Some minor faults of the car can also be avoided in advance

Old drivers all know one sentence: 'Look at the six roads and listen to all directions', which means to listen and see more when driving. But do you know that when driving, you should not only look at the road conditions, but also develop the habit of observing the condition of the car. As long as you are careful to find out, some minor faults of your car can also be avoided in advance. The explosive force of the vehicle drops, the acceleration is weak, the noise becomes louder, the exhaust pipe has blue smoke discharge, and it is accompanied by the Coke smell generated by the combustion of oil. It is reported that by checking the oil gauge of the machine, it will also be found that the oil consumption is large. Under normal circumstances, after each maintenance, the oil consumption should be within the normal range after driving 5000 kilometers, and there is no need to supplement it halfway. Blue smoke is mostly caused by internal failure of the engine, causing the engine oil to jump into the combustion chamber. There are generally two common situations: one is serious wear and tear. There are scratches on the inner wall of the cylinder, poor sealing of the piston or serious wear of the valve, which will produce gaps, and the oil that was originally responsible for lubrication will jump into the combustion chamber to participate in combustion through these gaps, the burning oil produces blue smoke when it is discharged outside the car. Second, excessive oil filling can easily lead to oil burning. Some car owners mistakenly believe that the more oil they add, the better, but they do not know that excessive oil will also be brought into the cylinder for combustion, thus causing the phenomenon of burning oil. Excessive filling of oil will also block the normal operation of the crankshaft arm, allowing it to do additional work and increase energy consumption. For older vehicles, always check the tightness of cylinder block, piston and other parts, and go to the maintenance station to repair when blue smoke is found to be discharged to prevent greater losses; Oil should be added in an appropriate amount, too much or too little is not advisable; Regularly check the use of oil, once found abnormal oil consumption, immediately go to the professional repair station for inspection. Normal exhaust should be colorless and odorless, while automobile exhaust with different colors and tastes is likely to indicate that the vehicle itself is facing some faults. The engine is shaking, the exhaust pipe has abnormal sound, and the black smoke is discharged at the same time, and the acceleration feels weak. There are many reasons for the black smoke. If the carburetor car emits black smoke, the reason is more complicated. For example, when the spark plug does not work well during the cold start, it takes half a day to start the motor, so that the mixture accumulated in the cylinder cannot burn completely and naturally black smoke will be discharged; Or the vehicle ignition time is wrong, and black smoke will also be generated in advance or after the mistake. There is very little black smoke in the EFI car. If black smoke really comes out, it is mostly a fault in the cylinder. 'Broken cylinder' is a common one. Carburetor cars are basically old now. It is necessary to check the aging degree of carburetor and other parts. Carburetor cars are different from EFI cars. They should be maintained and adjusted frequently to develop good habits. The EFI vehicle should check the cylinder line every 30 thousand kilometers and the spark plug every 10 thousand kilometers. If there is any problem, it should be replaced in time. When you are on the car, it can be seen that a large amount of white water vapor is coming out and the engine is not running smoothly. Even if the engine is preheated to the normal working water temperature, there is still a large amount of water vapor coming out (Except Winter). The cause of white smoke may be due to the wear of the cylinder gasket of the engine cylinder, resulting in a certain gap, resulting in a large amount of water from the heat dissipation system entering the combustion chamber. Water cannot be burned, and water vapor is generated after being heated and discharged directly from the exhaust pipe. Reminder: Check whether the engine block and cylinder gasket are damaged, and check whether there is water in the oil tank. In addition, check the car instructions and add gasoline with the correct label in strict accordance with the manufacturer's regulations. In addition, a small amount of white exhaust gas will come out when the car is hot at low temperature, which is a normal phenomenon of hot and cold exchange, and the white smoke will naturally disappear after the car is hot.
