If there is blue smoke from the engine, it means that there is a problem with the engine. So, how can we judge whether it needs to be overhauled? This article will analyze from the following aspects.I. The reason why the engine has blue smoke. First of all, we need to know the reason why the engine has blue smoke, so that we can better judge whether it needs to be overhauled. Several common reasons are as follows: 1. The oil has entered the cylinder. If you can feel a pungent smell of oil at the same time when the engine is emitting blue smoke, it means that the oil has entered the cylinder, causing the smoke to turn blue. At this time, it is necessary to change the oil in time and check whether the engine sealing and cylinder pad are damaged. Two. Insufficient combustion of the engine. If the carbon accumulation of the engine is serious, it will lead to insufficient combustion and blue smoke from the engine. At this time, it is necessary to clean and maintain the engine, as well as replace the parts with severe carbon accumulation in time. 3. The mechanical parts of the engine are damaged or aging. If the mechanical parts of the car engine are damaged or aged, it will cause the engine to not work properly or even fail.At this time, it is necessary to replace the faulty parts and check other parts to ensure the normal operation of the engine. II. How to judge whether the car needs to be overhauled and repaired? First of all, we need to analyze the cause of the blue smoke in the engine. If the blue smoke is caused by the oil entering the cylinder, it needs to be observed for a period of time after replacing the oil. If the blue smoke returns to normal, there is no need for overhaul. If it is blue smoke caused by damage to the mechanical parts of the engine, it needs to be more rigorously overhauled, and the corresponding technicians need to check and repair. If it is a problem caused by insufficient combustion of the engine, you can consider engine maintenance and cleaning to return to normal operation. III. The importance of car maintenance. Cars are an indispensable transportation in our lives.It is one of the tools, but in the process of daily use, the car must maintain a good technical state in order to play the greatest role. At the same time, the maintenance of the car is also very important. Only through regular maintenance and upkeep can the performance and life of the car be ensured. At ordinary times, we must pay attention to the timely maintenance of the car, and check and replace the oil, filter and other important parts of the car in time to ensure the normal operation of the car. At the same time, doing a good job of daily car cleaning and disinfection can effectively avoid the corrosion and damage caused by dust, rainwater and other pollutants. In a word, if your car engine has blue smoke, you don't have to send it for repair quickly. You need to analyze the cause of the blue smoke first, and judge and maintain it according to the actual situation. In the process of daily use, we also need to strengthen the daily maintenance of the car to ensure that the car always maintains a normal working state.
