Regardless of your ambition, you need to face the harsh test of reality. For all car companies wishing to make a big achievement in the Chinese auto market, they will need to start a busy exam five years later from January 1, 2016. On this day, the country proposed to reduce the fuel consumption target to 5 liters per 100 kilometers by 2020, with the GB 19578-2014 "Passenger fuel consumption limit value" and GB 27999-2014 "Passenger fuel consumption evaluation method. And the official implementation of the indicators, announced the start of the final sprint. Lightweight, small-displacement, high-power turbocharged engine applications, pure electric and hybrid power car models are being promoted. Under the increasingly stringent fuel-related standards, various depots continue to promote new technologies and products to make He is even more "green" competitive. Among these new technologies, one technology is judged to be a standard high-speed device in the next five years. It is the start-stop system. The starting and stopping system works when the driver stops and picks up, for example when waiting for a red light or a traffic jam. The start-stop system shuts down the engine to reduce fuel consumption and carbon dioxide emissions. At this point, the battery is the only source of electrical energy for all electrical equipment on the car (air conditioning, radio and satellite navigation systems); when the driver releases the brake pedal, the engine will start again, an advanced start-stop system and a regenerative braking system, Energy management systems work together. Many vehicles are now equipped with this technology. Since the application of this technology to automobiles in 2007, more than 14 million vehicles in Europe have been equipped with this system by 2014, accounting for more than 60% of the total market. The number of new vehicles equipped with start-stop systems in the United States and China is also multiplying. However, it is conservatively estimated that by 2020, its equipment rate in the market will be above 40%. Why start and stop the system will be favored? Compared to the anxiety of electric vehicles, and the high cost of matching and promotion, the start-stop system does not change the driving and habits of consumers. It can help consumers achieve about 5% of fuel savings, and can also make manufacturers more efficient. Good to meet the country's fuel consumption and environmental assessment. The key is that the cost it adds to the vehicle is only around 3,000 yuan, and the cost of new technology to consumers is very small. At present, the only problem facing the start-stop system is the stability of the technology. Only a more powerful battery, starter, and generator can guarantee the efficient operation of the start-stop system. Specifically, the start-stop system requires a more powerful battery to provide sufficient electrical energy at idle to supply the vehicle's electrical equipment, support more frequent start-up, cycle and deep discharge, and partial charge to run and dynamic charge receiving capability, etc. . And these requirements can not be reached with ordinary batteries. According to the test results, ordinary batteries are assembled on vehicles with start-stop functions. After one week of use, the effective capacity of the batteries will be lost by 7% to 16%. At present, AGM batteries with outstanding cycle performance, charge acceptance, and outstanding ability to operate under low state of charge are the best choices for start-stop systems. The world-famous component brands Bosch and Walton of Johnson Controls are the main brands of AGM batteries in the domestic aftermarket. Among them, Valta's AGM start-stop battery uses the valve control of the adsorbed glass fiber bulkhead technology. Lead-acid sealed-battery batteries are the most advanced power reserve options for start-stop systems today, with excellent cycle performance, charge-receiving capability, and ability to operate in low-charge states. At the same time, domestic companies such as sail batteries are also increasing their R&D efforts on AGM batteries. In another five years, perhaps all the automotive products we purchase will have start-stop systems. Tips: Several small taboos for starting and stopping the system during daily driving: 1. Avoid starting and stopping systems in the case of ramps. The start-stop system can basically measure the slope of the road automatically to ensure that it is temporarily parked on the slope and the start-stop system will not be activated. However, for some gentle slopes, we also recommend avoiding the start-stop system as much as possible, because the start-stop system will have a short-term power delay, and it is easy to slip away when the brakes are released. 2. Close the start-stop system as far as possible in the state of traffic jam. Stop and stop traffic jams, if every stop has the start and stop system intervention, frequent engine start and stop will definitely bring you traumatic psychological, and easy to be jumped by someone else, it is estimated that it will not take long before you collapse. 3, when the fuel is insufficient, start and stop the system with caution. The start-stop system can indeed save fuel, but if the fuel indicator lamp has been alarmed, frequent use of the start-stop system will impose a greater burden on the fuel pump. 4, when wading, you must close the start-stop system. When passing through the wading road section, the start-stop system must be closed. If you forget that once the parking is stopped and the engine is shut down, the water can easily damage the engine from the back of the pipe. 1.What is UVC? 3535,2 pads,5 pads,Surface sterilization,quartz lens Bingri Electronic Technology (Shenzhen) Co., Ltd. , https://www.bingriuvled.com
UVC: The wavelength is between 100-280nm, but because the wavelength below 200nm is vacuum ultraviolet, it can be absorbed by the air, so the wavelength of UVC that can penetrate the atmosphere is between 200-280nm. The shorter the wavelength, the more dangerous it is. Can be blocked by the ozone layer, and only a small amount will reach the surface of the earth.
2.What is the mechanism of UV sterilization?
UV can destroy the DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) molecular structure of microorganisms, so that bacteria can die or cannot reproduce, so as to achieve the purpose of sterilization.
3.Where can UVC LED be used?
According to different application scenarios, we may be able to see UVC LEDs in these applications in the future:
Surface sterilization: high-frequency public contact surfaces such as medical appliances, maternal and child products, smart toilets, refrigerators, tableware cabinets, fresh-keeping boxes, smart trash cans, thermos cups, escalator handrails and automatic ticket machine buttons, etc.;
Still water sterilization: water tank, humidifier, ice maker;
Flowing water sterilization: Flowing water sterilization module, direct water dispenser;
Air sterilization: air purifier, air conditioner.
The wavelength range of UVC LED is generally around 260nm, 275nm and 280nm.
