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：At a high speed
When exhaust gas can not quickly be discharged, draw ring engine power output.

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：It is 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, there is appropriate back pressure to obtain starting torsion, is vented compliance than back pressure Guan Jia, middle high revolving speed
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.
