piston just recovers original torque length gradually, is the output that belongs to energy in this stage.
(2) Fa Ming method:
The present invention utilizes the spring can be in the characteristic of instantaneous storage and delivered energy, on the energy transfer component of internal-combustion engine, elastic mechanism is set, form the buffering of piston, the Hybrid Heating circulation that internal combustion engine circulation the becoming dilatation of boosting is carried out simultaneously to the detonation gas pressure.
(3) choice of location of elastic mechanism:
Eccentric wheel is the energy storage component of internal-combustion engine, and clear position is bigger, and operating ambient temperature is lower, and lubricating condition is good.It is the ideal position that elastic mechanism is set.
(4) composition of elastic mechanism:
A, spring: it is a major part of forming elastic mechanism.The first kinetic pressure of cluster spring will be higher than the pressure of the required compression ratio of mixed gas detonation in the cylinder.
Limiter on b, the stroke: it is the mechanism of control piston range.
Limiter under c, the stroke: the maximum compression distance of control spring, determine the length of breeze way.
D, slide mechanism: form by dovetail groove and trapezoidal slider, the mortise lock hole is arranged on slider, connect link rod.
4, the use of elastic mechanism on two stroke IC engine:
Transform example as with Chongqing 50A I. C. engine crankshaft eccentric wheel:
Shown in Figure of description (1-1):
Among the figure: the 1-spring
The 2-cap controller
3-lower limit controller
4-slip parts
5, the use of elastic mechanism on 4 stroke IC engines: 4 stroke IC engines, once push the program of exhaust, utilize elastic mechanism, form dimly visible firing chamber and improve ventilation rate.Elastic mechanism just has 4 effects like this:
A, when Piston Compression gas reaches compression ratio, elastic mechanism is compressed, piston is pressed and not to be abdicated a bags to the end.
Behind b, the fuel detonation, the pressure of piston head is acute to be risen, and makes elastic mechanism continue to be compressed, and combustion chamber volume is further increased, and elastic mechanism plays the buffer function to the detonation impact force.
When cylinder pressure was lower than the pressure of elastic mechanism in c, the descent of piston, under the effect of spring, the piston torque returned to Max. torque, and spring is exported energy.
D, open when exhaust valve, when piston pushed exhaust, piston can be up to the extreme higher position, and the waste gas more than 90% is discharged.When piston intake, can suck more air, improve ventilation rate.
4 stroke IC engines can reach the higher thermal efficiency and ventilation rate after using elastic mechanism.
6, use the internal-combustion engine of transformation of the present invention and manufacturing and Modern Internal-Combustion Engine to compare, following advantage arranged:
(1) in the internal combustion engine operation, vibrate little, noise is little.
(2) transform preceding air displacement and increase, the over-emitting black exhaust phenomenon reduces or eliminates fully.
(3) power per cylinder increases, and fuel consumption reduces.
(4) cylinder diameter can increase, at the load-carrying internal-combustion engine of variable load operation, and can be with the supporting use of the internal-combustion engine of large, medium and small three kinds of cylinder diameters.Can reduce the quantity of modern multi-cylinder engine.
(5) can prolong working life of internal-combustion engine.
