What is the engine energy-saving start-stop function?

Automatic engine start-stop means to automatically stop the engine when the vehicle stops temporarily. When it is necessary to continue, the system will automatically restart an engine system. English name stop &；; Start is short for STT.

STT intelligent fuel-saving system is a set of engine start-stop control system. It is a reinforced motor with idle start-stop function implanted in the traditional engine. When the vehicle meets the idle stop condition, the engine will completely turn off and not work.

When the whole vehicle needs to be restarted, the idle start-stop motor system quickly responds to the driver's starting instruction, quickly starts the engine, and instantly starts it, greatly reducing fuel consumption and exhaust emissions.

Extended data:

Engine energy-saving start-stop function technology appeared as early as the mid-1970s. At that time, Toyota actually tested this technology on the Crown Car. As long as the vehicle stops for 1.5 seconds, the engine will automatically cut off the oil and turn off the engine.

This has also become the embryonic form of the theory and design of automatic start-stop development in the future. This crown has been tested in Tokyo's urban traffic for a long time, which proves that this technology can bring about 10% fuel saving effect.

After that, many brands such as Volkswagen, Fiat and Citroen began to get involved in this technology, but it was not until 2006 that the automatic start-stop function began to become popular. The reason is that the increasingly strict regulations of the European Union force many automobile companies to find ways to save energy and reduce emissions.
