Recently, many car owners have responded that the truck suddenly becomes boring when driving. When encountering such a problem, it not only costs fuel but also delays things. What is the reason for the sudden boring of the vehicle? There are many factors that cause the power to weaken suddenly when the vehicle is driving. The following describes the most common faults that cause the power to deteriorate of suddenly boring.
The main function of diesel filter is to remove sundries in diesel and prevent blockage of common rail system, especially fuel injection nozzle. The good filtration of diesel can effectively reduce wear, ensure the stable operation of the engine and improve the reliability of the engine of suddenly boring.
The oil quality in some parts of China is relatively poor. When these diesel fuels are used for a long time, if the water or impurities in the diesel fuel are not filtered, they will wear and tear the plunger couple in the fuel injection nozzle and cause strain of suddenly boring.
Fuel injector damage will cause engine acceleration instability, weak acceleration, or emission of black smoke and other faults, affecting the normal operation of the vehicle of suddenly boring.
The valve is an important part of the engine. It is responsible for air input and exhaust emission, and detects whether the inlet valve clearance is too small. If the inlet valve clearance is too small, the engine air supply is insufficient, the fuel in the cylinder is insufficient, and the power becomes small. If the valve seal is poor or the clearance is too large, it is easy to cause pressure relief in the cylinder, which will also lead to the decline of vehicle power.
If there is a problem with the vehicle’s air intake system, first check whether the air pipe is broken or the interface is loose. If the air intake pipe leaks, the oxygen supply in the diesel engine cylinder is insufficient and the combustion is insufficient, the power will be reduced.
As the lung of the engine, the air filter plays a very important role. After the air filter is used for a period of time, the filter element will be covered with dust and the filtering capacity will be reduced, which is easy to lead to excessive mixture and abnormal engine operation and poor power performance. Pay attention to the daily cleaning and maintenance of the air filter, and replace it immediately when the filtering effect becomes worse.
Due to various factors, such as the use of inferior air filter and pipeline rupture, the interior of intercooler is very easy to become dirty and blocked, which has basically lost its use value.
There are many reasons for the sudden deterioration of the vehicle’s power during driving. Today, it is mainly introduced from the two aspects of the vehicle’s gas circuit and oil circuit. If the repair shop encounters such a problem, it can check these two aspects first, and then carry out professional repair, detection and maintenance.
