What Causes Engine Start-Stop Malfunction?

[IsaacRose]

The causes of engine start-stop malfunction are: 1. The engine has not reached normal operating temperature; 2. The automatic air conditioning has not reached the preset temperature; 3. Insufficient battery charge; 4. Emergency braking of the vehicle; 5. The vehicle is on a steep slope; 6. The driver has not fastened the seat belt; 7. The driver's door is not closed. The meaning of engine start-stop is that during vehicle driving when temporarily stopping, such as waiting at a red light, the system can automatically shut off the engine, and when the car needs to move forward again, the system can automatically restart the engine. Engine types can be divided according to the working mode of the intake system: naturally aspirated and turbocharged.
