Engine start-stop technology (automobile start-stop technology: a new choice for energy saving and UEFA Champions League standingsenvironmental protection) With global warming and the strengthening of environmental protection awareness, automobile manufacturers have begun to adopt various new technologies and materials to promote energy-saving and environmental protection for automobiles.Engine start-stop technology is one of them, which allows us to save more fuel when driving and reduce harmful gases emitted by cars when idling. This article will introduce in detail the concept, working principle, advantages and future development trend of automobile start-stop technology. I. What is automobile engine start-stop technology? Car engine start-stop technology refers to the technology that the engine automatically turns off and restarts when the vehicle needs to continue to drive when the car is temporarily stopped while standing or driving. This technology can effectively reduce the harmful gases emitted by cars when idling, while saving fuel and reducing emissions. It is the latest energy-saving and environmental protection technology for automobiles. II. Working principle of automobile start-stop technology Automobile engine start-stop technology is mainly realized by the electronic control unit (ECU) installed on the vehicle. When you don't need motivationWait, for example, stop at a red light or drive slowly, the ECU will automatically turn off the engine and turn off the fuel delivery system. When the driver releases the brake or steps on the accelerator, the ECU will immediately start the engine to return the vehicle to driving. III. Advantages of automobile start-stop technology Automobile start-stop technology has the following advantages: 1. Save fuel. Cars use fuel in idling, because they need to maintain the operation of the engine and the use of auxiliary equipment. If the vehicle is always working in this state, whether it is driving or parking, it will lead to a waste of excess fuel. If engine start-stop technology is used, this situation can be avoided, so as to reduce fuel consumption and make the vehicle more energy-saving and environmentally friendly. 2. Reduce harmful gas emissions. Whether driving or parking, cars will emit harmful gases.However, in the idle state, because the engine does not work and only maintains the operation of the vehicle auxiliary equipment, the emission is relatively serious. The use of engine start-stop technology can reduce the emissions of the vehicle in idling, thus reducing environmental pollution. 3. Reduce noise pollution. Engine start-stop technology can reduce the noise made by the vehicle at idle speed. Moreover, if the driving environment is dangerous or needs to leave urgently, the vehicle can be started quickly again to ensure safety. IV. The future development trend of automobile start-stop technology. At present, more and more automobile manufacturers have begun to adopt start-stop technology in their new models. It is predicted that in the automobile market in 2020, models using engine start-stop technology will reach more than 50% of the total global sales. In the future, automobile start-stop technology will also be constantly improved and innovated, becoming more intelligent and environmentally friendly.For example, car start-stop technology will use rotor power generation and regenerative braking to charge the battery, thus improving the range of the car. In a word, automobile engine start-stop technology is the latest energy-saving and environmental protection technology for automobiles. It automatically turns off the engine and turns off the fuel delivery system through ECU, and can quickly start the engine when the vehicle needs to continue to drive. This technology can save fuel, reduce harmful gas emissions and noise pollution, and has a broader development prospect in the future.
