Description
Technical field
The present invention relates to a kind of muffler technology, especially a kind of more gas chamber mufflers of internal combustion engine.
Background technique
The effect of exhaust pipe is exactly that exhaust gas is discharged from combustion chamber of engine, and the exhaust of engine is former due to the work of engine
Reason, the blast of exhaust is the discharge of one rolling land of a wave, if the diameter of exhaust pipe is smaller, each wave of discharge blast all can
In the biggish pressure of exhaust pipe internal form, when this wave blast starts to discharge outward in exhaust pipe, to latter wave blast
It just will form a negative pressure, that is, the back pressure described in everybody.The size of back pressure determines the best exhaust field of engine, such as
Fruit back pressure is bigger, engine the slow-speed of revolution blast due to being influenced by previous wave blast, will be faster by the negative of previous wave blast
Pressure is sucked out, that is to say, that exhaust effect is better, but when engine reaches high revolution, since the diameter of exhaust pipe is smaller, makes
At be exactly that next wave blast cannot be not only sucked out in pressure in exhaust pipe as early as possible, phase is caused to the discharge of each wave instead
When resistance, and interact between each wave blast, cause exhaust not smoothly, to reduce the performance of engine, this
When, select the exhaust pipe being relatively large in diameter that will play preferable effect.Advantage: noise is small, low speed torsion is good；Disadvantage: high speed
When exhaust gas can not quickly be discharged, influence engine power output.
What back pressure referred to is exactly, when gas advances, while the pressure caused by backside gas.The exhaust of engine is done,
Be not by once, be by the intensive very high gas of density again and again, allow front air mass and the air mass at rear it
Between formed negative pressure state.If the distance of front and back air mass is appropriate, that intermediate negative pressure will attract gas next time at once
Group forms the strength toward Anterior crossbite, the most smooth, the most ultimate attainment benefit for allowing the force production of engine to play of this linking
Back pressure appropriate must be leaned on.
On the contrary, causing the distance of front and back air mass too close if back pressure is insufficient.That reforms into front gas and can hinder
The advance of backside gas can be vented hindering mutually because of gas for upper relativity in this way, and back pressure is excessive, and engine is caused to export
The obstruction in face.
Full back pressure exhaust pipe: the volume variation of panel muffler or pipe mainly in tube a kind of can return to generate
The pressure of cylinder, after engine ignition, piston starts diameter action force-stroke, and exhaust valve can reach before the bottom dead center just in piston
It can open.At this moment, the back pressure in pipe can block exhaust gas and go out, and allow gaseous mixture that can reach completely burned.But back pressure is too strong, can make
It can not be completely exhausted out cylinder at exhaust gas, exhaust gas and one combust of gaseous mixture is caused to reduce efficiency of combustion.Certainly most directly it is exactly
Influence horsepower output.Advantage: noise is small, and low speed torsion is good；Disadvantage: exhaust gas can not quickly be discharged when high speed, influence engine power
Output；Volume: low.
Half back pressure exhaust pipe: the strength of this pipe back pressure is lower, and the compliance of exhaust is run well than back pressure.Briefly, it is
Between back pressure pipe and straight pipe, have appropriate back pressure to obtain starting torsion, exhaust compliance than back pressure Guan Jia, it is middle high to turn
Fast torsion is also bigger than back pressure pipe.Advantage: tail speed torsion is performed well in rising；Disadvantage: noise is bigger than normal, and volume is larger.
ZL200980161153. 1 exhaust apparatus for describing a kind of internal combustion engine, which, which has, is formed as hollow

Inside part constitute inlet duct portion be inserted through the insertion hole.The inlet duct portion is incorporated in expansion chambers and resonant chamber,
And supported by end plate and demarcation plate, the downstream open end as downstream open end is open in resonant chamber.Also, in inlet duct portion
It is upper, be formed with multiple apertures in the extending direction (discharge directions of exhaust gas) and circumferential direction of inlet duct portion, inlet duct portion it is interior
Portion is connected to expansion chambers via aperture.Thus, the inlet duct portion through central tube is directed to the exhaust gas of silencer, via aperture quilt
Expansion chambers are imported into, and are directed to resonant chamber from the downstream open end of inlet duct portion.In turn, for being directed to resonant chamber
Exhaust gas, the exhaust sound of specific frequency is eliminated using Helmholtz's sympathetic response.By reducing the volume V of resonant chamber, shortening entrance
The length Lp of the protrusion of the pipe portion or sectional area S for increasing inlet duct portion can tune resonance frequency towards high frequency side.
ZL200980161153. 1 passes through the length Lp for increasing the volume V of resonant chamber, lengthening the protrusion of inlet duct portion
Or reduce the sectional area S of inlet duct portion, resonance frequency can be tuned towards lower frequency side.But the exhaust apparatus of the internal combustion engine
As other same devices, although resonate small, low noise, when having the drawback that the one, slow-speed of revolution, nothing in middling speed
Method realizes large torque work, and large torque will appear insufficient pressure when working and torque reduces；Two, when high revolving speed, exhaust is unsmooth,
Limit maximum power；If three, applied in single-cylinder engine, it may appear that fry phenomenon in particularly apparent return-air, i.e., in difference
Stroke between and engine when reducing revolving speed suddenly, return-air phenomenon is obvious, and it is existing that muffler or internal combustion engine will appear implosion
As.
Muffler issues explosive sound, is commonly called as muffler explosion, muffler explosion is because the combustion mixture of unburned burning-out exists
The explosive sound that sending is rekindled in silencer is often accompanied by Mars and emerges, also referred to as blows out.Muffler explosion will lead to engine work
It is excessively high to make temperature, accelerating ability difference and traveling are powerless.Its reason just includes gaseous mixture overrich, the combustion mixture of engine due to
Overrich and fail completely burned, be discharged with exhaust gas, encountered in silencer fresh air burn again issue explosive sound.It is flammable
The phenomenon that gaseous mixture overrich causes muffler explosion, in time of engine low speed, sound is heavy and unstable；High engine speeds
When operating, muffler explosion is clearly better.
