Often running at high speed, is the car in better condition or more worn?

Frequent high-speed driving will affect the running logic of ECU and change the driving experience. "Lighter throttle" is the truth. The ECU is adaptive and will change the operation logic. Nowadays, cars are very intelligent and have adaptive learning function.

Beijing Institute of Technology has a paper "Engine Control System Based on Vehicle Power Transmission Integrated Control", which says that the ECU of a vehicle has certain adaptive ability and will change the logic of air intake, combustion and gear shifting according to the driving habits of users.

Let's talk about combustion logic first. The ECU of the vehicle driving computer senses different road conditions and vehicle conditions through sensors, and the fuel fine-tuning function of the ECU will intervene to correct the fuel injection pulse width. When running at high speed, ECU will supply oil more actively. Suddenly returning to the city at a high speed, the ECU did not respond, and the more economical energy-saving mode was not adjusted. The oil is still given very actively, and the throttle naturally feels faster.

When the car is driving at high speed, the engine is in the range of "high speed, medium and high load". At this time, the intake speed is fast, the engine working condition is relatively stable, the combustion insufficiency rate is reduced, and the carbon deposition speed is reduced. Cars that often drive at high speed usually have cleaner engines than cars that often drive in cities.

Cars running at high speeds tend to have longer battery life. Usually, it takes about 20 to 30 minutes for a car battery to be fully charged. As we have said in the previous article, even if the vehicle is turned off, it will consume electricity.

On average, in two weeks, the battery will enter a low-power state, and it will be exhausted in about 1 to 2 months. Northeastern University has an article entitled "Optimization of Pulse Fast Charging Process and Research on Sulfurization Failure of Lead-acid Battery", in which it is said that if the battery is too low or even exhausted, the automobile battery will undergo vulcanization reaction, the performance of electrolyte and electrode will be greatly reduced, and the battery will be scrapped in advance.
