How much do you know about the intelligent fuel saving STT engine automatic start stop system?

stt is stop& Abbreviation for start. The STT Intelligent Fuel Saving System is a system that controls the start and stop of the engine. By implanting a reinforced motor with an idle start-stop function in the conventional engine, the engine is completely extinguished and does not work when the car meets the idle stop conditions.

When the whole vehicle needs to start and move forward, the idle start-stop motor system quickly responds to the driver's start command, quickly starts the engine, and connects instantaneously, thereby greatly reducing fuel consumption and exhaust emissions.

The system judges the state of the vehicle through the computer, such as the vehicle is in a stagnant state such as red light and blockage, and the computer can control the engine to automatically stop running, and the stop operation stage does not affect the use of air conditioning, audio and other equipment in the car. With this technology, fuel savings of up to 5% can be achieved under normal road conditions and up to about 15% in congested road sections. According to authoritative tests, the use of this technology will allow an average car to save 10% to 15% of fuel per year.

The start-stop function of the "stop-start" system is automatically activated by default when the key is energized, and the automatic stop system is activated when the vehicle speed is reduced below the limit, when the vehicle is in neutral and the clutch pedal is fully released. When the engine is successfully started, within a certain period of time, the driver does not have any pedals and gears to operate, the system will think that the driver has no intention of starting for the time being, and the engine will automatically stop. At this time, the compressor also stops working, and when the brake pedal is released to continue moving, the engine starts automatically.

Let me introduce you to the basic knowledge of the STT system The STT (Idle Start and Stop) function does not work under the following common conditions: 1) The vehicle starts cold, and the water temperature does not reach 40 degrees; 2) The speed of the vehicle does not exceed 10km h; 3) The battery is low; 4) Continuous automatic start is too frequent; 5) The left front door opens. In the above cases, the SS yellow light on the meter will always be on.

Chinese consumers are not familiar with this new technology, so let's first understand the new technology of automatic start-stop system. According to automotive experts, the automatic start-stop engine is to automatically turn off the engine when the vehicle is temporarily stopped while driving, such as waiting for a red light. When it's time to move on, the system automatically restarts the engine.

The engine starts and stops automatically.

As the name suggests, the engine intelligent start-stop system is (referred to as STT technology) when the vehicle is waiting for a red light or congested road conditions, normally press the brake to stop the vehicle and at the same time hang into neutral gear and release the clutch, the engine intelligent start-stop system starts, at this time the engine will stop working and enter the "fuel-saving mode".

To start the engine again, simply press the clutch, turn off the intelligent start-stop system of the engine, and then start in gear. To put it simply, in the manual transmission model, the engine intelligent start-stop system is to judge the engine start-stop control through the clutch, and the driver does not need to deliberately pay attention to the work of the system, and everything will not be affected by the normal state of driving.
