Crank link mechanism engine

One, the invention process of internal combustion engine

The invention and application of internal combustion engine are built upon on the basis of Principles of Internal-Combustion Engine, and Principles of Internal-Combustion Engine are built upon energy and turn It changes and law of conservation, on the basis of the thermodynamic argument of the first, second law of thermodynamics, undergo following procedure: 18th century are Establish energy conversion and law of conservation --- various energy can be converted mutually, but their total amount be to maintain it is constant.1851 Year Thomson establishes the first law of thermodynamics, formula: Δ U=Δ Q+ Δ A, energy=system capacity variation of input system The energy of+system output is the concrete form of energy conversion and law of conservation in warm-up movement.18 beginning of the century Kanos are to steam engine Theory is in depth studied, and when how to improve efficiency of heat engine, he has bypassed various specific structures and real process, according to heat Matter law of conservation in a Utopian adiabatic compression, determines four Wen Jiare, adiabatic expansion, fixed warm heat release reversible process compositions Carnot cycle, establishes the second law of thermodynamics --- and the maximal efficiency of any heat engine is both less than 1, formula is as follows:

η=1-T1/T2

In formula: T1 --- high temperature heat source temperature, T2 --- low temperature pyrogen temperature

After Kano is died 20 years, Alto and Daimler have been invented mixed with gasoline and air according to Kano thermodynamic argument It is combined into flammable working medium, using crank link mechanism as transmission mechanism, air inlet, compression, work done, the ignition gasoline hair for being vented four strokes Motivation, subsequent Descartes have invented four stroke compression ignition diesel engines.They are made that major contribution to the birth of internal combustion engine. Undergo people to the gradually perfect of internal combustion engine, invented from formula electronic spark advance regulating device, vacuum firing shift to an earlier date regulating device and Octane corrector.Deng.Since the 1970s, using the direct-injection combustion control system under computer control, make interior Combustion engine effective thermal efficiency, less than 10%, is increased to gasoline engine 40% or so, diesel engine 45% or so realizes section by invention initial stage The about purpose of the energy and reduction pollution.

Principles of Internal-Combustion Engine think that the method for improving internal combustion engine thermal efficiency is to improve the compression ratio (expansion ratio) of engine.When Gasoline engine will generate " detonating combustion " when increasing compression ratio, to avoid the damage of " detonating combustion " to engine, in engine cylinder Anti-knock sensor is installed, when going out " detonating combustion ", control system reduces distributive value and amendment electronic spark advance automatically on body Angle.Principles of Internal-Combustion Engine think that it is chemical reason that engine, which generates " detonating combustion ", are working medium flamjne front extension institutes in combustion It generates.

" Principles of Internal-Combustion Engine " book written by masschusetts, U.S.A Polytechnics Tai Leshi brothers in 1938 points out that internal combustion engine generates " detonating combustion " is physical cause, is not chemical reason.The aviation system, book nineteen fifty Tsinghua University translates, and gantry joint publishing house printes and distribute It publishes.

For the year, basis when scientist establishes the first, second law of thermodynamics be under natural conditions heat by high temperature heat source Propagation to low-temperature heat source is all considered as linear motion, when Alto invention is the four-stroke engine for wearing body with crank link mechanism When, the direction of transfer for the maximum pressure (mechanical force) that working medium burning generates is converted to the flywheel of horizontal direction by vertical movement direction Output mechanism energy.The current year compression ratio of internal-combustion engine of invention is at a fairly low, and the thermal efficiency is less than 0.1, so far, the thermal efficiency of internal combustion engine Only 0.4 or so, this problem values obtains people's deep thinking.

The development work for presiding over our unit " rotary engine " for inventor 1969, successfully manufactures experimently into model machine, Loading test is carried out, since some technical problems not can solve and is failed, has just been sprouted without using crank link mechanism engine The idea inquired into.After retiring due to illness within 1992 with regard to stand mechanics principle position to Principles of Internal-Combustion Engine there are the problem of innovate Research, write it is literary (not publicly delivering) at " to the view of problem present in Principles of Internal-Combustion Engine " one, now take passages written by related content Following view is proposed to the problems of internal combustion engine:

One, Fig. 4, crank connecting link are made in the analysis according to mechanics principle to crank and connecting rod movement characteristic and working principle The kinetic characteristic and working principle of mechanism engine, in figure: 1 --- crankshaft center, 2, crankshaft, 3, connecting rod, 4, piston Xiao, 5, living Plug, 6, cylinder, 7 --- inlet valve, 8 --- exhaust valve.5, push crankshaft 2 around garden heart rotation fortune by piston Xiao 4 and connecting rod 3 It is dynamic.Piston linear reciprocating motion is secondary, and crankshaft rotates a circle, and working principle is identical with stone mill.

It is analyzed according to theory of mechanics, it is sinusoidal cam that piston linear reciprocating motion, which pushes the motion profile of crankshaft rotary motion, Curve, equation of motion Y=sinx.So far, influence of the Principles of Internal-Combustion Engine to crank link mechanism to engine thermal efficiency be not Make any research.

Two, influence of the bent bright link mechanism to engine thermal efficiency is inquired into from mechanics principle.

1, the transmission efficiency of crank link mechanism

Crank link mechanism engine power stroke force analysis, such as Fig. 5

In expansion space stroke, gas pressure is to push the power that piston moves downward.At this moment the maximum swelling that combustion chamber generates Pressure acts directly on top land, if the gross pressure that piston is born is P (input power), passes on piston pin, can be analyzed to P₁And P₂.Component P₂Piston is pressed to cylinder wall, forms the lateral pressure of piston and cylinder wall.Component P₁Company is transmitted to by piston pin Bar, and acted on crank-pin along connecting rod direction.P₁Or it can be analyzed to component P on two₃And T.Component P along crank direction₃Make song Axis trunnion and base bearing generate pressing force.The component T vertical with crank other than making trunnion and base bearing generate pressing force, Or torque M=TR is formed to crank, crankshaft rotation is pushed, T is power output.

The above various power, changing rule during expansion space stroke are as follows:

Input power P: After Top Center, burning maximal pressure force is maximum, and with the increase of crank angle, volume of cylinder increases Greatly, P is started decline rapidly by maximum, is minimum when piston is to before bottom dead center, and exhaust valve is opened.

Side pressure of piston P₂: After Top Center, burn maximal pressure force when, P₂For minimum, with the increase P of crank angle₂ By small increase, when piston reaches before bottom dead center, before exhaust valve is opened, P₂For maximum,

Crankshaft normal pressure P₃: it is upper only after, burn maximal pressure force when, P₃For maximum, with the increase of crank angle, P₃ It is descending, it is minimum when exhaust valve is opened.

Power output T: piston it is upper only after, burn maximal pressure force when, T is minimum, and with the increase of crank angle, T gradually increases Greatly, when crank angle is 90 °, T is maximum.

Find out from the above analysis: in crank link mechanism engine working stroke, P is by big-→ small, P₂By small-→ big, P₃ By it is big-→ it is small, T by it is small-→ it is big.Wherein P₂、P₃For loss.

The calculating of crank link mechanism transmission efficiency.

Transmission efficiency η according to theory of mechanics, if input power P is constant, when calculating 0 ° -90 ° of crank angle are as follows:

Make crank linkage transmission efficiency calculation figure, such as Fig. 6, in figure: P- input power, T- power output, b- length of connecting rod, R- crank throw, a- crank angle, β-connecting rod center and crankshaft center angle.

In △ ABC, obtained by sine

It enables

As α=0, t=b

According to the above calculation formula motorcycle, car, lorry, the related parameter of diesel engine crank link mechanism, Substitute into the transmission efficiency such as table one that formula calculates crank link mechanism.

Table one:

Diesel engine 6135	Φ135*140	280	70	4	0.7208

From one analysis of statistical data of table: the ratio between the transmission efficiency of crank link mechanism and b/R are inversely proportional, and Yao Tigao crank connects The transmission efficiency of linkage is to reduce the ratio between b/R, but a possibility that reduction is limited.The transmission efficiency of crank link mechanism is 70% Left and right.

2,0 ° → 40 ° of crank link mechanism crank angle when P → dx specificity analysis

In order to analyze the transformational relation of crank link mechanism active force P, taking P is a constant, calculates power output T, piston side Pressure P₂, crankshaft normal pressure P₃Conversion value, make crank link mechanism Force Calculation figure, such as Fig. 7.

In order to analyze the relationship between the mobile linear velocity of crank link mechanism piston and the peripheral speed of crankshaft rotation, make Crank link mechanism piston moving distance dx calculates figure, such as Fig. 8.

Piston moving distance: dx=b+R- (R cos α+b cos β) ... ... ... ... is 5.

Peripheral speed at 1 ° of crank rotation: v₁π/360 ... ... ... ...=D are 6.

In order to accurately analyze the correlation of crank link mechanism P → dx, have with Santana's crank-connecting rod mechanism for engine 2. 3. 4. 5. 6. parameter is closed, it may be assumed that 1. length of connecting rod b=142, crank throw R=43.2 substitute into calculation formula, by crank angle increasing Add 1 ° of related data such as table two for calculating 0 ° → 40 °.

According to the statistical data of table two, when making 0 ° → 40 ° of crankshaft connecting rod system crank angle, P → dx analysis chart such as Fig. 9.

Found out by analyzing above: in 10 ° of -20 ° of ranges of crank angle, input power P is converted to the low efficiency of power output T, Piston is acted on, the power P3 on crankshaft is relatively large, and the mobile distance dx of piston is small, and speed is slow.

3, crank link mechanism engine can not achieve the Ideal Cycle of internal combustion engine

According to above to crank link mechanism transmission efficiency, speed characteristics, maximum force P and piston moving distance dx Correlation (such as table two, Fig. 8) analysis is found out: when input power P is constant, input power P is converted to (0 ° of efficiency of power output T → 90 ° of ranges) it is by small → big, when volume of cylinder is constant, the incrementss (piston moving distance dx) of volume of cylinder are with song The variation of Shaft angle and change, at 0 ° → 90 ° → 180 ° of crank angle, the incrementss (piston moving distance dx) of volume of cylinder It is by small → maximum → small.

Internal combustion engine working medium generates maximum swelling power P in combustion process (12 ° → 18 ° ranges of crank angle), in expansion working Following four factor is variable: 1. maximum swelling power P in the process；2. maximum swelling power P is converted to the efficiency of T；3. volume of cylinder Incrementss；4. the peripheral speed of piston mobile linear velocity and crankshaft.Maximum swelling power P (when for constant) is converted to the effect of T Rate is 70% or so, so working medium can not be achieved theoretical constant volume heat cycles in work expansions, level pressure heating is followed Ring, dual cycle.Internal combustion engine shows themselves in that the thermal efficiency is low, generates detonating combustion.

4, influence of the crank link mechanism to engine thermal efficiency

The mechanical efficiency of crank link mechanism engine

According to Principles of Internal-Combustion Engine, when determining crank link mechanism engine mechanical efficiency, for more different engines Mechanical loss size introduces the concept of mechanical efficiency:

The effective power of engine, indicated horsepower are to be measured using dynamometer machine to engine test.Common test method There is motoring breakdown and goes out two kinds of cylinder method.

It includes: the friction loss of 1. internal combustion engines movement parts that crank link mechanism, which starts mechanical loss, is 2. driven attached The loss of mechanism, 3. pumping loss, into, consumed function in instroke, above three wasted powers 10% → 30%, So the mechanical efficiency of engine: diesel engine is 70% → 85%, and gasoline engine is 70% → 90%.

It is analyzed according to theory of mechanics: crank link mechanism engine measuring mechanical loss power, indicated horsepower, using towing astern Method, cylinder method of going out are inaccurate.Cylinder pressure differs 50% or so with the cylinder pressure when compression when engine power, not same It is measured under the conditions of one, so the loss that maximum linear movable machinery function acts on 30% of crank link mechanism or so is can not to survey Amount.For the engine of same structure, measured using same method, more different engine mechanical loss sizes are correct.

Current year, U.S. professor Tai Leshi also thought: being also inaccuracy using " blank experiment " measurement frictional force, due to big Family is not also furtherd investigate using same method.

According to Principles of Internal-Combustion Engine: following procedure is the process that engine indicated horsepower is converted to effective power.(it was derived There are problems for journey)

Mean indicated pressure (MIP

W in formula_i--- indicated work [J]；V_h--- displacement [L].

The indicated work that every cylinder, every cycle fluid are done are as follows:

... ... ... ... ... ... the mechanical work of linear motion

Internal combustion engine indicated horsepower (done indicated work per second) are as follows:

See Figure 10

I in formula --- number of cylinders；τ --- number of strokes.

Internal combustion engine effective power are as follows:

M in formula_e--- effective torque [Nm]；N --- revolving speed [rPm].

According to previous analysis: when internal combustion engine uses crank link mechanism to convert heat energy into mechanical energy for carrier, working medium institute The outbound course for the indicated work (mechanical work of linear motion) done, will be converted to rotary motion by linear motion, with rotary motion Mode exports indicated horsepower (mechanical output of linear motion).Its process are as follows: maximum swelling pressure P [kPa] acts on piston top Upper generation maximum swelling power P [N], maximum swelling power P [N] act on generation tangential component T [N], tangential component T on crank-pin [N] generates torque M=TR [Nm] (R --- crank throw) to crankshaft center, pushes crankshaft rotation, exports effective power.

Since internal combustion engine indicated work (mechanical work of linear motion) has the above conversion and transmission process, so internal combustion engine The efficiency of indicated horsepower (mechanical output of linear motion) will be influenced by crank link mechanism transmission efficiency.

Over more than 100 years, the related theory of thermodynamics all assumes that working medium in reversal condition when studying thermodynamic cycle process Under convert heat energy into the expansion work (mechanical work) of linear motion, expansion work (mechanical work) is linear motion, determines machine driving Efficiency is that 1 (in the case where not considering mechanical friction loss) is correct.

Since having invented internal combustion type crank link mechanism engine, the Principles of Internal-Combustion Engine based on thermodynamics have been founded, Principles of Internal-Combustion Engine are for following 2 problems: 1. crank link mechanism is by the direction of transfer of expansion work (mechanical work) by moving along a straight line Change into the transmission efficiency of rotary motion.2. influence of the crank link mechanism to engine performance index, does not carry out theoretical research. Working medium is theoretically also assumed that under reversal condition, the expansion work (mechanical work) of linear motion is converted heat energy into, passes through song Handle link mechanism output mechanical energy determines that the transmission efficiency of crank link mechanism is 1, carries out internal combustion engine Ideal Cycle, burned The research of journey and the calculating (such as indicated horsepower, effective power) of correlation formula.

Author thinks: it 1 is incorrect that Principles of Internal-Combustion Engine, which determine that crank link mechanism transmission efficiency is,.By counting herein It calculates, crank link mechanism transmission efficiency is 0.7 or so (when P is constant).

When calculating combustion engine mechanical efficiency, due to testing effective power and indicated horsepower not under identical conditions (from reason By analysis, it is ensured that test is extremely difficult under identical conditions), the maximum generated for crank link mechanism transmission efficiency The loss of linear motion mechanical work 30% or so can not obtain.Principles of Internal-Combustion Engine are left by maximum linear movable machinery function 30% Right loss determines in expansion-loss, just forms that combustion engine mechanical is high-efficient, and waste gas loss is big, and the thermal efficiency is low, and this is abnormal Conclusion.Its essence is do not consider crank link mechanism transmission efficiency to caused by engine performance index due to Principles of Internal-Combustion Engine Influence.

Analyzed according to theory of mechanics: crank link mechanism is the carrier that thermal energy is converted to mechanical energy, crank link mechanism Transmission efficiency is 70% or so (P is constant), and 30% or so of maximum linear movable machinery function will lose in piston, cylinder, cylinder Body and crank link mechanism cannot be converted to mechanical energy, and the mechanical loss power that existing crank link mechanism starts is in 10- 30%, so actual machine efficiency=crank link mechanism transmission efficiency-mechanical loss work of crank link mechanism engine Rate=70%- (10- 30%)=40-60%.

5, the effective thermal efficiency of crank link mechanism engine

The effective thermal efficiency of crank link mechanism engine is influenced by combustion process, crank link mechanism mechanical efficiency, So the effective thermal efficiency of crank link mechanism engine 40% or so (because the influence of loss, the detonating combustion of combustion process, The variation of P).

Crank link mechanism air compressor machine

Crank link mechanism air compressor machine, compressor, compressor, hydraulic oil pump, hydraulic motor in existing machinery product etc., It is all that intake and exhaust valves are adapted as intake valve and exhaust valve, are incited somebody to action to wear body using the kinetic characteristic of crank Lian Ji mechanism Flywheel is changed to belt pulley, moves belt pulley rotary motion by motor generation, generates high pressure by the linear reciprocating motion of connecting rod, piston Gas.Belt pulley rotates a circle piston linear reciprocating motion one working cycles of secondary completion.

Aero gas turbine engine

Institution of higher education's education is dedicated, and Tsinghua University thermal technology teaches study group to compile, and People's Education Publishing House's nineteen sixty publishes " thermal technology Learn " page 335 have following discussion:

Jet engine construction is introduced

In the field of Modern High-Speed airmanship, jet engine has unrivaled superiority.Second of the world Since Great War, jet power is developed by leaps and bounds, and is not only a revolution on military technology, is also resulted in terms of civil aviation Variation sharply.

Jet engine is the energy heats air using fuel to obtain pressure high temperature hot gas, is allowed to produce by jet pipe Raw high-speed flow, the power to be advanced using the reaction force of jet-impingement as aircraft.

Jet engine has " punching type " and " turbine formula " two kinds of patterns.It is described below respectively now:

One, punching type

When studying steam turbine and gas turbine, the effect of jet pipe was once taught, the thermal energy of working medium can be by it Kinetic energy.After high pressure gas passes through jet pipe, pressure reduction, speed increases.In contrast, high-speed flow is such as poured into one end, in pipe It is interior since flow velocity reduces, kinetic energy will be transformed into potential energy, and then the other end will obtain compressed gas.It can be seen that jet pipe exists A booster apparatus can be become in counteractive situation, be called " diffuser pipe ".

The simple structure of athodyd is as shown in Figure 13-10 (see attached drawing 11).Its front is a diffuser pipe 2. aboard by the installation of such engine, when aircraft flight, the air in front is with very big relative velocity along the side of arrow 1 To pouring in diffuser pipe, so that it may in the exit of diffuser pipe, higher pressure is also generated in the entrance of youth combustion chamber 4.Spray Oil nozzle 3 sprays into fuel, and fuel sprays, and aircraft is made to advance by reaction.

The construction of athodyd is really comparatively simple.Figure 13-11 (see attached drawing 12) is with this engine work The cross-sectional view of the testing aeroplane of work.

The great advantage of athodyd be it is light, great function can be issued under the machine weight of very little Rate.If flying speed reaches twice of velocity of sound or more, its weight/power ratio can be less than 0.01 kilogram/thrust horse power.Due to machine Part is simple, and manufacture and repairing are all easy to.In addition, because it does not have rotating part, therefore do not need to lubricate.And flying speed Not by force by parts.But the oil consumption of this engine is very big, under 2000 kilometers/hour of speed, power pushes away horse for 60000 The athodyd of power, oil consumption are up to 4 Kilograms Per Seconds unexpectedly.Therefore economically apparently, athodyd exists Also it is not suitable for the application of skycoach at present.In addition, there are one important disadvantages for this engine, it is exactly that it has to When the air of aircraft forward pours diffuser pipe with sufficiently high speed, it could start to work.Therefore it cannot voluntarily take off, and install The aircraft of this engine must be taken off with airscrew engine or the help of the strength of rocket.

Due to above-mentioned disadvantage, athodyd does not obtain extensive use yet so far.Jet practical at present Formula aircraft, the overwhelming majority all use following turbine formula jet engines.

Two, turbine formula

Ordinary higher learning school's Eleventh Five-Year Plan National planning teaching material, National Defense Industry Press publish, and Deng Ming writes " aircraft gas whirlpool Turbine principle and construction " the 4-5 pages of a book has following discussion.
