A few days ago I saw someone asking me what effect the deformation of the drive shaft has? In fact, many people know what the influence of the deformation of the transmission shaft is. If it is light, it will vibrate and make abnormal noises. The body will also be very strong. If it is heavy, the broken car will not be able to move forward, and even the car will be killed. Therefore, the influence of the deformation of the transmission shaft is still great.

The root cause: In this case, the car engine shakes more seriously, and sometimes the fault indicator flashes sometimes. Many people suspect that there is a product quality problem in the car. I think the real reason is that the cleaned gasoline and diesel caused the fuel supply to be interrupted, which may cause environmental pollution or blockage of the system software. At present, some excellent cars are equipped with an automobile exhaust gas detection system, because this type of automatic control system can very dexterously check the exhaust gas and gasoline and diesel cleaning situation, so the application of unclean gasoline and diesel will cause the supply and demand balance of gasoline and diesel, sparking 3. Environmental pollution of the exhaust system, resulting in diesel engine fault indicator lighting and different levels of engine jitter. Therefore, a reasonable solution is: after completely cleaning up the system software contaminated by the environment, continuously adding vehicle gasoline with stable index value characteristics and adding quantitative analysis of the fuel pipe cleaning fluid, the situation can be improved.

9. The temperature of the diesel engine is suddenly too high during operation: common fault judgment: true common fault. Root cause: If the car's coolant control machine quickly reaches the 100 ° C mark during the entire operation of the car, or when the car is started, the temperature of the engine coolant quickly rises to boil, and everything becomes normal after replenishing the coolant. However, the engine displacement is significantly reduced, indicating that the diesel engine mechanical structure is abnormal. Most of the reasons for this common failure are: serious water leakage in the water cooling system; the cylinder gasket blocking the water jacket and the cylinder is damaged; the main gate valve of the thermometer is dropped; the fan belt is loose or broken; the centrifugal water pump shaft and the centrifugal impeller are loose; the fan The clutch is not working well.

12. When turning, the turning of the steering wheel turns into a small turn, and the turning of the steering wheel turns into a small turn but turns into a turn: Common failure judgment: Really common failure. The root cause: The two conditions that arise when the transition is made are called insufficient transitions in the former, and excessive transitions in the latter, indicating that there is a problem with the steering system of the car. The driver feels that when the car turns to detour while accelerating: a car with insufficient turning characteristics will drive to the outside, and a car with too many turning characteristics will drive to the inside. When the driving half-time increases, it is called insufficient transition. When driving half an hour changes, it is called excessive turning. There is also a situation of this kind of transition. At the beginning, it was not enough to transition, but it turned into too many transitions halfway, and turned to the inside substantially. It is the most risky reversal situation and is prone to safety accidents. This situation occurs only in certain cars with built-in diesel engines.

42. It is safe to drive a car of the same well-known brand. Why do other people's cars burn less fuel, but their own cars burn more fuel: common fault judgment: false common faults. Root cause: First, the car consumes more residual oil on the uneven, steeply curved ground than on the vertical, open and smooth sliding friction ground; the car is more on the sand and the ground. Concrete and asphalt roads have more fuel consumption when traveling on the ground; vehicles traveling in the bustling area consume more fuel than traveling in the suburbs. The real-time road conditions in the bustling area are complicated, and the vehicles are often subject to traffic congestion. The speed is relatively low, and the relative real-time road conditions in the suburbs are good, and the vehicles can maintain the economic development rate. Second, you should always check the pressure change status of the cylinder, the working status of the ignition coil and the attitude of the gasoline and diesel system software. Whether the diesel engine has selected the ideal mixture gas concentration value and the appropriate ignition advance angle. This is all a decision car How much fuel consumption is important.

10. Accelerate the chance that the oil working pressure display lamp will illuminate: common fault judgment: true and false common faults coexist. The root cause: the oil lamp illuminates two conditions, real and false. To put it bluntly, it means that the working pressure of automobile oil is indeed low, and it is as low as the warning light from the indicator light, indicating that the intake system must be cleared due to common failures. To put it bluntly, it looks like a suspicion. There are no common failures in the automobile oil intake system, but the automobile oil working pressure indicator light system software has a common failure, which illuminates the indicator light incorrectly. Although such common faults are not easy to endanger the normal operation of the diesel engine, they should also immediately look for the root cause and eliminate them. In general, the probability of a serious illness is high, and it should be used as a key idea to distinguish common failures.
