Use And Maintenance Of Motorcycle Muffler

Motorcycle muffler is a device to control the exhaust flow noise of engine. Its function is to allow the air flow to pass normally and reduce the radiated noise energy. The exhaust of motorcycle engine has strong air flow pulsation noise. The exhaust port is equipped with a muffler, which can effectively reduce the air flow noise, so as to reduce the interference to the environment and increase the comfort of riders. However, after the muffler is used for a period of time, the effect will become poor. This paper will introduce some methods of muffler use and maintenance.

Avoid idling the accelerator and stalling

The motorcycle muffler is equipped with catalyst. If the unburned fuel enters the muffler, it will gather in the catalyst honeycomb and be ignited by the exhaust gas, which will make its temperature rise sharply. When it exceeds the allowable maximum temperature (1200 ℃), the metal honeycomb will be ablated, fallen off or melted.

In order to avoid the above situations, such as fuel sliding and flameout, the muffler must be avoided as far as possible.

Go to a regular gas station to refuel, and don’t add oil to the muffler

The pore diameter of the catalyst in the motorcycle muffler is 200 or 300 mesh, which is thinner than the 100 mesh catalyst installed in the motorcycle muffler before and easier to be blocked. If the impurity content in the gasoline used exceeds the standard or add oil to the muffler, the catalyst will be blocked. For this reason, please use the gasoline from the regular gas station, and do not add oil to the muffler.

Ensure that there is no combustion inside the muffler and good external heat dissipation

The muffler with black paint on its surface will fade or even turn gray white under high temperature. In order to avoid the discoloration of the muffler, the internal combustion of the muffler shall not occur and the external heat dissipation shall be good. The specific measures are as follows: do not drive for a long time with the choke closed; It is not allowed to empty the throttle for a long time; Windshields or other decorative items shall not be installed in front of the engine and muffler; Do not drive with heavy load and low gear for a long time.

In addition, the composition of the paint will change at high temperature, forming some holes in the micro. SiO2, such as clay, infiltrates into the micropores and is sintered with the paint at high temperature, which is difficult to clean. In order to avoid this phenomenon, when there are a lot of oil, soil and other stains on the surface of the muffler, it shall be cleaned in time.

Prevent the muffler from rusting

The key is to prevent water from entering the muffler. In winter or wet weather and car washing, it is necessary to prevent the increase of condensate or water from entering the muffler. After water is found, start the engine and warm up the vehicle at idle speed for at least 10 minutes; Drain the accumulated water inside as much as possible.

The service life of the motorcycle should not be prolonged by starting the muffler every long time.

Prevent the muffler from discoloration

When the cold vehicle is difficult to start in winter, close the choke and start the engine. After the hot vehicle, pay attention to open the choke in time. It is forbidden to drive at high speed for a long time when the choke is closed.

It is forbidden to install windshields or other decorative items in front of the engine and muffler, which will affect the heat dissipation of the engine and muffler.

Don't drive with heavy load and low gear for a long time, which will damage the engine and muffler. Do not slam the accelerator in place for a long time. When there is oil stain on the muffler surface; The surface color will turn yellow after hot driving. Blue.

When a large amount of dirt such as soil is stuck on the surface of the muffler, it shall be cleaned in time to avoid affecting its heat dissipation. When disassembling the muffler. Pay attention to whether the muffler is installed in place and fastened to prevent air leakage, so as not to affect the silencing effect and cause yellowing at the muffler interface.
