What is the meaning of auto start-stop?
1 Answers
The auto start-stop system in vehicles refers to a system that automatically controls engine shutdown and ignition. When the vehicle comes to a temporary stop during driving, the engine automatically goes into a dormant state. This is mainly applicable in urban traffic situations such as waiting at traffic lights or during traffic congestion. For automatic transmission vehicles, once the car is started, the auto start-stop system is in normal working condition. When encountering a traffic light or stopping for other reasons, pressing the brake pedal will generally cause the engine to automatically shut down after two seconds. To start moving again, simply release the brake and press the accelerator, or gently turn the steering wheel, and the engine will restart. For manual transmission vehicles, when stopping, shifting to neutral, pulling the handbrake, and releasing the clutch will prompt the system to automatically shut down the engine upon recognizing these three actions. When the clutch is pressed again, the engine will automatically restart. Vehicles equipped with engine start-stop technology also have their air conditioning systems replaced with electric air conditioning. When the engine stops, the battery continues to power the air conditioning system. The steering mechanism is also replaced with electric power steering, as hydraulic power steering requires the engine to provide hydraulic pressure. Precautions for using auto start-stop: When driving on steep slopes, it is advisable to avoid using the auto start-stop system. Although the auto start-stop duration is brief, engine start-stop on a slope may lead to insufficient brake assistance. When driving through water, it is best to turn off the start-stop system. This prevents the engine from shutting down when stopping during driving, which could cause a sudden reduction in exhaust pressure. Water could then easily flow back from the exhaust pipe into the engine, making it unable to start.
