Many customers will say that their cars were originally good. The synchronous chip seal vehicle suddenly lost power while driving. Once encountering such a problem, it will not only waste fuel, but also delay the journey. Old drivers who know cars can sometimes solve it by themselves, while some drivers who don’t know can only make do with running the whole journey and then find a repair shop for repair. What exactly caused the vehicle to suddenly lose power!
There are many factors that cause the power of the vehicle to suddenly weaken during driving, but the common reasons are mainly the following. Here are some common faults that cause power deterioration and ways to solve them by yourself.
1. Insufficient air supply and incomplete combustion of fuel in the cylinder

Solution: Problems with the vehicle’s intake system are a major reason for the sudden deterioration of the vehicle’s power. We can check along the intake system to find out where the fault has caused insufficient engine air supply, resulting in incomplete combustion of fuel in the cylinder, causing the truck’s power to suddenly deteriorate. First, check whether the air pipe is broken or the interface is loose and leaking. If the intake pipe leaks, the diesel engine cylinder will be insufficiently supplied with oxygen, and the combustion will be incomplete, and the power will become smaller. Check the leaking position. If it is loose, you can tighten the lower interface by yourself. If it is broken and the crack is relatively small, you can use tape to stick it first, and then find a professional repair shop to replace it. The air filter is the lung of the engine, and its role is very important. After the air filter is used for a period of time, the filter element will be covered with dust in the air, the filtering capacity will decrease, and the air circulation will be hindered, which will easily cause the mixture to be too rich, causing the engine to work abnormally and the power performance to deteriorate. Pay attention to the cleaning and maintenance of the air filter on a daily basis.
2. Problems with the supercharger
Nowadays, whether it is a diesel engine or a gasoline engine, more and more attention is paid to the use of the supercharger. The supercharger can increase the intake pressure, increase the engine's intake volume, make the fuel burn more fully, and thus increase the engine's power. If there is a problem with the supercharger, the engine's air supply will decrease, and the power will also decrease. The supercharger is often in a high-temperature and high-temperature working environment. You must pay attention to these 3 problems in daily use:
1. Do not start the car when it is cold.
2. Do not turn off the engine immediately after driving.
3. The engine oil and filter must be genuine.
3. Small valve clearance or poor sealing, insufficient air supply and pressure relief in the cylinder
The valve is an important part of the engine, responsible for the input of air and the discharge of exhaust gas. Check whether the clearance of the intake valve is too small. If the clearance of the intake valve is too small, the engine will not be able to supply enough air, the fuel in the cylinder will be insufficient, and the power will be reduced. If the cylinder seal is poor or the clearance is too large, it is easy to cause pressure relief in the cylinder, which will also cause the vehicle's power to decline.
