Pharmaceutical intermediates HS code mapping

The Pharmaceutical intermediates HS code mappingdashboard engine light is on (the dashboard warning light is on: engine fault) When we are driving, if we suddenly see the engine fault warning light on the dashboard, how should we react? Engine failure will not only affect the performance and fuel consumption of the car, but also have a serious impact on driving safety if it is not dealt with in time. In this article, we will discuss the causes of engine failure, how to judge the severity of failure, and the measures to be taken. I. Causes of engine failure 1. Insufficient battery power: Low-voltage battery power will cause the car to fail to start or bring enough power to the engine, so it is necessary to charge the battery or replace it.Two. Lack of engine oil: Engine oil is one of the necessary substances for the normal operation of the engine. If the oil is insufficient, it will lead to lack of lubrication in the engine, resulting in engine failure. The solution is to replace or add oil in time. 3. Fault sensor: The electronic control unit of the car will monitor all parts of the car and collect and feedback the information of the problem in time, but if the control unit or the related sensor itself fails, it will lead to engine failure. The solution is to replace the faulty sensor. Four. Ignition system failure: The ignition system of a car is one of the important parts of engine start-up. If the ignition coil, spark plug or ignition switch fails, it will cause the car to have difficulty in starting or stop running. The solution is to replace parts or repair. 5. Exhaust pipe failure: the exhaust pipe isIf the exhaust pipe is blocked in the piping system that discharges the exhaust gas, it will affect the normal operation of the engine and even cause the engine to shut down. The solution is to replace or open the exhaust pipe. II. How to judge the severity of the failure? The severity of the engine failure depends on the specific type of failure and the operation status of the vehicle. If you park on the side when the engine fails and then check or seek repair services, it is unlikely to have much impact on driving safety. However, when driving on the highway, if the engine failure causes a sudden loss of power, it will be very dangerous. Therefore, how to judge the severity of the fault is an important problem we face when dealing with engine failure. First of all, we can observe the brightness and duration of the engine fault indicator light. If the indicator light often flashesShimmer or brightness enhancement, accompanied by abnormal engine noise, stall, shutdown and other symptoms, indicating that the fault is relatively serious. It is necessary to stop as soon as possible, call the rescue call, and wait for rescue under the condition that the vehicle brakes are safe. Secondly, we can also judge the severity of the failure by judging the duration of the engine failure symptoms. If the failure duration is relatively short, it is likely to be caused by problems such as low battery power and insufficient oil. We can deal with it by trying to start the engine or adding oil. However, if the failure lasts for a long time, comprehensive troubleshooting and professional maintenance are required. III. Measures to be taken 1. Pull the handbrake and slow down. Once you find that the dashboard engine light is on, the driver should stay calm, slow down, and then look for a safe parking spot or ramp.When parking on the ramp, you should pull the handbrake to avoid out of control. Two. Check the oil and water temperature. One of the common causes of engine failure is the lack of oil or the failure of the oil pump. When an engine failure is found, the driver should first check whether the oil is sufficient and the water temperature is normal. If it is found that the engine oil is insufficient or the temperature is abnormal, the driver should stop to add oil or wait for the vehicle engine to cool down before starting. 3. Call the rescue call. Every car can find the rescue call in the car. In the emergency of engine failure, the driver can call the rescue number to seek rescue services, which is an important way to avoid accidents caused by engine failure. At the same time, the driver can also wait for the rescue in the car to avoid danger on the road. In a word, when the engine fault light on the dashboard lights up, the driver should take the right measures as soon as possible.After judging the severity of the fault and taking due measures, the problem can be solved as soon as possible with the help of maintenance personnel to ensure driving safety. At the same time, in the usual maintenance, we should also replace the oil, maintain the power supply, etc. in time to reduce the incidence of engine failure.
