A short while ago, i sent the vehicle for maintenance, and the mechanic opened the hood, pointing at a small part of it, and said, “your oxygen sensor has been working poorly, no wonder the fuel consumption has recently increased.” i was wondering, what was the use of this big slap device? After a conversation with the master, i finally realized that this small component was like a “tail gas monitor” hidden in the engine, which monitored the gas content of the exhaust all day, even more stringent than the staff who checked the health code at the door of the district. Think about it. Cars need not only fuel, but also a proper proportion of air. It's like cooking when it's too oily, when it's too oily, when it's too oily, when it's too oily, when it's too thin. An oxygen sensor is installed in an exhaust tube to continuously monitor the oxygen content of the tailings and, if an incorrect ratio is found, immediately sends a signal to the engine control unit: “there is too much fuel on this side to need to be reduced!” or “there is too much air to need more fuel!” through such regulation, engine combustion fuel is more efficient and pollutants in the tailings are naturally reduced。
A friend of mine, driving a manual vehicle, has recently complained about the lack of power of the vehicle and the frustration with its suspension. After detailed inspection at the repair plant, it was found that the oxygen sensor had been blocked by carbon accumulation. When the master removed the sensor, i saw a bright probe that was supposed to be covered with a dark layer of material, like an uncleaned pan. With the replacement of the new oxygen sensor, friends indicated that the driving experience of the vehicle was new, that it was lighter when it stepped on the gas, and that it had travelled dozens of kilometres with a tank full of oil。
Although the component was not visible, its working environment was extremely harsh. The high temperature in the exhaust pipe is sufficient to warm the eggs and is permanently eroded by a variety of exhaust gases, with some minor breakdowns inevitable over time. It's like people in the kitchen are long-smoking, and their faces are prone to pox. If there's a problem with this component, the vehicle's performance will be compromised. – the low speed can be severed, the slowness of reaction at acceleration and the rapid decline of the oil gauge. Worse still, exhaust emissions may exceed the standard at vehicle testing, which will cause many inconveniences。
Last winter, i drove to pick up people in the middle of the night and suddenly the engine failure light on the dashboard went off. At the time, there was a great deal of concern about whether the engine needed to be overhauled. The more unsettled i was, the more i pulled over and called a friend of the mechanics. After listening to my description on the phone, he told me not to be nervous, possibly because the oxygen sensor was frozen or affected by water vapour. He advised me to stop the engine and wait for a few minutes before it started. It was then checked and the sensor was damp and everything was normal. See, this little part is really sensitive。
One might say, whether or not the oxygen sensor is normal, as long as the car can drive. This view is not really true. If the oxygen sensor fails for a long time, the opportunity to initiate the continuous use of inappropriate hybrids will not only increase fuel consumption but also damage the tri-channel. The cost of replacing the tri-channel is considerable and at least several thousand dollars. This is as if there is a problem with the stomach if food that is not suitable is consumed for a long period of time, when the cost of medical treatment will be much higher than the cost of diet。
In day-to-day driving, the condition of the oxygen sensor can be judged by some subtle signs. For example, the same tank of oil, which has recently suddenly decreased the mileage; when the cold car starts, the engine is unstable and it takes a long time to return to normal; and the smell of the tail gas suddenly becomes stale and the smell is visible after standing in the car. In all these cases, the oxygen sensor is sending a “alarm” that you are advised to check your state in a timely manner。
It should not be neglected in maintenance. When the master removes the cleaning, you can ask more whether the probe is corrosive and whether the line interface is loose. Just as a medical examination requires not only a blood test but also an electrocardiogram, a thorough examination is required to ensure security. Generally, this component can use 560,000 kilometres, but the specific lifetime depends on the vehicle environment. Their useful lives may be reduced if they are often travelled in crowded areas or when fuel used is of poor quality。
Today's cars are getting smarter and interesting. In the past, all driving was carried out with the feeling that the oil was not properly matched and the fire was easily extinguished; today, cars are equipped with dozens of sensors that can send an immediate signal from any anomaly. An oxygen sensor, though deep, cannot be underestimated, not only as a vehicle's power, but also as a “heroes behind the scenes” of silent dedication to ensure that exhaust emissions meet the standards。
The purpose of driving the car was to save effort. More attention to these small components on a regular basis will enable vehicles to reduce their failure. After all, the car is like an old friend of ours, and you're nicer to it so it can take you further and more steadily。
Finally, if you feel that this is helpful, welcome and welcome. In the future, i may also be able to share more of my little car-use knowledge. I wish you all a good ride and a good wallet。
