??In the history of motorcycle development, motorcycle muffler is an indispensable part, and its development history is as long as motorcycle. Due to the strict requirements on environmental protection, all kinds of cars have already turned to EFI system, and major car enterprises have even begun to sell new energy vehicles. The transformation of motorized "national four" is imperative. So let's first understand that some EFI system faults will inevitably occur after the vehicle has been used for a long time, which is also a normal phenomenon.

Automotive oxygen sensor should be familiar to everyone. It mainly plays the role of motorcycle muffler detection and feedback. It can effectively control exhaust emission, reduce vehicle pollution to the environment and improve the combustion quality of engine fuel. The importance of oxygen sensor is self-evident. Today we will popularize some of its knowledge.

What is the function of the oxygen sensor on the motorcycle muffler?

The oxygen sensors on cars and motorcycles are generally divided into front oxygen sensors and rear oxygen sensors. Due to their different work contents, their installation positions are also different. Nowadays, many cars have three-way catalysis devices. Generally, oxygen sensors are installed in front and back of three-way catalysis. This position determines their working nature, and it is more convenient to find them during maintenance.

Motorcycle muffler manufacturers have learned that the common faults of oxygen sensor are as follows. The first is the problem of crushing. Its ceramic material is brittle and hard, which is easy to fail due to crushing, which needs attention. If the gasoline or lubricant contains lead, the silica gel produced after combustion has a great impact on this, that is the reason for its poisoning. In addition, the broken resistance wire and broken wire will also make it invalid.

The oxygen sensor is a part of the exhaust system. The front oxygen sensor is mainly used to detect the oxygen content in the exhaust gas. The oxygen content represents the level of the mixture and is transmitted to the ECU through an electrical signal. Therefore, the ECU will correct it accordingly, so as to change the concentration of the mixture, so as to promote more sufficient combustion of the mixture and effectively reduce pollutant emission.

The rear oxygen sensor mainly detects the oxygen content of the tail gas after three-way Catalysis (we call it "catalyst"), and the ECU compares its data with the front oxygen sensor to judge whether the three-way catalyst works and whether the tail gas exceeds the standard.

Then the question comes, can the car drive if the rear oxygen sensor is broken? The answer is yes. Can you run at high speed? The answer is yes, because the oxygen sensor is only a function of detection and feedback, and it has no great impact on the driving of the whole vehicle. The existence of oxygen sensor is reasonable and may not be reflected in the short term, but with a long failure time, a series of problems will follow.

Because the oxygen sensor cannot feed back information to the ECU for a long time, the ECU can only work normally according to the previous data. Over time, problems such as increased carbon deposition, increased fuel consumption and substandard emission will often occur. Therefore, the oxygen sensor is broken and the oxygen sensor will not be replaced for a short time, so the oxygen sensor will not be replaced if it is broken.
