In actual use, many car owners do not buy the automatic start and stop, and even choose to turn off this function as soon as possible after purchasing the car. So, is automatic start-stop a fuel-saving weapon, or just a flashy gimmick?
First of all, from the perspective of fuel economy, automatic start-stop can indeed save car owners some fuel expenses in some cases. According to the measured data, under urban driving conditions, especially in the congested road section of the morning rush hour, the fuel-saving effect of automatic start and stop is particularly obvious. In the test, the average fuel saving rate reached 751%, while in extreme congestion conditions, the fuel saving rate is even as high as 1492%, close to 15%. Assuming that 10,000 kilometers are driven every year and the fuel consumption is 10L per 100 kilometers, then the use of automatic start-stop can save about 75L of fuel. According to the current oil price, you can save 562 in a year5 yuan is indeed a lot of money.
However, the fuel-saving benefits of automatic start-stop are not without cost. Since this function needs to be activated frequently, a dedicated start-stop battery must be used. Compared with ordinary batteries, the ** of start-stop batteries is higher. For example, a 60-ampere-hour VARTA AGM battery costs about 900 yuan, while a regular battery costs only about 300 yuan. In addition, the life of the start-stop battery is generally required to be more than two years, which means that in the worst-case scenario, the battery will be replaced once every two years, and then the additional 600 yuan spent on replacing the battery will be deducted, and the actual fuel-saving income is only more than 500 yuan.
In addition to economic considerations, the automatic start-stop experience also makes some car owners feel uncomfortable. Many car owners report that when stopping at a short red light, the sudden start of the engine will not only cause discomfort to the passengers in the car, but also increase the vibration and noise of the vehicle. In addition, some owners also said that after turning on the automatic start-stop function, the vehicle's acceleration response and air conditioning performance were affected.
Despite these drawbacks, it is undeniable that automatic start-stop does play a positive role in environmental protection. This feature helps to reduce the vehicle's tailpipe emissions when idling, thereby reducing environmental pollution. According to the first experiment, after the start-stop system is adopted, the carbon monoxide, nitrogen oxide and hydrocarbon emissions in the automobile exhaust are reduced. 3%。Okay, I'll share it here today, like and follow, and we'll see you next time!
