What to do if a new energy vehicle suddenly stalls? The biggest safety hazard of sudden stalling while driving is “brake failure”, so safety intervention should be carried out in time. The emergency treatment methods are as follows: Control the direction well If the car suddenly stalls while driving, you must control the steering wheel of the car and try to keep the car stable, because once the car engine is turned off, the steering power will be lost, the steering wheel will be very heavy, and you need to use force to control the direction.
Restarting the car Manual transmission models can shift the gear lever to the appropriate gear according to the speed, and then step on the clutch to restart the engine; automatic transmission models can shift the gear lever to N gear, then restart the engine, and then push it into D gear.
Emergency braking If the car cannot be restarted, turn on the double flash immediately, and control the car to drive to the right and then stop steadily. After the engine is turned off, the brake hydraulic pump will also stop working, and the brake may not be able to be stepped on after one foot, so this foot brake is very critical. You can use the gear to slow down first, and then step on the brake when you encounter the right opportunity.
After contacting rescue and parking, observe the situation outside the car before opening the door, and place warning signs as required. Contact the 4S shop or repair shop for assistance.
Reasons for sudden flameout of manufactured cars
There are usually three reasons: circuit failure, oil circuit failure, and mechanical failure.
The fault point of circuit failure is usually the electrical components or circuits such as the ignition coil, ignition module, crankshaft position sensor, and engine control unit. The fault phenomenon is usually that the engine can be restarted after being turned off, but it is not certain when the fault will reappear. In actual maintenance, the most common cause of sudden flameout is the failure of the fuel pump control unit and the ignition coil.
Oil circuit failure is usually caused by damage to the fuel pump, resulting in failure to pump oil. The life of the fuel pump is relatively long. The faulty car is generally a car that has been used for a long time, or a vehicle that has not replaced the fuel filter for a long time. If the fuel filter has not been replaced for a long time, the fuel pump will be overloaded, resulting in a shortened service life.
Timing belt breakage The timing belt is used for transmission between the crankshaft and the camshaft, controlling the coordination between the piston and the valve, such as when the piston is in what position the valve should be open or closed. If the timing belt is not replaced according to the prescribed mileage, it may break, and the piston and valve may collide, causing the engine to stall.
