It is a relatively rare occurrence for a car to suddenly stall while driving, but if it does, it can undoubtedly be frightening and confusing. Especially when the car is fast and there are many vehicles, this situation can pose a greater danger. Cars, unlike electric cars, can't be fixed by pushing, so it's quite a tricky problem. So, what's going on with a car that suddenly turns off while driving?
Waiting for a red light at an intersection suddenly turns off the engine and can't move, and the vehicles behind are still urging, which is an embarrassing situation that every driver may encounter. When this happens, you should first check the engine for carbon build-up, if you need to clean the throttle, then check if the idle motor is stuck, and finally check the gasoline pump. Sudden flameout is often caused by poor oil circuits, oil breaks, or fire breaks. Therefore, we should clean the idle motor and other components, pay more attention to the maintenance of the vehicle at ordinary times, and regularly overhaul the vehicle.
Another reason that can cause a car to suddenly stall is that the ignition system is not working properly. Problems such as long use of spark plugs, incorrect ignition, poor contact of ignition coils or inter-turn short circuit in the hot state may lead to problems such as the failure of high-voltage sparks or weak sparks, poor contact of low-voltage lines, damage of insulating glue, and poor intermittent and poor ironing. In this case, we should pay attention to replacing the spark plug and ignition wire, and check the relevant parts for repair.
In addition, a broken timing belt is also a common cause of sudden stalling of a car. The timing belt controls the coordination of the piston and valve, so that when the piston is in the proper position, the valve can be opened or closed, so as to ensure the normal operation of the engine. When the timing belt is broken, the work of the piston and valve becomes chaotic, which may cause the valve to open exactly when the piston rises, which leads to the collision of the piston and valve, causing more serious damage.
In addition, faulty electronic components can also cause the car to suddenly stall. For example, the engine computer is the core that controls all the operations on the vehicle, and once the engine computer fails, it will not be able to give any signals or commands, causing many other parts to not work properly and eventually causing the car to stall.
Fuel supply failures are also a common cause of sudden stalling of a car. Generally speaking, gasoline pumps have a long lifespan, so damage generally occurs on older vehicles. Some vehicles even have a gasoline pump failure when parked, resulting in a failure to ignite. While other vehicles are driving, there is a fuel supply failure.
When we find that the car suddenly stops, depending on the road conditions at the time, if there is no emergency, we can slowly apply the brakes to prevent being rear-ended by the vehicle behind. When the speed of the vehicle is reduced, slow down and drive towards the side lane. It should be noted that the brake should be stepped on all the time, and the force should be gradually increased, do not step on it and release it, and you will find that you cannot brake when you step on it again. When the vehicle is safely parked on the side of the road, turn on the four-flashing lights, place the warning triangle, and call ** for rescue tow truck.
The reasons why a car suddenly stalls while driving can be varied, including poor oil circuits, ignition system failures, timing belt breaks, electronic component failures, and fuel supply failures, among others. When this happens, we should check and repair the relevant parts in time, and at the same time pay attention to safety during the handling process to avoid accidents. At the same time, regular maintenance and overhaul of the vehicle can effectively prevent the occurrence of sudden shutdown and improve driving safety.
