What is Auto Start-Stop?
2 Answers
Engine auto start-stop is a system that automatically shuts off the engine when the vehicle comes to a temporary stop (such as waiting at a red light) while driving. When it's time to move forward again, the system automatically restarts the engine. Below is an introduction to auto start-stop: 1. By equipping a traditional engine with an enhanced motor featuring idle start-stop functionality, the system completely turns off the engine when the vehicle meets idle stop conditions. When the vehicle needs to start moving again, the idle start-stop motor system quickly responds to the driver's command, rapidly restarting the engine for seamless transition, significantly reducing fuel consumption and exhaust emissions. 2. The STT intelligent fuel-saving system is a set of controls for engine start and stop. This system uses a computer to determine the vehicle's status, such as when stopped at a red light or in traffic congestion, and can automatically stop the engine. During the stop phase, it does not affect the use of in-car equipment like air conditioning or audio systems.
The auto start-stop system is like having a smart little butler in your car that immediately turns off the engine to save fuel when you stop. Its working principle is quite interesting: when you come to a stop at a red light and press the brake pedal firmly, the system uses sensors to detect that the car is stationary and shuts off the engine; when the light turns green and you release the brake, it can restart the engine within 0.5 seconds to get going. Behind the scenes, this is supported by a reinforced starter motor and a special battery, as regular components couldn't withstand the constant cycling. I've also looked into the activation conditions—it doesn't just shut off randomly. The engine coolant temperature must be right, the air conditioning shouldn't be at maximum, and the battery needs sufficient charge. At first, the repeated starts might feel a bit odd, but after six months, you can save up to 8% on fuel costs, which is especially noticeable in traffic jams.
