Description
Technical field
The present invention relates to a kind of baffler technology, particularly a kind of internal-combustion engine many air chambers muffler.
Background technique
The effect of outlet pipe is discharged waste gas exactly from combustion chamber of engine, the exhaust of engine is due to the working principle of motor, the blast of exhaust is that ripple one rolling land is discharged, if the diameter of outlet pipe is less, each ripple of so discharging blast all can at the larger pressure of outlet pipe internal form, when this ripple blast starts outwards to discharge in outlet pipe, a negative pressure will be formed to a rear ripple blast, namely everybody said back pressure.The size of back pressure determines the best exhaust field of engine, if back pressure is larger, engine at slow-revving blast due to by the impact of last ripple blast, will sooner by the negative pressure sucking-off of last ripple blast, that is exhaust effect is better, but when engine arrives high revolution, because the diameter of outlet pipe is less, what cause is exactly that pressure in outlet pipe not only can not next ripple blast of sucking-off as early as possible, on the contrary suitable resistance is caused to the discharge of each wave, and interact between each ripple blast, cause exhaust not smoothly, thus reduce the performance of engine, this time, the outlet pipe selecting diameter larger will play good effect.Advantage: noise is little, low speed torsion is good; Shortcoming: during high speed, waste gas cannot discharge fast, affect engine power output.
What back pressure referred to is exactly, time gas advances, simultaneously to the pressure that backside gas causes.The exhaust of engine is done, is not what accomplish without any letup, is by the very high gas of intensive density again and again, allows between front air mass and the air mass at rear and form negative pressure state.If the distance of front and back air mass is suitable, the negative pressure in the middle of that will attract air mass next time at once, and define the strength toward Anterior crossbite, this linking is the most smooth and easy, and the most ultimate attainment benefit allowing the force production of engine play must lean on suitable back pressure.
On the contrary, if back pressure is not enough, cause the distance of front and back air mass too close.That just becomes the advance that front gas Hui hinders backside gas, like this can in exhaust relativity because gas hinders mutually, back pressure is excessive, causes engine to export obstruction above.
Full back pressure outlet pipe: the lattice plate baffler mainly in tube or the volume-variation of pipe produce the pressure that a kind of meeting returns cylinder, when after engine ignition, piston starts footpath action edge stroke, and exhaust valve BBC will be able to be opened in piston arrives.At this moment, the back pressure in pipe can be blocked waste gas and go out, and allows mixed gas reach perfect combustion.But back pressure is excessively strong, waste gas can be caused cannot to discharge cylinder completely, cause waste gas to burn together with mixed gas reduction combustion efficiency.Certainly be exactly the most directly affect horsepower to export.Advantage: noise is little, low speed torsion is good; Shortcoming: during high speed, waste gas cannot be discharged fast, affects engine power and exports; Volume: low.
Half back pressure outlet pipe: the strength of this pipe back pressure is lower, and the compliance of exhaust is run well than back pressure.Briefly, be between back pressure pipe and straight-through tube, have the back pressure of appropriateness to obtain starting torsion, be vented compliance than back pressure Guan Jia, middle high rotating speed torsion is also large than back pressure pipe.Advantage: in rising, tail speed torsion is done well; Shortcoming: noise is bigger than normal, volume is larger.
ZL200980161153.1 describes a kind of venting gas appliance of internal-combustion engine, and this silencing apparatus possesses the shell being formed as hollow tube-shape; The end plate at the two ends of closure; And the demarcation strip be installed between end plate and end plate, shell, end plate and demarcation strip form muffler body.Enclosure is divided into by the demarcation strip be arranged in shell: expansion chamber and resonant chamber, and this expansion chamber is used for waste gas is expanded; Resonant chamber is for utilizing Helmholtz's sympathetic response to eliminate the exhaust sound of characteristic frequency.Further, form inserting hole respectively at end plate and demarcation strip, the inlet duct portion be made up of the part of the inside being incorporated in silencing apparatus in the end in the downstream side of central tube, i.e. central tube is inserted through this inserting hole.This inlet duct portion is incorporated in expansion chamber and resonant chamber, and is supported by end plate and demarcation strip, as the downstream open end of downstream open end at resonant chamber opening.Further, on inlet duct portion, at the bearing of trend (discharge directions of waste gas) of inlet duct portion and circumferential direction, be formed with multiple aperture, the inside of inlet duct portion is communicated with via aperture with expansion chamber.Thus, the inlet duct portion through central tube is directed to the waste gas of silencing apparatus, is directed to expansion chamber via aperture, and is directed to resonant chamber from the downstream open end of inlet duct portion.And then, for the waste gas being directed to resonant chamber, utilize Helmholtz's sympathetic response to eliminate the exhaust sound of characteristic frequency.By reducing the sectional area S of the volume V of resonant chamber, the length Lp shortening the projection of inlet duct portion or increase inlet duct portion, can be tuning towards high frequency side by resonance frequency.
ZL200980161153.1, can be tuning towards lower frequency side by resonance frequency by increasing the sectional area S of the volume V of resonant chamber, the length Lp lengthening the projection of inlet duct portion or reduction inlet duct portion.But the venting gas appliance of this internal-combustion engine is the same with other same devices, although when middling speed, resonate little, noise is low, has following shortcoming: one, during the slow-speed of revolution, cannot realize high pulling torque work, there will be meeting underpressure and moment of torsion reduces during high pulling torque work; Two, during high rotating speed, exhaust is not smooth, limits peak output; If three are applied in single-cylinder engine, there will be the interior fried phenomenon of especially significantly return-air, namely between different strokes, and when motor reduces suddenly rotating speed, return-air phenomenon is obvious, and baffler or internal-combustion engine there will be implosion phenomenon.
Baffler sends explosive sound, is commonly called as muffler explosion, and muffler explosion is because the inflammable mixture that unburned is complete rekindles the explosive sound sent in silencing apparatus, often emerges with Mars, also claims to blow out.Muffler explosion can cause engine operating temperature too high, and acceleration performance is poor and travel unable.Its reason just comprises mixed gas overrich, and the inflammable mixture of motor fails perfect combustion due to overrich, discharge with waste gas, runs into fresh air and burn again and send explosive sound in silencing apparatus.Inflammable mixture overrich causes the phenomenon of muffler explosion, and when time of engine low speed, sound is heavy and unstable; During high engine speeds running, muffler explosion is clearly better.
