Ministry of Transport**, during this year's Spring Festival, the number of non-commercial passenger cars on national highways and ordinary national and provincial trunk lines will be nearly 7.2 billion, and the proportion of self-driving travel will exceed 8%.
Because many people plan to drive home for the Chinese New Year, the topic of "how to drive on the highway more fuel-efficient" has attracted attention. Some people say that "the faster the car, the more fuel-efficient", is that true?
Di Yanbin, executive deputy secretary general of the China Automobile Maintenance and Maintenance Industry Association, told reporters that the statement that "the faster the car, the more fuel-efficient" is incorrect. He introduced that when the car is driving, when the speed reaches a certain value, there will be a minimum fuel consumption. This driving speed is known as economic speed.
When the car travels at a speed lower than the economic speed, the engine load is smaller, the combustion is not sufficient, and the fuel consumption is larger. When the car travels at a speed higher than the economic speed, the engine has greater air intake resistance and fuel consumption will increase significantly.
According to Di Yanbin, there are many factors that determine the economic speed of a car, including the type of vehicle, driving conditions, engine efficiency, etc. "However, generally speaking, the economic speed of a family car is generally between 60 and 90 kilometers per hour. He said.
Article 78 of the Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China stipulates that the speed of the highway shall be marked with the driving speed of the lane, and the maximum speed shall not exceed 120 kilometers per hour, and the minimum speed shall not be less than 60 kilometers per hour.
For self-driving travel during the Spring Festival, the public security department has given the following suggestions. First, when traveling by self-driving vehicles, you should understand the traffic information and traffic safety tips issued by the relevant departments in advance, and arrange the travel time and route reasonably. The second is highway driving, to maintain a safe distance, through congestion, slow road sections, do not intersperse at will, do not occupy the emergency lane. The third is to drive on rural roads, and when encountering sharp bends and steep slopes, long downhills, and roads near water and cliffs, it is necessary to slow down and drive slowly.
