After a car is used for a long time, various problems are inevitable, such as bad exhaust gases and high fuel consumption. So what is cause of smelly car exhaust and high fuel consumption? How can we solve this problem? Today editor is here to give you a good answer to this question.
Smelly exhaust and high fuel consumption in cars are mainly caused by following two reasons. The first reason is related to excessive carbon deposits in engine. Carbon deposits in automobile engines are colloids formed during incomplete combustion of an oil and gas mixture in a cylinder, which, after a long period of high temperature, form a black substance. When there is too much carbon in engine, it will not only cause difficulty starting car and high idle, but also increase fuel consumption of car, resulting in very harsh exhaust gases from car's tailpipe.
Therefore, everyone should clean engine from carbon deposits in time so as not to affect normal operation of car. When cleaning engine of carbon deposits, you can use hanging bottle method, which is not only more effective, but also saves time and effort.
The second reason for smelly exhaust and high fuel consumption of a car is failure of car's oxygen sensor. The car oxygen sensor is guardian of health of engine, it can always monitor oxygen content in exhaust. When oxygen sensor fails, engine computer cannot obtain information about oxygen concentration in exhaust pipe, as a result of which it cannot control concentration of mixture. This will not only increase fuel consumption and pollute car's exhaust, but also lead to unstable idling of engine. Therefore, when oxygen sensor fails, we must go to 4S store to replace it with a new one in time, and check if oxygen sensor is working normally every 30,000 kilometers.
After talking about problem of exhaust odor and high fuel consumption, editor will tell you about how to save fuel while driving. After all, price of oil is now relatively expensive, and it is worth saving a little. First of all, while driving, try to drive at a constant speed of "economic speed" and do not forget to accelerate sharply. The so-called "economic speed per hour" is most economical speed of car. The "economic speed per hour" of a typical car is in range of 60-90 km/h, and you just have to try to control it. at this speed.
Secondly, everyone should check their car's tire pressure before driving to make sure tire pressure is within normal range. If tire pressure is too low, it will increase contact area between tire and ground, increase friction, and also increase vehicle's fuel consumption. So everyone should not listen to so-called winter tires: lower pressure, more slippery tire.
Also, when you turn on air conditioner in winter, do not press air conditioner button. If you turn on A/C button, compressor will start working, which will increase car's fuel consumption. If window fogs up when you turn on heater, you can turn on A/C button for a while to prevent fogging, and then turn it off after fogging clears.
The above fuel saving tips are very practical, take a notepad and write them down~
