For example, driving for less than 5 minutes at a time. Does it affect the car? Do you need a hot car? Long-term slow and short-distance driving, the most damaged is the battery, there is no good charging process, it is best to go out for a long walk every weekend. Whether it is long distance or short distance, it is best to idle for about 30 seconds. First, the battery life is shortened. Driving a short distance every day, the most direct impact is the battery. This is because electricity is needed to start the car, start the car and stop the car, and the car can only be recharged after it is started. Under short-distance use, the engine speed is not high, the charging current is very small, and the charging speed is quite slow. In this case, the daily power consumption of the car will be greater than the charging amount, the battery will be in an unsatisfied state, and even the original power will be gradually reduced, and then the electricity will not catch fire. After a long time, its life will inevitably be shortened. Second, short-distance driving with carbon deposition every day will also lead to obvious carbon deposition on throttle, air intake and fuel nozzle, which will indirectly lead to an increase in automobile fuel consumption. This is because during the ten minutes from home to the company, the car was in a cold state most of the time, the water temperature of the oil meter did not reach the best working state, the gasoline in the cylinder did not burn completely, and the carbon deposition increased obviously. On the other hand, if the speed can't be raised due to road conditions, traffic jams and other reasons, the carbon deposits generated by the engine will accumulate in these parts, and the most intuitive effects may be engine jitter, weak acceleration and jumping before braking. Third, increase fuel consumption In addition to the increase in carbon deposition, another hazard of short-distance use of cars is the increase in fuel consumption, because cars are in a cold state most of the time, especially in cold winter, resulting in a thick mixture and incomplete combustion, which is basically 2 to 3 liters more fuel consumption per 100 kilometers than vehicles that drive more every day. For office workers who drive to the company for more than ten minutes every day, they can drive to the high speed regularly to exercise their muscles, once a month 1~2 times. This will not only fully charge the loss-making battery, but also remove the carbon deposits generated inside the engine in time, and also make the internal components fully rotate and always maintain a good car state. Just as we need to exercise regularly, we don't know what kind of battery Porsche is. Generally, European cars are AGM, and your short-distance battery hurts the most. I suggest buying an AGM battery charger, which happened to my Audi. I didn't know that this self-starting battery is more expensive until I changed it. Hello, landlord, these short trips mainly affect the battery, which is easy to cause carbon deposition. If the cold car starts, it is best to wait until the engine speed is stable, and there is no need for the hot car to idle in place. @20 19
