Exhaust pipe.
Exhaust pipe is a part of the engine exhaust system, exhaust system mainly includes exhaust manifold, exhaust pipe and silencer, generally for the control of engine pollutant emissions of the three-effect catalytic converter is also installed in the exhaust system, exhaust pipe generally includes the front exhaust pipe and the rear exhaust pipe.
Back pressure exhaust pipe
(and the original factory is more environmentally friendly) the same principle as the original factory, but the sound will be better than the original factory most of the original cars use this tube is mainly by the tube of the plate silencer or tube volume change to produce a pressure that will return to the cylinder, when the engine ignition, the piston began to track the power stroke, and the exhaust valve will be opened before the piston reaches the bottom dead point. At this time, the back pressure in the tube will block the exhaust gas out, so that the mixture can achieve complete combustion. However, if the back pressure is too strong, the exhaust gas can not be completely discharged from the cylinder, causing the exhaust gas to burn together with the mixture to reduce the combustion efficiency, of course, the most direct is to trigger the horsepower output. Its advantages: low noise, low speed torque. Disadvantages: Exhaust gas can not be quickly discharged at high speed, affecting the engine power output, low volume.
Half back pressure pipe
Of course, the strength of the pipe back pressure is low, the compliance of the exhaust gas is higher than the back pressure. Simply put, it is a moderate back pressure between the back pressure pipe and the straight pipe to achieve the starting torque. The compliance of the exhaust gas is better than the back pressure pipe, and of course, the torque of the medium and high speed is also larger than the back pressure pipe. Advantages: Good torque performance from the middle and tail speed Disadvantages: loud noise, large volume.
Straight pipe
Acceleration will be better than back pressure, but the biggest disadvantage is very noisy, noisy will let the "police uncle" to chase you back pressure is very low, exhaust no resistance, low speed torque is poor, medium and high speed torque is large. Advantages: smooth exhaust, high speed torque strong disadvantages: low speed soft force, loud noise (some people say that it is easy to burn out the valve do not know whether it is true) large volume.
Semi-straight pipe
In fact, the semi-straight pipe is the same as the half-back pressure pipe, but the exhaust diameter is bigger than the half-back pressure pipe: the starting torque is lower than the half-back, but the torque of the middle and high speed is large
Variable exhaust pipe
Exhaust is controlled through valves for optimal sound and performance.
S drum: Improve the low and medium speed torque, start fast. Strong climb. The sound is low, and the horsepower of high speed will not be sacrificed when it is about 90 decibels, mainly extending the formation of three wastes to achieve the role of power enhancement. (Disadvantage: there is resonance sound at high speed, and there is no much increase in horsepower at high speed), S drum is used for engines with displacement below 2.0.
Internal back pressure: specially designed according to the characteristics of its own car. Improve the low and medium speed torque, the sound is not noisy. No resonant sound. There is no resonance at high speed, and the speed is fast. (The sound is similar to the S drum, and some models cannot install the S drum, only the internal back pressure.)
Type G: For large displacement engines above 2.0, through 3 times of back pressure to reduce the effect of sound, extend the form of air flow. Similar to an S drum. The sound is around 90 decibels. Increase the torque of low and medium speed (S drum is used for small displacement vehicles below 2.0. G drum for large displacement vehicles above 2.0)
Straight row: Increase the horsepower at high speed, and the torque at low and medium speed will not be much improved. It is suitable for long time running at high speed and race track. The sound is around 100 decibels. It's noisy.
Y-type: Increase the torque at low and medium speed. The noise is loud. Around 95 decibels
Street Drum: Enhance horsepower and torque, the sound quality is also quite particular, the drum body is completely designed to increase horsepower and reduce the volume, it can be selected in the street and high-speed walking, the whole section of exhaust adopts the most popular Japanese gradually amplified design style, 47mm-63mm-76mm, 63mm and 76mm with back pressure pipe connection, more to play the potential of the engine, The sound is about 90 decibels, balancing the fuel consumption acceleration reaction, power improvement, and the street drum has become the ideal throat for street walking. (The street drum looks good, is baked black paint, and the car performance is very good.)
M drum: variable back pressure design, according to the speed of the level to adjust the size of the back pressure, at high speed, there is no resonance sound, when the engine at low speed, the gas flow speed is slow, the speed through the control valve will be slow, the vacuum suction is small, the storage of exhaust gas back pressure per unit time is large. When the engine is at high speed, the gas flow speed is fast, the speed through the regulating valve will be faster, the vacuum is large, the exhaust gas is eliminated, and the exhaust gas is smooth at high speed. To improve the torque at the same time also improve the effect of horsepower, (full speed power) high speed of about 85 decibels, is in the current domestic according to foreign design concepts to show the most obvious and power to improve the exhaust pipe, the sound is issued at 2500-3000 RPM, and the sound is quiet at 4000 RPM.
HKS type: It is in line to bring back pressure, improve the low and medium speed torque and high speed horsepower. The sound is smaller than the straight row, larger than the back pressure, more crisp, at 95 decibels never bother people. No resonant sound at high speed. (with the effect of Japanese HKS) Design principle: air flow along the wall.
Middle section: used to connect the head focus and the tail section, which also has the effect of increasing the horsepower by 3-4 pieces.
The design problem of exhaust pipe Angle of motor vehicle
The exhaust Angle of motor vehicle exhaust pipe is always a difficult problem for professional manufacturers to solve. According to the investigation, the Angle direction of the exhaust pipe of cars and light family cars is generally parallel to the ground, and the Angle of the exhaust pipe of high-power transport vehicles and agricultural vehicles is bent to the ground. From the point of view of environmental protection, according to the current motor vehicle exhaust pipe Angle direction design and mechanical design principle has not provided a new Angle direction design method. The optimal design scheme for the Angle direction of all vehicle exhaust emissions should be 180 degrees parallel to the ground and facing the rear of the vehicle. If the design scheme is not unified and standardized, the manufacturers will design the exhaust pipe discharge direction at will not conducive to environmental protection and accidental infringement incidents during driving.
1, the exhaust pipe Angle is about 45 degrees to the ground caused by unfavorable factors.
In this emission Angle range, when the car is running, the high flow rate of exhaust gas will blow up the dust on the ground, and the faster the driving speed, the greater the degree of pollution of the dust will be. At the same time, the greater the power of the car, the greater the gas flow and velocity of the emission, and the degree of pollution of the dust will be higher. According to market research, the most serious area of dust pollution should be along the highway, the more traffic, the more serious the dust. On the other hand, dust pollution is also related to the cleanliness of the road surface, and the more floating dust on the road surface, the greater the amount of dust blown by vehicle exhaust.
2. There are also certain problems with the Angle of the exhaust pipe bending to both sides of the car.
If the Angle of the exhaust pipe is turned to both sides of the car, the exhaust gas of the car will cause thermal shock injury to the pedestrian when driving. In addition, the automobile exhaust contains atomized oil stains that are not burned out, which includes pollutants such as sulfide and carbide, which will cause personal infringement to the human body.
3. When the Angle of the exhaust pipe is turned upward, serious damage will be caused to the vehicle body.
Car manufacturers generally do not choose this Angle. Because the sulfur, carbide and other pollutants in the exhaust gas will have a chemical corrosion effect on the metal parts such as the automobile body, manufacturers generally do not choose this exhaust emission Angle.
maintenance
method
1. When the cold car is difficult to start in winter, close the choke to start the engine, and pay attention to open the choke in time after the hot car. It is forbidden to drive at high speed for a long time with the choke closed.
2. It is prohibited to install windshields or other decorative items in front of the engine and muffler on riding vehicles (men's vehicles), which will affect the heat dissipation of the engine and muffler;
3. Do not drive for a long time at low gear with large load, which will cause damage to the engine and muffler;
4. Do not blast the accelerator at high speed in place for a long time;
5. When there is oil on the surface of the muffler, the hot car will make its surface color change yellow, blue and so on. In addition, when there is a lot of dirt and other dirt on the surface of the muffler, please clean it in time to avoid affecting its heat dissipation;
6. When installing the muffler, it should be noted that the muffler pad is installed in place and fastened to prevent air leakage, affecting the muffler effect and causing the muffler interface to yellow;
7. The engine valve clearance and carburetor, air filter, etc. should be adjusted and cleaned in a timely and correct manner according to the vehicle instructions, such as the valve clearance is too small or the mixture is too thick or too thin, which will affect the combustion and affect the muffler.
craftsmanship
Automobile exhaust pipe maintenance skill one: waterproof
When driving in rainy days or going to the car wash, we must pay attention to prevent the silencer from entering the water, otherwise it will easily lead to rust and affect the use of the exhaust pipe; If the muffler is not flooded, it is necessary to immediately start the engine hot car, and as much as possible, the water in the muffler is discharged, which is particularly important for the maintenance of the exhaust pipe.
Automobile exhaust pipe maintenance skills two: rust prevention
The anti-rust of the exhaust pipe of the car is not only waterproof, but also anti-rust, and the best way is to wipe some anti-rust oil, so that it can be more comprehensive. We first remove the muffler, block the drainage hole in the ground position, and then give the flange if the anti-rust oil, and then shake the muffler, until the anti-rust oil evenly enters the cylinder body, and then install the muffler. Then after the car travels about 20 kilometers, the blockage of the drainage hole can be taken away, and it can be done. The anti-rust maintenance of automobile exhaust pipe can be carried out about 2 times a year to greatly ensure that the exhaust pipe does not rust.
Automobile exhaust pipe maintenance skills three: clean
Because the exhaust pipe is often exposed, but it is the same as the interior of the car, if the interior of the exhaust pipe is covered with dirt, it will affect the normal use of the exhaust pipe, and may cause other harmful substances to enter the car due to the improper driving of the driver, and cause other bigger problems, it is also something that happens. Therefore, in the maintenance of the automobile exhaust pipe, we must also pay attention to the cleaning of the exhaust pipe.
