There are not a few models equipped with automatic engine start-stop technology. Is it the first thing that many friends get on the bus, that is, turn off this feature. Some people are even discussing how to get the car off for a long time, so that you don't have to manually turn it off each time you start the car. How deep do you know about automatic start and stop?
“Automatic start-stop†is not a particularly advanced technology that has been around since the 1930s and was not widely used in traditional models until the mid-1980s. In 1984, the automatic start-stop technology was first applied to Volkswagen Golf (participation, picture, inquiry) diesel engine. Subsequently, many car brands began to test the system in small batches, such as Mazda, Honda, Citroen, GM and so on. In 2007, the technology began to be used in high-volume applications on BMW models.
Nowadays, this configuration has appeared on many models, not only exclusive cars such as BMW and Mercedes-Benz, but also some models such as Mazda, Roewe (Weibo) and Emgrand. All models are equipped with automatic start and stop devices as standard. According to the survey, in 2014, about 7% of the new models in the Chinese market were equipped with this technology, about 2 million, which is six times that of 2013. The growth momentum is very strong, and according to foreign media reports, Ford Motor plans to achieve 70% of its models in 2017 with automatic start and stop.
The engine automatically starts and stops with the English name STOP & START referred to as STT, which is a system that can automatically control engine flameout and ignition. Vehicles equipped with automatic start-stop will temporarily stop during driving. For example, when the red light is waiting, it will automatically turn off. When it needs to continue, the system will automatically start the engine. Its core technology is to automatically control the flameout and start-up, in order to save fuel, because after the engine is turned off, the battery will replace the pulley to provide power for the engine cooling fan and the interior air conditioner, thus reducing unnecessary fuel consumption. Reducing emissions also increases fuel economy.
The engine start and stop is to automatically stop the fire when the vehicle is temporarily stopped during driving (for example, waiting for a red light). When it is necessary to move on, the system automatically restarts the engine's system. The method used is as long as the brake pedal is directly pressed while driving, the engine will automatically turn off after the vehicle is completely stopped for about two seconds, and the engine will remain closed when the brake pedal is pressed all the way. As soon as the brakes are released, or the steering wheel is turned, the engine will automatically ignite immediately, and the accelerator can be started immediately. The whole process is in the D-stop state.
What is the use:In traffic jams and other red lights, the engine can automatically turn off and re-ignite at the start, reducing unnecessary fuel consumption and reducing emissions.
Analysis of advantages and disadvantages of engine start-stop technology(1) Engine start-up technology advantages: automatic control of flameout and start-up, while reducing unnecessary fuel consumption, reducing emissions and improving fuel economy. When waiting for traffic lights or traffic jams in urban traffic, it can minimize the engine idle idle time, and after the engine is turned off, its power supply can replace the pulley to provide operating power for the engine cooling fan and the interior air conditioner.
(2) Engine start-up technology disadvantages: a more durable starter and high-quality engine oil are required. The general starter design allows for a large operating current, but the use time is very short. Repeated use of the starter is likely to cause overheating damage to the starter, so a starter with automatic start and stop function must be much more durable than a normal starter. Moreover, high-quality oil must be used to prevent the air conditioner from being turned on. The battery is very low, the temperature outside the vehicle is too high or too low, and the system does not start when the pressure in the brake system drops below a certain point.
Advanced and reasonable system design, stable display effect, easy installation and maintenance, high definition and high resolution. All-day work: vivid colors, high refresh rate, anti-static, dust-proof, good heat dissipation effect, and high cost performance. Display mode: move left and right , moving up and down, pulling the screen left, pulling the screen right, opening and closing in the middle, flickering, display and other methods. Using the program editing and playing software, you can edit, add, delete and modify text, graphics, images and other information through the mouse. The content of the arrangement is stored in the control card, and the information playback is automatically displayed in a loop according to the program table.
